    Description: Auf der Basis von Mikrofaunen-Untersuchungen wurden die Corbicula- Schichten des Mainzer Beckens s. str. feinstratigraphisch-paläoökologisch bearbeitet. Die Untersuchungen stützten sich auf detaillierte Geländeprofile vom Sommerberg, südwestlich Alzey und aus den Steinbrüchen bei Göllheim, Oppenheim/Nierstein und Rüssingen. Für den stratigraphischen Bereich vom höchsten Teil der Oberen Cerithien-Schichten bis in basale Lagen der Hydrobien-Schichten werden 4 Profilabschnitte nachgewiesen, in denen ein verstärktes Auftreten von Foraminiferen und brackischen Ostrakoden auf eine Erhöhung der Salinität im ehemaligen Ablagerungs- und Lebensraum schließen läßt. Ökologische Faktoren können jedoch unterschiedliche Mikrofaunen- Assoziationen an den verschiedenen Untersuchungspunkten eines gleichen stratigraphischen Niveaus bedingen. Das Einsetzen des Ostrakoden Hemicyprideis lienenklausi Marz in mittleren Lagen der Corbicula-Schichten ermöglicht eine Zweiteilung in Untere und Obere Corbicula-Schichten. Als mikrofaunistisches Abgrenzungskriterium Obere Cerithien-Schichten/Corbicula- Schichten wird das Erlöschen von Hemicyprideis rhenana (LienenkLaus) herangezogen. Gleichzeitig ist an der Wende Obere Cerithien-Schichten/Corbicula-Schichten ein scharfer ökologischer Wechsel von brackischen zu limnischen Verhältnissen zu beobachten. Die Grenze Corbicula-Schichten/Hydrobien-Schichten ist mikropaläontologisch nicht exakt faßbar. Sicherstes Abgrenzungskriterium bleibt daher das Erlöschen von Hydrobia inflata (Liu). Die Foraminifere Nonionoides demens (BıXx) und der Ostrakode Cypridopsis (Obliquopsis) obliqua Maız setzen in höheren Lagen der Corbicula-Schichten sehr vereinzelt ein. Individuenreiche Populationen dieser Arten können als sicherer Hinweis auf Hydrobien- Schichten angesehen werden. Im Kapitel Mikropaläontologie werden die stratigraphisch wichtigen Hemicyprideis- Arten (Östracoda) beschrieben und abgebildet. Die Foraminiferen-Gattungen Neobulimina CusHMANn & Wickenpen und Glabratella Dorreen werden erstmalig für das Mainzer Becken nachgewiesen.
    Description: Abstract: Based on investigations of microfaunas the Corbicula beds of the Mainz basin s. str. are researched biostratigraphically and paleoecologically. The investigations rely on sections from a road cut near Alzey and at the quarries of Göllheim, Oppenheim/ Nierstein and Rüssingen. Four stratigraphical sections can be proved which are characterized by increased appearance of foraminifers and brackish ostracods from the uppermost part of the Upper Cerithium beds up to the basal layers of the Hydrobia beds. These sections indicate increases of salinity in the paleoenvironment. Other ecological factors can imply different microfauna associations at several points of investigation within the same stratigraphical horizon. A subdivision into Lower Corbicula beds and Upper Corbicula beds is possible by the first appearance of the ostracod Hemicyprideis lienenklausi Maız in the middle layers of the Corbicula beds. The micropaleontological delimitation Upper Cerithium beds/Corbicula beds is defined by the extinction of Hemicyprideis rhenana (Lienenktaus). The boundary Upper Cerithium beds/Corbicula beds is also characterized by a sharp ecological change from brackish to fresh-water conditions in the paleoenvironment. An exact micropaleontological criterion to define the boundary Corbicula beds/Hydrobia beds was not found. The extinction of Hydrobia inflata (Lıuı) is considered as the best biostratigraphical datum to limit the Corbicula beds from the Hydrobia beds. The ostracod Cypridopsis (Obliquopsis) obligqua Maız and the foraminifer Nonionoides demens (Bıx) appear at the first time in the upper parts of the Corbicula beds and populations rich in these species can be taken as a sure hint to Hydrobia beds. The stratigraphical important species of the genus Hemicyprideis (Ostracoda) are figured and described. For the first time the foraminifer genera Neobulimina CusumAan & WICKENDEN and Glabratella Dorrzen are evidenced at the Mainz basin.

    Description: In bisher als fluviatil angesehenen tertiären Sedimenten im Durchbruchstal des Guldenbaches durch den Taunusquarzit-Härtlingszug des Soonwaldes kann aufgrund sedimentpetrographischer und mikrofaunistischer Analysen eine Verzahnung von fluviatilen mit marin-brackischen Ablagerungen des oberen Rupels (= Schleichsand) belegt werden. Das Schleichsandmeer des Mainzer Beckens und seines Ausläufers, der „Stromberger Bucht”, benutzte das prämitteloligozäne Guldenbachtal als schmalen Korridor in den Ost-Hunsrück. Weitere Vorkommen von mehr oder weniger tonigen Quarzkiesen im Ost-Hunsrück werden beschrieben. Eine Diskussion ihrer Bildungsbedingungen sowie Foraminiferenfunde führen zur Annahme litoraler Ablagerung zur Zeit des Schleichsandmeeres oder im tieferen Chatt. Die angenommene Küstenlinie erlaubt als tektonischer Bezugshorizont die Feststellung einer nach SW unbedeutender werdenden Flexur am Hunsrücksüdrand sowie einer Kippung des Ost-Hunsrück - mit Ausnahme der Moselmulde - nach Süden um ca. 50 m. Weiterhin spricht einiges für eine zusätzliche Kippung vor allem der südlichen Teile nach Osten.
    Description: Abstract: Tertiary sediments in the narrow gap of the stream Guldenbach in the monadnocks of the Taunusquarzit of the Soonwald mountain ranges were up to now thought to be of a fluvial origin. Investigations of the sedimentary petrography and microfauna prove that fluvial sediments dovetail with marine or brackish ones of upper Rupelian age (Schleichsand). The sea, which transgraded from the Mainz basin into the Stromberg embayment at that time, used the preexisting valley of the stream Guldenbach as a narrow corridor into the Eastern Hunsrück. Furthermore some relics of more or less clayey quartz gravels, some of which contain Foraminiferae, are described. The discussion of their sedimentary environment leads to the hypothesis of a litoral sedimentation of the upper Rupelian or Chattian sea. The supposed shoreline as a tectonic reference level shows a flexure at the southern boundary of the Hunsrück with decreasing amounts of uplift towards Southwest. The Hunsrück itself - except the Moselle syncline in the northernmost parts - was tilted southwards with a maximum uplift of about 50 m, and perhaps eastwards, too, especially in the southern parts.

    Description: Nach Vorarbeiten 1977 und 1979 wurden im Bereich der paläolithischen Fundstelle Şehremuz im Jahre 1982 zwei Grabungskampagnen von je zwei Monaten durchgeführt. Es konnten zwei archäologische Komplexe in unterschiedlicher geologischer Lagerung festgestellt werden: a) Silexabschläge und Faustkeile im obersten aufgeschlossenen Schotter des Keluşk-Baches, eines Euphratzuflusses. Dieser Seitentalschotter ist korrelierbar mit einem etwa 60 m über der heutigen Talaue liegenden Euphratschotter. b) „Mittelpaläolithische" Inventare in einem über den Keluşk-Schottern liegenen Glacis, weitgehend nur aus Oberflächenfunden bekannt. Sie sind aufgrund ihrer Einlagerung jünger als der "Faustkeilkomplex". Die Inventare mit Faustkeilen sind einem entwickelten faustkeilführenden Paläolithikum zuzurechnen. Auf sie ist die vorliegende Untersuchung konzentriert. Die durch die Silexartefakte belegten zahlreichen Begehungen des alten Keluşk-Bettes durch den paläolithischen Menschen haben ihre Ursache u.a. in einem hohen natürlichen Anteil von Silex im Schotter. Neben vollständigen Knollen liegt zahlreicher Naturbruch vor, der gegen die Stücke mit anthropogenen Bearbeitungsspuren abgegrenzt werden muß. Dabei kommt der Konfiguration der Einzelmerkmale — Dimensionen; Abbaufläche und Schlagmerkmale — die größte Bedeutung zu. Die Bearbeitung der Steinartefakte unter funktionalen Gesichtspunkten ist ein wichtiger Teil der Untersuchungen: Die Methoden werden beschrieben. Form und Zurichtung der Faustkeile lassen makroskopisch mögliche Funktionsflächen zum tiefen Einschneiden etwa in Fleisch und mögliche Funktionskanten zum Ritzen oder flach Einschneiden erkennen. Im mikroskopischen Bereich werden an Artefakten punktuell Gebrauchsspuren faßbar, die z.B. die Benutzung eines Faustkeils sowohl zum Einschneiden in Fleisch wie auch zum Zertrümmern von Knochen belegen.

    Description: Im unteren und mittleren Werratal läßt sich eine 5—8 m ü. Talaue gelegene Terrasse ausgliedern, die an mehreren Lokalitäten eine weite Verbreitung hat und aufgrund ihres Aufbaus und ihrer Deckschichten (z.T. Löß) als hochwürmzeitliche Niederterrasse eingestuft wird. Sie wurde schon im Spätglazial durch 0,5—1,0 m tiefen Rinnen zerschnitten, die von wahrscheinlich umgelagerten Niederterrassenschottern oder feinkörnigeren Sedimenten wieder aufgefüllt wurden. Die spätglaziale und frühholozäne Flußgeschichte läßt sich dank zeitweilig günstiger Aufschlußverhältnisse bei Eschwege recht gut rekonstruieren (Abb. 6 und 7). Dies gelingt hier besser als im Werraabschnitt auf dem Gebiet der DDR, der von Ellenberg (1967 bis 1975) sehr genau untersucht worden ist. „Ried"ablagerungen in ehemaligen Werrarinnen können präallerödzeitlichen und jungtundrenzeitlichen bis borealen Alters sein. Wie im Leinetal finden sich im Werratal zwei verschieden alte Auelehme, von denen der ältere stellenweise eine wahrscheinlich dem postglazialen Klimaoptimum zuzuordnende Auen-Schwarzerde trägt. In den „Ried"ablagerungen konnten 12 Flußmuschel- bzw. -Schneckenarten gefunden und bestimmt werden.

    Description: Der Bereich des Meßtischblattes 6311 Lauterecken im Saar-Nahe-Gebiet (SW-Deutschland) wurde anhand einer geologischen, ingenieurgeologischen, hydrogeologischen und morphologischen Untersuchung einer Stabilitätsanalyse der Hänge und Böschungen unterzogen, die durch die Verwertung klimatologischer Daten vervollständigt wurde. Das Ergebnis liegt in einer Stabilitätskarte sowie in einer Analyse der gesammelten Daten vor. Soweit die Untersuchung des Modellgebietes von ca. 130 km21 Größe (etwa 5% der Fläche des Saar-Nahe-Gebietes) eine Antwort zuläßt, sind Hänge und Böschungen im sedimentären Rotliegenden des Saar-Nahe-Gebietes bereits ab 7° Hangneigung potentiell rutschgefährdet. Das rutschgefährdete Areal umfaßt etwa 10% der untersuchten Fläche. Ca. 2,6% wurden von Massenbewegungen betroffen. Kriechen und Gleiten sind die häufigsten Arten der Massenbewegungen. Die beteiligten stratigraphischen Einheiten sind neben den Deckschichten die Quirnbacher, Jeckenbacher und Lautereckener Schichten des Unteren Rotliegenden. Künstliche Böschungs-, An- und Einschnitte in den für das Unterrotliegende charakteristischen Wechsellagerungen von Ton-, Schluff- und Sandsteinen, stellen ein permanentes Stabilitätsproblem dar.
    Description: Abstract: This report deals with the analysis of stability of slopes which occur on the map of Lauterecken, Saar-Nahe-area, SW-Germany. A geological, engineering geological, hydrogeological and morphological study was made, additionally, climatological data were taken into account; the results of it are analyzed and plotted in a stability map. Conclusions: Taking the regarded territory of approximately 130 km2 (about 5% of the area of the Saar-Nahe-area), it can be stated that slopes in the Saar-Nahe-area are potential landslide areas, if the inclination of the slopes is 7° or more. Within an area of 10% landslides are probable to take place. Within 2,6% mass movements happened or are going on. Creep and sliding are the most abundant forms of mass movements. Slope instability occours preferentially in weathered rocks, Quirnbach beds, Jeckenbach beds and Lauterecken beds of the Lower Permian. Steep roadcuts occurring in alternating sandstone and siltstone beds are very likely to cause stability problems.

    Description: Durch moortypisches Wetter eingestimmt, trafen sich die Mitglieder und Freunde der IMTG zu ihrem 7. Kongreß, der zugleich die 30-jährige Wiederkehr eines ersten Treffens von Experten der Moore und Torfe 1954 in Dublin feierte. Die internationale Moor- und Torffamilie ist inzwischen nach Zahl und Inhalt sowie ihren Statuten gewachsen. Etwa 400 Teilnehmer aus 25 Ländern wurden gezählt, leider weniger als ursprünglich erwartet. Sie verteilen sich wie folgt: EG-Länder 193 Teilnehmer, Skandinavien 103, Nordamerika 56, Osteuropa l9, Asien l7, Südamerika 8 und Afrika 3 Teilnehmer. Die Teilnehmerzahl spiegelt also auch in etwa die Bedeutung der Moorvorkommen in den Regionen wider. Die stärksten Delegationen kamen neben dem gastgebenden Irland (99) aus Finnland (69), Bundesrepublik Deutschland (40), Kanada (33), Großbritannien (27), U.S.A. (22). Besonders herzlich begrüßt wurden relativ große Gruppen aus der Volksrepublik China, Japan und Brasilien. [...]

    Description: Die Toskana ist die stärkste geothermische Anomalie auf dem europäischen Kontinent. In dieser Anomalie finden sich zahlreiche lokale geothermische Felder mit hoher Enthalpie, wie z.B. das Feld von Travale. In diesem geothermischen Feld, das im Era-Graben liegt, wurden in den Jahren 1980/81 elektromagnetische Messungen durchgeführt. Es war das Ziel der Untersuchungen, die Quelle und die Ursache dieser teilweise bekannten Anomalie zu finden. Hierzu sollte die Verteilung der elektrischen Leitfähigkeit in der Erdkruste bis in Tiefen der Kruste-Mantel-Grenze mit den Methoden der Magnetotellurik und Erdmagnetischen Tiefensondierung untersucht werden. Parallel dazu wurde die geothermische Anomalie von Travale mit einer Vielzahl weiterer elektromagnetischer, seismischer und geochemischer Methoden untersucht. Das Ziel, die geothermische Anomalie in der Erdkruste zu lokalisieren, war nicht einfach zu erreichen. Deshalb war es notwendig, ein Modell der Anomalie zu erarbeiten, aus dem die Lokalität folgen sollte. Vor angegangene elektromagnetische Untersuchungen (HAAK & SCHWARZ 1981) hatten gezeigt, daß nahezu das gesamte Gebiet der Toskana als eine Anomalie der elektrischen Leitfähigkeit anzusehen ist: Gutleitende Deckschichten, mit bis zu 10 km Mächtigkeit, werden von einem hochohmigen Basement unterlagert. An einigen Meßorten deutet sich der Übergangsbereich Kruste / Mantel - in einer Tiefe zwischen 20 und 30 km - durch eine Zone hoher Leitfähigkeit an. Dieser Bereich zeichnet sich durch Lamellen hoher und extrem niedriger seismischer Wellengeschwindigkeiten aus. Petrologisch kann dieses durch eine Wechsellagerung von basischem und saurem Material gedeutet werden. Die zeitlichen Variationen des elektrischen und magnetischen Feldes wurden im geothermischen Feld von Travale in einem breiten Periodenbereich von 6 - 10.000 s registriert. Die Meßorte liegen überwiegend auf zwei Profilen, eines verläuft parallel zum Era-Graben aus der Anomalie heraus nach NW, das zweite schneidet die Anomalie senkrecht zum Graben. Der Meßpunktabstand war mit einigen hundert Metern bis zu mehreren Kilometern sehr dicht, um möglichst alle lateralen Variationen der scheinbaren spezifischen Widerstände beobachten zu können. Es zeigte sich, daß die lateralen Variationen der spezifischen Widerstände im Gebiet von Travale sehr groß waren. Bis zu Perioden von 50-100 s ist der Era-Graben die dominierende zweidimensionale Leitfähigkeitsstruktur. Die gemessenen scheinbaren spezifischen Widerstände sind bei längeren Perioden durch dreidimensionale Leitfähigkeitsstrukturen verzerrt. Die scheinbaren elektrischen Widerstände sind innerhalb der geothermischen Anomalie mit Werten bis zu 50 Qm äußerst klein, während sie nördlich des geothermischen Feldes auf 100-300 Qm ansteigen, um dann etwa 7 km NW der Anomalie wieder deutlich abzufallen. Selbst in der tieferen Kruste werden keine höheren Widerstände angetroffen. Die integrierte Leitfähigkeit weist das geothermische Feld ebenso als eine Anomalie der elektrischen Leitfähigkeit aus, während nördlich davon die "hochohmige Barriere" bestätigt wurde. Aus den Ergebnissen der Seismik und Magnetotellurik wurde ein Modell für die geothermische Anomalie von Travale und die Toskana abgeleitet, das sich in drei Stockwerke gliedert: - Das unterste Stockwerk, die Übergangszone zwischen Oberem Mantel und Unterkruste in 20-30 km Tiefe ist die Quelle auf steigender heißer Gase und Flüssigkeiten. Die Temperatur beträgt etwa 700° C. - Das mittlere Stockwerk ist von tief reichenden, vertikalen Störungen durchsetzt, die einen konvektiven Wärmetransport durch die hydrothermalen Phasen in das oberste Stockwerk erlauben. Im Gebiet von Travale hat sich durch längs- und zum Era-Graben querstreichende Störungen eine ausgeprägte Schwächezone in der Kruste gebildet, die einen besonders intensiven Wärmetransport zuläßt. Der Temperaturgradient wird mit 15° C/km angenommen. - Das oberste Stockwerk besteht aus Sedimenten und kristallinen Formationen, die im wesentlichen von horizontalen Abscherungs- und Störungsflächen durchzogen sind, in denen hydrothermale Phasen zirkulieren. Innerhalb der Basements hat sich so ein zweites Reservoir ausgebildet, welches das bekannte geothermische Reservoir in den Karbonaten in Tiefen von 1-2 km durch ein ausgeprägtes Bruchsystem speist. Die Temperatur ist in 4 km Tiefe mit 400° C sehr hoch. Die augenblicklich geförderten heißen Gase und Wässer sind meteorologischen Ursprungs und werden an der Oberkante des toskanischen Basements aufgeheizt. Aus tektonischer Sicht besteht das oberste Stockwerk aus allochthonen Decken, die während der Orogenese über die Toskana hinweggeschoben wurden. Dieser tektonischen Kompressionsphase folgte eine Phase starker lateraler Dehnungen, die bis heute andauern. Das System von Grabenbrüchen und tiefgreifenden Verwerfungen ist Ausdruck dieser Dehnungstektonik. Die damit verbundenen Störungszonen tragen zu einer Entwässerung und Entgasung der tiefen Erdkruste bei und lassen die hydrothermalen Phasen in das oberste Stockwerk aufs teigen. In ausgeprägte Schwächezonen, die die gesamte Kruste durchziehen und die durch undurchlässige Schichten nach oben abgeschlossen werden, kann sich so ein geothermisches Reservoir ausbilden.
    Description: Tuscany is the strongest geothermal anomaly in continental Europe. Numerous local high enthalpy geothermal fields are to be found within this anomaly, e.g. the Travale field. Electromagnetic soundings have been carried out in this geothermal field, which lies in the Era-Graben, in the years 1980 and 1981. The aim of this study was to find the origin as well as the cause of this partly known anomaly, using the methods of magnetotelluric- and geomagnetic depth soundings to study the distribution of electrical conductivity in the earth's crust downwards to the crust/mantle boundary, at least. Parallel to this study the geothermel anomaly of Travale has been studied with the help of various other methods, including electromagnetic, seismic and geochemical surveys. To localize the geothermal anomaly in the earth's crust was not an easy task. Therefore it seemed to be necessary to develop a model of the anomaly, first, and then to localize it. Earlier electromagnetic investigations (HAAK & SCHWARZ 1981) have shown, that nearly the whole area of Tuscany corresponds to an electrical conductivity anomaly: A well conducting cover, reaching down to 10 km depth is underlain by a high resistive basement. At some places within the geothermal anomaly a zone of high conductivity has been found at the depth of the crust/mantle-boundary (between 20 and 30 km) . Seismic refraction measurements are indicating a wide transition zone between the crust und upper mantle, displayed by alternating high- und extreme low-velocity layers. The time-varying electric- and magnetic fields have been recorded in the Travale area in a broad period range from 6-10.000 s, mainly on two profiles, the one parallel, the other perpendicular to the Era-Graben. The stations have been very close to each other, spacings varied between some hundreds of meters and a few kilometers, to study lateral variations of apparent resistivities within the Graben. In deed, lateral variations of apparent resistivities have been very large in the Travale area. Up to 50-100 s the Era-Graben is the dominating 2D-structure, but for longer periods of investigation the three-dimensionality of the electrical conductivity structure has to be considered. The apparent resistivities inside the geothermal anomaly are extremely low, reaching not more than 50 Gm, even in the lower crust, whereas going up to 100-300 firn north of the geothermal field. Further to NW apparent resistivities are coming down again to 5-5o Gm. Total conductance as well indicates the geothermal field as a local conductivity anomaly, whereas more to the north the poorly conducting "barrier" has been confirmed. Based on the results of the magnetotelluic soundings and those of the seismic survey a geothermal model for the anomaly of Travale as well as for Tuscany has been developed. The crust is built up by 3 stories: - The lowermost story of the transition from the mantle to the crust at 20-30 km depth has to be regarded as the origin of hot gases and fluids. Temperature amounts to 700° C. - The central story is more or less fractured vertically so that pathways allow convective transport of heat by means of hydrothermal fluids to the upper story. In the Travale area a weak crustal zone of faults crossing over has developed, allowing the transport of heat to be very intensive. The temperature gradient is assumed to reach not more than 15° C/km. - The uppermost story consists of sediments and more or less horizontally fractured crystalline formations, filled with hot, circulating fluids. Within the basement a second reservoir has evolved, which feeds the known geothermal reservoir in the carbonate series at 1-2 km depth through fractures and cracks in the top of the basement. The temperature of about 400° C in 4 km depth is extremely high. The actually exploited hot gases and fluids are of meterological origin and heated up at the top of the basement. From the tectonic point of view, the uppermost story consists of allochthonous nappes shifted across Tuscany during orogenesis. This compressive tectonic deformation was followed by strong dilatational forces, which are still active in the whole crust, expressed by the features of graben structures and deep reaching faults. This process gives volatiles and water generated by dehydration in the deep crust the chance to rise to the uppermost story. A basement fractured at the top and an impermeable cover in the uppermost layer will then favour the development of a geothermal reservoir.

    Description: Die Mächtigkeitsreduktion des Mittleren Buntsandsteins von ca. 600 auf ca. 125 m zwischen dem Zentrum der nördlichen Hessischen Senke in Richtung Eichsfeld-Altmark-Schwelle ist bereits nachgewiesen. Die extremen Mächtigkeitsunterschiede innerhalb einzelner Folgen werfen jedoch Fragen nach dem Sedimentationsmechanismus und einem lateral verfolgbaren Sedimentations-Modell auf. In wieweit lassen sich Einzelsequenzen innerhalb einer Folge im Bereich der Schwellen- und Trog-Position faziell vergleichen und welche Konsequenzen hat dies für die Lithostratigraphische Abgrenzung? Aktuelle Isopachenkarten für die einzelnen Folgen des Mittleren Buntsandsteins (Hessen/Thüringen) zeigen ein differenziertes Bild im Bereich der Eichsfeld - Altmark - Schwelle. Die Analyse der paläogeographischen Daten und Schüttungsrichtungen lassen erkennen, daß z.Z. der Volpriehausen-Folge die nördliche Hessische Senke noch mit der Thüringer Senke in Verbindung stand. Die Schwellenregion wirkte sich erst während der Detfurth- und Hardegsen-Folge immer stärker auf die Sedimentation aus. Die Faziessequenz im Bereich der maximalen Absenkung (Raum Kassel -Karlshafen) umfaßt folgende Einheiten: regressive Flachwasser-Sequenz (Strand-/Vorstrand) (smV, A Top), alluvial/äolische Sedimentfolge (D, s), lakustrine Sedimente (D, st), Playa-Sedimente (D, t) und fluviatile Sedimente (H 1). Die vergleichbare Schichtenfolge am Westrand der Eichsfeld - Altmark - Schwelle (Raum Eschwege - Treffurt) besteht aus fluviatilen Sedimenten (V, s), einer fluviatil -tidal -lakustrinen Sedimentfolge (V, st) und fluviatilen Sedimenten (D, s), die von Oberfl utungs-Sedimenten überlagert werden (D, st).

    Description: Großrestuntersungen aus den Torfschichten eines Hochmoores bei Sellstedt (Krs.Cuxhaven) zeigten vielfältigen Vegetationswechsel. Die Moorbildung begann mit einem Birkenbruchwald. Später folgten verschiedene Hochmoorgesellschaften (Scheuchzerio-Caricetum limosae, Sphagnetum magellanici, Sphagnetum papillosi, Sphagnetum imbricati u.a.). Ein alternierender Bult- Schlenkenwechsel, wie früher vielfach angenommen, konnte nicht nachgewiesen werden. Neue Gesichtspunkte zu den Ursachen der Vegetationsumschichtungen werden diskutiert.
    Description: In a bog near Sellstedt (Kr. Cuxhaven) macrofossil investigations have been made. By the results various plant successions have been pointed out. The development of the mire started with a birch swamp. Later, different bog plant-associations followed (Scheuchzerio-Caricetum limosae, Sphagnetum magellanici, Sphagnetum papillosi, Sphagnetum imbricati). An alternating hummock-hollow formation process, as assumed in former days, could not be observed. New aspects of the causes for the shift of the vegetation are discussed.

    Description: Im zentralen Anti-Atlas wurden die Deformationen im sedimentären Deckgebirge des präkambrischen Kristallin-Aufbruchs des J. Sirwa und angrenzender Grundgebirgs-Blöcke untersucht. Dabei konnten zwei unterschiedliche Deformationsformen erfaßt werden. Als erste Generation entstanden - bisher a l s tektonisch angesehen - in zwei Niveaus frühdiagenetische Deformationsstrukturen (Gleitfalten, Rutschungen und Setzungsstrukturen), die zum Teil sehr große Dimensionen erreichen. A l s Auslöser für diese Verformungen müssen Kompaktionserscheinungen und eine leichte Reliefbildung angenommen werden. Hinzu kam in einzelnen Fällen auch ein übernormaler Porenwasserdruck. Eine vermutlich spätpaläozoische tektonische Deformation hat diese frühen Deformationsstrukturen überprägt. Satelliten- und Luftbild-Interpretationen sowie Geländebeobachtungen zeigen, daß die während der variskischen Orogenese aufgestiegenen Kristall in-Dome an bereits im späten Präkambrium angelegte Bruchsysteme gebunden sind. Darüber hinaus geben die Deformationen im Deckgebirge keine Hinweise auf die Mechanismen der Dom-Aufstiege. Während dieser Aufstiege kam es zu einer weitspannigen Verfaltung der Sedimente des Deckgebirges. Vergleiche zwischen den ursprünglichen Faltenachsen-Richtungen der frühen Deformationsstrukturen und den tektonischen Faltenachsen sowie den Störungssystemen im Grund- und im Deckgebirge zeigen, daß auch das altpaläozoische Deckgebirge von den prakambrisch angelegten Störungssystemen beherrscht wird, wobei in einer frühen Phase der Sedimentation die frühdiagenetischen Deformationsstrukturen an den Störungslinien gebildet wurden. Die gleichen Störungssysteme haben dann im Spätpaläozoikum auch bei der Tektogenese das beherrschende Element dargestellt. Wie an postpaläozoischen Störungen und Kluftbildungen in mio-pliozänen Vulkaniten nachgewiesen werden konnte, sind die alten Störungs-Richtungen bis in jüngste Zeit reaktiviert worden und prägten sich auch bei der im Känozoikum erfolgten Hebung des Anti-Atlas aus.

    Description: Mit Hilfe der Mikrofazies-Analyse wurde die paläogeographische Entwicklung des Sedimentationsraums der obertriassischen Gesteinsabfolge im Bereich der Vorarlberger Kalkalpen rekonstruiert. Die Entwicklung begann mit der Ausbildung eines weiträumigen, sehr flachen Schelfgebietes im Nor (Hauptdolomit). Durch stärkere, aber nicht einheitliche Absenkung im Oberen Hauptdolomit und im Plattenkalk-Niveau bildete sich ein Relief aus. Die hier einsetzende Schüttung terrigenen Materials erreichte während der Ablagerung der Kössener Schichten ihren Höhepunkt. Im obersten Rhät ließ diese Schüttung nach und das terrigene Material konnte nur noch gelegentlich in die flachen Regionen gelangen, die mit dem Aufbau des Rhätoliaskalks entstanden waren. Die normale Ausbildung der Kössener Schichten ist im allgemeinen durch eine mehrere Meter mächtige Kalkbank, in die kleine Biol ithit-Linsen eingelagert sind, unterbrochen, durch die sie sich in eine Untere und Obere Wechselfolge gliedern lassen. Ihre Entstehung wurde wahrscheinlich durch eine kurzfristig geringere Absenkungsrate begünstigt. Die Entwicklung des Rhätoliaskalks setzte hier nicht gleichzeitig ein. Im nördlichen Teil begann sie sehr früh. Durch die hohe biogene Karbonat-Produktion, weitgehend in Form von Biohermen, und die dadurch bedingte starke Schüttung bioklastischen Materials dehnte sich die Rhätoliaskalk-Ausbildung nach Süden aus. Mit der entstehenden flachen Plattform bildete sich der gebankte Rhätoliaskalk aus, ein Wechsel zwischen massigen Riffschuttkalken und Einlagerungen terrigenen Materials. Zum Abschluß dieser Entwicklung kommt es zu einer kleinräumigen Fazies-Verzahnung zwischen Oolithen, Lumachellen und Algen-Stromatolithen. Im Gegensatz zu anderen Gebieten der Nördlichen Kalkalpen, wo eine Gliederung des Ablagerungsraumes in einen Beckenbereich und einen Rhätoliaskalk-Riffgürtels gegeben ist, liegt hier ein mehr oder weniger flaches Schelfgebiet vor. Eine Ausnahme stellt nur die Zürser Schwelle dar. Hierbei handelt es sich um ein die gesamte Zeit über persistierendes Hochgebiet. Die Gesteinsausbildung entspricht durchgehend der des Hauptdolomits. Im Vergleich zu anderen Bereichen des Sedimentationsraumes der bearbeiteten Gesteinsserien kann zusammenfassend gesagt werden, daß wir uns im Gebiet der Vorarlberger Kalkalpen zur Zeit der Obertrias am westlichen Ende der sich öffnenden Tethys befanden, und daß der Ablagerungsraum hier die nördliche Zone des zu dieser Zeit noch bestehenden oberostalpinen, epikontinentalen Flachmeer-Bereichs representiert.

    Description: Die Erdkruste und der obere Erdmantel Westeuropas sind in den letzten 30 Jahren intensiv durch refraktionsseismische Messungen erforscht worden. Die Daten und Ergebnisse sind in zahlreichen Arbeiten veröffentlicht worden. Abgesehen von einigen regionalen Zusammenfassungen fehlt bislang jedoch eine überregionale Gesamtdarstellung dieses umfangreichen Materials. Es ist das Ziel dieser Arbeit, die in zahlreichen Publikationen verstreuten Einzeldaten und Ergebnisse zu sammeln, unter einheitlichen Gesichtspunkten auszuwerten und die Ergebnisse in einer Reihe von Karten darzustellen. Aus verschiedenen Publikationen, Forschungsberichten und den Archiven des geophysikalischen Institutes der Freien Universität Berlin wurden insgesamt 360 Sei smogrammon tagen in reduzierter Form (V = 6 km/s) gesammelt.

    Description: In der vorliegenden Arbeit wurde ein numerisches Verfahren für die zweidimensionale Simulation stationärer Strömung in porösen Medien entwickelt. Dabei können Modelle mit anisotroper Permeabilität und Wärmeleitfähigkeit ebenso berechnet werden wie Modelle in geneigten und gekrümmten Gebieten. Das Verfahren basiert auf einer Finite-Differenzen-Methode mit einem Schema 2. Ordnung (Il'in-Schema). Für das nichtlineare Gleichungssystem wird ein Iterationsansatz mit einer Art Mehrgittermethode verwendet. Um den großen Anwendungsbereich des entwickelten Verfahrens zu demonstrieren, wird es auf zwei unterschiedliche Fragestellungen aus der Hydrothermik und der Schneemetamorphose angewendet.

    Description: Die vorliegende Arbeit beschäftigt sich mit Strati graphischen, paläontologischen und paläogeographischen Untersuchungen im Jura und in der Kreide des tansanischen Küstenstreifens im Hinterland von Dar-es-Salaam und Bagamoyo. Die Sedimentgesteine werden in sechs lithostratigraphische Einheiten gegliedert, von denen vier neu aufgestellt werden: Ngerengere-Formation (bisher Ngerengere-Sandstein; Unterjura-tiefes Aalenium), Ruvu-Formation (bisher Ruvu-Schichten; Mittel aal enium-Oberaaleni um), Lugoba- Formation (Bajocium-?Bathonium) , Malivundo-Formation (Callovium-Mitteloxfordium), Magindu -Formation (Callovium) und Chalinze-Formation (Unterkreide). Sieben Profile des Jura und der Kreide werden einzeln beschrieben und ihr Makro- sowie Mikrofossilinhalt angegeben. Mit Ammoniten werden in der Ruvu -Formation zwei biostratigraphische Zonen des Mittel- und Oberaalenium festgestellt (Murehisonae- und Concavum-Zone). In der Malivundo-Formation werden aufgrund von Ammoniten drei Zonen (Athleta-Lamberti- , Mariae-Cordatum und Transversarium-Zone} nachgewiesen. Der höchste Teil der Chalinze-Formation wird mit planktonischen Foraminiferen in die Globigerinelloides algerianus-Zone des Oberaptium gestellt. Korrelationen des Jura im Untersuchungsgebiet mit anderen Gebieten innerhalb Tansanias sowie mit anderen Gebieten in der indo-madagassischen Provinz werden durchgeführt. Dreiundzwanzig Ammonitenarten (sechs Familien) aus der Ruvu-, Malivundo- und Magindu-Formation sowie siebzehn Foraminiferenarten (sechs Oberfamilien), die aus der Malivundo- und Chalinze-Formation stammen, werden systematisch beschrieben. Fazies, Ablagerungsbedingungen und Tektonik werden diskutiert. Im Mittelaalenium-Oberaalenium, weiter nördlich erst im Bajocium erfolgt die Transgression nach W auf fluviatile Sedimente der Ngerengere-Formation bzw. auf das Kristallin. Im Hangenden des Oxfordium setzt mit erneuter Riffbildung eine regressive Phase im höheren Oberjura ein. Erst mit der Unterkreide erfolgt mit der Chalinze-Formation eine erneute Transgression. Die paläobiogeographischen Beziehungen der Ammoniten zu anderen Gebieten in der indo-madagassischen Provinz, zu Europa und Südamerika werden aufgezeigt. Unter Berücksichtigung sämtlicher bisher bekannter Fundorte der Mayaitiden-Gattungen ergibt sich, daß sie hauptsächlich auf die indo-madagassische Provinz beschränkt sind.

    Description: Kohlenstoff-Umsatz und -Bilanz des Bodens eines Buchenwald- Ökosystems auf Kalkgestein. Ziel der Arbeit war die Beantwortung der Frage, ob sich der C-Speicher Boden eines Kalkbuchenwald-Ökosystems im Zustand des Fließgleichgewichtes oder in einem auf- bzw. abbauenden Ungleichgewichtszustand befindet. Dazu wurden die CO2 -Abgaberaten des Bodens ,als Outputgröße mit einem Absaugverfahren, einer modifizierten Glockenme- thode und einem Partialdruck-Gradienten-Rechenansatz be- stimmt und dem C-Eintrag gegenübergestellt. Die CO2 Abgaberaten des Bodens schwankten zwischen 20 (Winter) und 300 mg CO2 .m-2.h-1 (Sommer). Die Beziehung zwischen der Höhe der C02 -Abgaberate, der Temperatur und dem Wassergehalt des Bodens ließ sich in einer multiplen line- 2 aren Regressionsgleichung darstellen (r ≈0.80). Einem C-Eintrag von 282 g.m-2 .a-1standen C-Verluste von )06 g.m- .a- gegenüber. Der Differenzbetrag wurde auf die Wurzelatmung der Bäume zurückgeführt. Die C-Bilanz des Bo-dens erscheint somit ausgeglichen. Die rechnerischen Antei- le des Streufalles, der Wurzelstreu und der Wurzelatmung an der Gesamt-C02 -Abgabe des Bodens liegen bei 61, 31 und 8%. Durch Messungen der C02 -Konzentrationen der Gasphase im Solum und anstehenden Gesteinsverband konnten wertvolle Erkenntnisse über die ökologischen Eigenschaften des Standortes gewonnen werden. So liegen die CO2 Konzentrationen im Waldboden mit max. 0.8 Val. %deutlich unter den Werten ackerbaulich genutzter Standorte. Die gegen Ende des Untersuchungszeitraumes in 100 - 250 cm Tiefe des aufgelockerten Kalksteinverbandes gemessenen C02 Partialdrücke stimmen mit den anhand von Sicker- und Quell wasseranalysen errechneten Gleichgewichts-C02 Partialdrücken überein.

    Description: The lipids and kerogens of 15 sediment samples from Site 547 (ranging from Pleistocene to Early Jurassic/Triassic) and 4 from Site 545 (Cretaceous) have been analyzed. A strong terrestrial contribution of organic matter was found, and significant autochthonous inputs were also present, especially at Site 545. Both strongly reduced and highly oxidized sediments have been found in the Cenozoic and Jurassic samples of Site 547. On the contrary, all the Cretaceous sections of Sites 547 and 545 are anoxic. Sediments from anoxic paleoenvironments are immature and have a high content of sterenes, diasterenes, steradienes, hopenes, and ßß hopanes. Samples from oxic paleoenvironments are mainly mature and their content of hopenes and steriod structures is below the detection level. Nevertheless, their hopane distributions have the immature ßß homologs as the predominant molecular markers. For Site 545 the most abundant molecular markers are ring A monoaromatic steranes, and their presence is attributed to microbial and chemical transformations during early diagenesis.

    Description: Manganese nodules occurring within marine sediments of presumably Upper Miocene-Lower Pliocene age from cores obtained by the Argentine oceanographic vessel ARA Islas Orcadas in 1977 on the Malvinas (Falkland) Plateau and neighbouring Scotia Sea were studied with the aim of comparing them with other fossil nodules found on the mainland of Argentina that were also ascribed to the marine environment. After optical mineralogical, chemical, X-ray and trace element analysis, the studied "nodules" proved to be actually wacke clasts cemented by manganese oxides with a high Fe/Mn ratio corresponding to a continental environment. The studied "nodules" thus differ from the Argentine mainland nodules and are supposed to have been transported from continental environments and then deposited in the marine realms. The wacke clasts became then nuclei for the deposition of the marine manganese oxides of the coatings. The proportion of trace elements, which is high, suggests the growth of the nodules in the marine environment.

    Description: Morphological, mineralogical and chemical analysis are reported for a metalliferous encrustation from a seamount in the Gulf of Guinea, South Atlantic. The results are compared with published data on encrustation from similar environments. The morphology and mineralogy indicate a crust formed on the exposed rock surface with some agglutination of foram debris. Comparison of the abundance patterns for transition elements with that of known data suggests that some enrichment had resulted from the high primary productivity at this site.

Previous cruises (Discovery 118, 126, 134 and Farnella 3/81) had done much of the ground work, consequently the area was already well known but not necessarily well understood for the purposes of our investigation.

    Description: The drilling plan for Leg 74 of the Deep Sea Drilling Project was designed to address three main scientific topics: (1) the history of the deep-water circulation in the southeastern Atlantic, (2) the nature and geologic evolution of the Walvis Ridge, and (3) the biostratigraphy and magnetic stratigraphy of this region. In order to study these subjects, a suite of five sites was drilled on the Walvis Ridge that extended from its crest (near 1000 m water depth) down its northwest flank into the Angola Basin to a depth of 4400 m.

    Description: Leg 73 was the middle of five legs on South Atlantic paleoenvironments planned by the JOIDES Ocean Paleoenvironment (OP) Panel during the years from 1975 to 1980. The idea of drilling a transect of holes across the 30°S parallel was entertained soon after the drilling on Leg 3, during the first phase of the Deep Sea Drilling Project (1968/69), when the surprising discovery was made that the middle Miocene sediments of the South Atlantic were largely marls and red clays. The deposition of the red clays was obviously related to the intense dissolution of calcite during the middle Miocene, when the calcite-compensation level was elevated. The objectives and tactical planning for a transect across the east flank of the Mid-Atlantic Ridge just north of 30°S were outlined by the OP Panel more fully to the Planning Committee in July of 1978. After a piston core containing Paleocene sediments was taken in 1979 at the site in the Cape Basin at the foot of the Walvis Ridge this area was designated for DSDP Leg 73 and 74.

    Description: Site 530 is located in the southeastern corner of the Angola Basin, about 20 km north of the Walvis Escarpment, near the eastern end of the easternmost (or Frio) segment of the Walvis Ridge. It lies on the abyssal floor of the Angola Basin and exhibits a seismic stratigraphic sequence typical for the entire deep part of the basin. It was selected because it appears to have the oldest strata in the region preserved in a sediment pond between low basement rises.

    Description: The drilling of Leg 77 is part of an overall program by the JOIDES Passive Margin Panel to study the evolution of the western North Atlantic passive margin. The history of the central North Atlantic is probably the best known of all ocean basins, but the origin and history of the neighboring Gulf of Mexico are very much uncertain. Some geologists consider it the oldest ocean basin still in existence (Paleozoic), but others doubt the existence of "true" oceanic crust under the central Gulf. The nature and origin of the transitional crust and the overlying Mesozoic sedimentary sequences in the southeastern Gulf, therefore, was the main objective of Leg 77.

    Description: Analyses of the bulk oxidation state of marine manganese nodules indicates that more than 98% of the Mn in deep ocean nodules is present as Mn(IV). The samples were collected from three quite different areas: the hemipelagic environment of the Guatemala Basin, the pelagic area of the North Pacific, and seamounts in the central Pacific. Results of the study suggest that todorokite in marine nodules is fully oxidized and has the following stoichiometry: (K, Na, Ca, Ba)0.33 (Mg, Cu, Ni)0.76 Mn5 O22 (H2O)3.2.

    In:  Supplement to: Calvert, Stephen E; Piper, David Z (1984): Geochemistry of ferromanganese nodules from DOMES site a, Northern Equatorial Pacific: Multiple diagenetic metal sources in the deep sea. Geochimica et Cosmochimica Acta, 48(10), 1913-1928, https://doi.org/10.1016/0016-7037(84)90374-0
    Publication Date: 2023-08-28
    Description: The major and minor element composition of ferromanganese nodules from DOMES Site A has been determined by X-ray fluorescence methods. Three phases appear to control the bulk compositions: Mn and Fe oxyhydroxides and aluminosilicates. Relatively wide compositional variations are evident throughout the area. Nodules with high Mn/Fe ratios, high Cu, Mg, Mo, Ni and Zn concentrations and high todorokite/-MnO2 ratios have gritty surface textures and are confined to an east-west trending depression with thin Quaternary sediment cover. Nodules with low Mn/Fe ratios, high concentrations of As, Ca, Ce, Co, La, P, Sr, Ti, V, Y and Zr and low todorokite/-MnO2 ratios have smooth surfaces and are confined to shallower areas with relatively thick Quaternary sediment to the north and south of the depression. All nodules in the area have compositions which are influenced by diagenesis, but those with the most marked diagenetic signature (high Mn/Fe and Cu/Ni ratios, low Ce/La ratios and more todorokite) are found in areas of very slow or non-existent sedimentation; many of these nodules are actually in contact with outcropping Tertiary sediment. This paradox may be resolved by postulating, by analogy with some shallow-water occurrences, that the nodules accrete from bottom waters which have enhanced particulate and dissolved metal contents derived from diagenetic reaction in areas remote from the site of nodule formation. The metals are supplied in a bottom flow (probably Antarctic Bottom Water) which also erodes, or prevents modern sedimentation in, the depression. Nodules on the flanks of the depression are not evidently affected by this flow and derive at least pan of their constituent metals from diagenetic reaction in the underlying Quaternary sediment. Apparently, abyssal diagenetic nodules can have an immediate and a remote diagenetic metal source. Metal fluxes derived from pore water dissolved metal gradients may not be relevant to particular accreting nodules if a significant fraction of their metals is derived from outside the area in which they form.

    In:  Supplement to: Smith, J N; Schafer, C T (1984): Bioturbation processes in continental slope and rise sediments delineated by Pb?210, microfossil and textural indicators. Journal of Marine Research, 42(4), 1117-1145, https://doi.org/10.1357/002224084788520738
    Publication Date: 2023-08-28
    Description: Measurements of Pb-210 activities, in conjunction with micropaleontological, geotechnical and sedimentological observations, on sediment cores have been used to characterize two distinctive bioturbation regimes on the continental slope and rise east of Newfoundland. On the rise (2600 m), excess Pb-210 is confined to the upper few centimeters of the coarser-grained sediments underlying the axis of the Western Boundary Undercurrent. The geological and geochemical evidence for a low rate of bioturbation in this high bottom current regime is consistent with a reduced population of deeper burrowing macrofauna, particularly the species Maldane sarsi. In contrast, a higher flux of organic-rich, fine-grained particulate material to the middle slope (1500 m water depth), and the comparatively stable sedimentological conditions that prevail in this low bottom current regime, have led to the active colonization of the sediment substrate by bioturbating organisms. Enhanced mixing of middle slope deposits is reflected by comparatively lower shear strengths within the upper 30 cm of the sediment column, and by the reduced variability of the sediment-depth distribution of the most abundant species of foraminifera. Excess Pb-210 has been transported downward from the sediment-water interface to depths greater than 12 cm. Some Pb-210 profiles from the middle slope can be interpreted in terms of a diffusion mixing model for which the biological mixing coefficients are of the order of 0.10-1.0 cm2/yr.Measurements of the two and three dimensional distribution of excess Pb-210 in one middle slope box core indicate that the mixing process in these sediments has a pronounced heterogeneous component on time scales of the same order as the half life of Pb-210 (22.3 yr). Spatial correlations between Pb-210 anomalies and artifacts of bioturbation observed in x-radiographs of the core suggest that Pb-210 maxima observed at depth may be the result of an inclined orientation of burrow structures which have introduced a significant lateral component to the downward transport of surficial sediments.

    Publication Date: 2023-08-28
    Description: Relationships among Th and Ra isotopes in nodule, sediment and water phases at MANOP Site S establish the most likely source for Th in the nodules, the frequency of nodule turning, and the similarity of micro and macro nodules. Manganese nodules and bottom waters have 230Th/232Th activity ratios considerably higher than other phases at this site suggesting that sea water is the likely source of Th for the nodules. Similar 230Th/232Th activity ratios in nodule tops and bottoms and in certain cases departure from expected 226Ra/230Th activity ratios in nodule tops and bottoms indicate that the nodules rotate every one to ten thousand years. The micro nodules have diffusion coefficients of Ra similar to macro nodule bottoms. I suggest that they may act as a carrier phase for transporting metals through oxic sediments to nodules.

    Publication Date: 2023-08-28
    Description: Ferromanganese micronodules have been found on Georges Bank, off the U.S. northeast coast, distributed throughout the surficial sediments within an area about 125 km long and at least 12 km wide. These coarse, sand-sized concretions have precipitated from metal-rich interstitial waters and contain many of the textural and structural features common to other neritic nodules. Most of the nodules have accreted around detrital grains, and X-ray powder diffraction analyses indicate the presence of geothite and vernadite ( delta -MnO sub(2)) in the ferromanganese layers. Chemical analyses of the micronodules, when compared with similar data on deep-sea manganese nodules, reveal lower Mn/Fe ratios, significantly higher concentrations of V and As, comparable values of Mo, and an order of magnitude less of Co, Ni, Ce and most other, metals.

    Publication Date: 2023-07-24
    Description: We analyzed the oxygen and carbon isotopic composition of planktonic and benthic foraminifers picked from 13 late Eocene to late Oligocene samples from DSDP Site 540 (23°49.73'N, 84°22.25'W, 2926 m water depth) from the Gulf of Mexico. An enrichment occurs in 18O of about 0.5 to 0.8 per mil in both benthic foraminifers and surface-dwelling planktonic foraminifers between the latest Eocene and early Oligocene. This early Oligocene maximum is followed by lower 18O values. A 1.2 per mil d13C decrease in both benthic and planktonic foraminiferal data occurs from the late Eocene to the late Oligocene. There is a correspondence of the 13C signal to deep-sea records; however, the amplitude of this change is greater than previously seen in deep-sea cores, possibly as a result of proximity to terrestrial sources of carbon. The covarying isotopic changes in both benthic and planktonic foraminifers suggest global causes, such as ice volume increases and increased terrestrial carbon input to the ocean. However, during the latter part of the record (early-late Oligocene), the increases in the benthic 18O without accompanying increases observed with planktonic foraminifers suggest that changes in only one part of the system occurred; one potential explanation being a decrease in bottom-water temperatures without concomitant changes in the surface waters. The 18O differences between species of planktonic foraminifers and the difference between planktonic and benthic 18O data indicate that diagenesis problems are minimal. These preliminary results are encouraging given that these cores are partially lithified.
