    Description: Die vorliegende Arbeit behandelt die Kalkdinoflagellaten-Floren aus dem Alb der Forschungsbohrung Kirchrode II (Niedersächsisches Becken). Im Vordergrund stand die Frage nach der bisher wenig bekannten Ökologie dieser Phytoplankton-Gruppe zur Zeit ihrer maximalen Blüte. Dazu wurden die Zysten-Vergesellschaftungen qualitativ und halb-quantitativ untersucht und Diversitätsanalysen durchgeführt. Die Ergebnisse wurden mit lithologischen und paläontologischen Daten der an der Untersuchung des Bohrkerns beteiligten Arbeitsgruppen verglichen. Es konnten 37 Morphospezies kalkiger Dinoflagellaten-Zysten nachgewiesen werden. Gemeinsam mit den Morphospezies des Profils Kirchrode I erhöht sich damit die Gesamtzahl der im Alb des Niedersächsischen Beckens nachgewiesenen Taxa auf 45. Das weltweit früheste Auftreten der Unterordnung Pithonelloideae konnte für das frühe Mittel-Alb (Hoplites dentatus-Zone) belegt werden. Außerdem konnte erstmals die Verbreitung der Fuettererelloideae für die Unterkreide sicher dokumentiert werden. Aufgrund unterschiedlicher ökologischer Umweltansprüche konnten 4 typische Kalkdinoflagellaten-Gesellschaften unterschieden werden. Die Zusammensetzung der Zystenvergesellschaftungen wird in erster Linie von Nährstoffreichtum, Salinität und Temperatur des Oberflächenwassers kontrolliert. Gemeinsam mit den neu interpretierten Kalkdinoflagellaten-Vergesellschaftungen des Profils Kirchrode I (KEUPP 1995) reflektieren die Vergesellschaftungen für das Unter- und Mittel-Alb einen Meeresspiegelanstieg bei gleichzeitiger Nährstoffverarmung und Erwärmung. Für das Ober-Alb kann ein Meeresspiegelhöchststand (maximale Pelagizität) und anschließende rasche Regression postuliert werden. Daten anderer Fossilgruppen (Coccolithophoriden, Foraminiferen, Radiolarien) untermauern diese Interpretation. Die Palökologie der Unterkretazischen Orthopithonelloideae wird neu interpretiert. In der späten Unterkreide sind sie nicht, wie bisher angenommen, pelagisch, sondern im Gegenteil an trophische, neritische und vermutlich auch kühlere Oberflächenwasser-Bedingungen gebunden. Innerhalb der grobkristallinen Vertreter der Pirumella loeblichi-Gruppe nimmt P. loeblichi aufgrund abweichender ökologischer Ansprüche (Präferenz für stagnierende und nährstoffreichere Beckenbedingungen) eine Sonderstellung ein. Es konnten 6 Migrationsereignisse tethyaler Zysten nachgewiesen werden, die vermutlich transgressive Impulse widerspiegeln. Die auf diese Fossilgruppe erstmals angewendeten Methoden der Diversitäts- und Häufigkeitsanalysen haben sich als geeignet erwiesen, Wechselwirkungen zwischen fossilen Kalkdinoflagellatenzysten und ihrer Umwelt aufzuzeigen.
    Description: Subject of this study are the calcareous dinoflagellates cysts of the drilling core Kirchrode II (Albian, central Lower Saxony Basin, Northwest Germany). The purpose of this investigation is to give answers to the question of the poorly understood palaeoecology of this important phytopankton group at the time of its maximum radiation. Cyst assemblages were examined qualitatively and semi-quantitatively. Diversity analyses of the cyst assemblages were carried out as well. The results were compared with other lithological and palaeontological data of the drilling core. 37 morphotaxa were identified. Together with the morphospecies recorded from the uppermost Upper Albian of the drilling core Kirchrode I (KEUPP 1995), the number of documented taxa in the Albian of the Lower Saxonian Basin increases to 45 taxa. The first appearance date of the suborder Pithonelloidae is recognised in the lower Middle-Albian (Hoplites dentatus-zone). Moreover, the distribution of the Fuettererelloideae in the Lower Cretaceous is documented for the first time. The taxonomic compositions of the cyst assemblages change through time. Due to their different ecological preferences, 4 typical cysts-assemblages were recognised. The composition of the assemblages was controlled chiefly by nutrient availability, salinity and temperature of the surface water-masses. Together with the re-examined cyst-assemblages of the drilling-core Kirchrode I, the assemblages reflect a sea level rise during the Early and Middle Albian, together with simultaneous warming and nutrient decrease. A postulated sea level highstand (maximum pelagicity) in the Late Albian is followed by a rapid regression in the upper dispar-zone. Data from other plankton groups (coccolithophorids, foraminiferes and radiolarians) support this interpretation. The palaeoecology of the Early Cretaceous Orthopithonelloideae is newly interpreted. They were not, as supposed until now, components of the pelagic realm. On the contrary, their distribution reflects neritic, nutrient-rich and probably cool surface-water masses. Within the Obliquipithonelloids with coarse-crystalline body walls, Pirumella loeblichi holds an exceptional position with respect to its deviating ecology (preference for stagnant and nutrient-rich basin conditions). 6 distinct migration-events of cysts with tethyal origin were recognised. These events are probably related to transgressive pulses. The methods of community and diversity analyses, used for the first time for this little known phytoplankton group, are a powerful tool for the analyses of paleoecological distribution patterns of the group and can be used for paleooceanic basin interpretation.

    Description: Am Westrand des Basko-Kantabrischen Beckens (Soba-Region, Prov. Cantabria, Nordspanien) sind die Plattform/Becken-Übergangszonen des Apt und Alb in nahezu ungestörtem Verband erhalten. Entlang dieser Randzonen befinden sich großdimensionierte Mud Mound-Strukturen mit einer Basisbreite bis 150 m und einer Höhe bis zu 70 m. Diese Arbeit zielt auf die Erarbeitung der Prozesse, die die Bildung der Mounds begleiten, beeinflussen oder steuern. Das Intervall Oberapt (Clansay) bis Mittelaib besteht aus sechs sedimentär-diagenetischen Zyklen (asymmetrische Trans-, Regressionszyklen), die in Kombination mit Markerhorizonten eine stratigraphische Kontrolle über den Plattform/Becken-Transekt ermöglichen. Meeresspiegelschwankungen (Paläokarst) sind im Apt/Alb-Grenzintervall und hohen Unteralb (Ammonitenzone: Douvilleiceras mammilatum) nachweisbar. Die Vorkommen der Mud Mounds sind an transgressive Faziesdiskontinuitäten gebunden. Ihre Position entspricht dem zu Strömungen exponierten Hang und dem oberen Plattformrand. Die Biofazies reicht von einer aphotischen Gemeinschaft aus “Lithistida“, Hexactinellida, krustosen Foraminiferen, Polychaeten, Thecideen und Acanthochaeteten zu der photischen Biofazies mit Scleractinia, Lithophyllum und Bacinella/Lithocodium. Die Strukturbildung erfolgt durch eine autochthone Mikritproduktion (Automikrit). Akkretionäre Automikrite bilden Stromatolithe, Thrombolithe und massive Gefügetypen. Container-Automikrit befindet sich in geschützten und geschlossen Räumen. Kieselschwamm Container-Automikrite sind aphanitisch, peloidal und peloidal-bakterioform. Unabhängig von Kieselschwämmen treten Container-Automikrite in Kleinhöhlen, Taschen und im Interpartikelvolumen auf. Sie bestehen aus in-situ Peloiden und in-situ Ooiden mit massivem und/oder stromatolithischem Gefüge. Die verschiedenen Automikrittypen besetzen zwischen 50 und 80 Vol.-% der Mud Mounds. Anbohrungen durch lithophage Bivalven und Aka sowie die ausschließliche Produktion angularer Mound-Lithoklasten belegen eine Lithifizierung in statu nascendi. Die Primärmineralogie der Automikrite ist Hoch-Mg-Calcit; die Residualgehalte an MgCOa liegen zwischen 1 ,2 und 3,6 Mol-%. Die Zusammensetzung der stabilen Isotope S13C und S18O (vs PDB) ist analog zu anorganisch gebildeten, marinen Zementen (513C von 2,9 bis 3,8 und S18O von -1,5 bis -4). Die vergleichende Aminosäuren-Analyse ergibt ein relatives Maximum bei Glu und Asp, Pyruvaten und Glycin, resp. Tyrosin. Das Spektrum ist analog zu den Literaturdaten von modernen Automikriten aus Riffhöhlen von Lizard Island (GBR) und unterscheidet sich grundlegend von den strukturgebundenen Skelett-Automikriten von Bacinella/Lithocodium. Die Biomarker-Analyse akkretionärer Automikrite ergab ein spezifisches n-Alkan Muster, ebenfalls vergleichbar mit Spektren rezenter Thrombolithe (Lizard Island) und Beispielen der oberjurassischen Spongiolith-Fazies. Die Grundvoraussetzung der Mud Mound-Genese ist daher die Bereitstellung saurer Makromoleküle (Organomikrit) und eine anhaltend ungestörte Wechselwirkung mit dem umgebenden Medium. Die chemische Randbedingung ist eine erhöhte Karbonatalkalinität. Nach mikrofaziellen Kriterien ist Organomikrit ein faziesbrechendes Element der unterkretazischen Plattformränder. Beispiele reichen von karbonatischen Barrensanden mit Organomikrit-Rindenkörnern, über deltaische Sandsteine (Organomikrit um Quarz) bis zu Kondensationshorizonten auf Paläokarst sowie Drowning-Sequenzen auf Korallenpflastern (Sclercatinia zu Kalkalgen zu Thrombolith). Die Bildung der Mud Mounds (Organomikrit-Riffe) der Soba-Region ist korreliert mit einer regional extrem herabgesetzten Karbonatproduktion. Diese durch terrigenen Input und mögliche Eutrophierungen verursachten Produktionskrisen setzten die relativ uneffektive Organomikritproduktion in Vorteil gegenüber den stenoöken Gemeinschaften der euphotischen Zone. Die erhöhte Karbonatalkalinität kann von der Zufuhr der Verwitterungslösungen (regional) und dem Abau organischer Substanzen abgeleitet werden (lokal, Sulfatreduktion). Möglicherweise bestand ein Zusammenhang mit der Auslaugung von Keuperdiapiren.
    Description: At the western margin of the Vasco-Cantabrian Basin (Soba-Region, Prov. Cantabria, N-Spain) the primary facies architecture of the Aptian-Albian platform/basin transition is well preserved. Along these zones large-scaled mud mounds reach 70 meters in height with a basal diameter of up to 150 meters. Aim of this work is to point out processes that are limited to coexistance and such that influence or even control mud mound formation. The Upper Aptian (Clansayesian) to Middle Albian interval consists of six sedimentary-diagenetic cycles that represent asymmetric transgressive/regressive facies sequences. In combination with marker horizons these cycles provide a stratigraphic control across the platform/basin transition. Sea-level changes recorded as paleokarst are documented in the Aptian/Albian boundary interval and within the upper parts of the Lower Albian (ammonite zone: Douvilleiceras mammilatum). Mud Mounds follow transgressive discontinuities of facies. These structures are both located at slopes facing wave-induced current systems and at the upper platform margin. The involved biofacies include an aphotic community with lithistid demosponges, hexactinellids, encrusting foraminifera, polychaetes, thecidean brachiopods and acanthochaetetids as well as a photic community with scleractinian corals, calcareous algae such as Lithophyllum and the problematic structure of Bacinella/ Lithocodium. Mud mounds are constructed by autochthonous production of micrite (automicrite). Accretionary automicrites form stromatolites and thrombolites as well as massive fabrics. Container-automicrite is restricted to protected and closed spaces. Container-automicrites of siliceous sponges reveal aphanic, peloidal and peloidal-bacterioform microfabrics. However, container-automicrite may also occur within minicaves, pockets and the interstitial space of rudstones lacking any sponge evidence. These automicrites consist of in-situ peloids and in-situ ooids forming massive and/or stromatolitic microfabrics. All automicrites, variously developed, hold 50 to 80 % of the total mud mound volume. Borings by lithopagous bivalves and sponges (Aka) and additionally the exclusive occurrence of angular mound lithoclasts provide evidence for lithification in statu nascendi. The primary mineralogy of the automicrites is high Mg-calcite with residual MgCOa-contents between 1.2 and 3.6 mole-%. The composition of stable isotopes (S13C and S18O vs. PDB) goes along with inorganically precipitated marine cements (813C: 2.9 to 3.8, S18O: -1,5 to -4). The comparative analysis of amino acid quantity reveals relative maxima of glutamin and asparagin, pyruvates and glycin as well as tyrosin. The relative amounts of amino acids are very similar to those obtained from modern automicrites of Lizard Island reef caves (GBR) and are clearly seperated from skeletal automicrites of Bacinella/ Lithocodium. In addition, biomarker analysis of accretionary automicrites resulted in a specific n-alkane pattern comparable to literature data of modern marine thrombolites (Lizard Island) and Upper Jurassic spongiolites. According to these results, the basic neccessity for mud mound genesis is the occurrence of acidic macromolecules producing a specific automicrite (organomicrite) and their persistent interaction with thesurrounding medium. Chemically, an increased carbonate alkalinity is required. Thin section analysis provides evidence that organomicrite is a widespread element of Lower Cretaceous platform margins overlapping different facies zones. These include carbonate shoal sediments with organomicrite-coated grains and deltaic sandstones with organomicrite-coated quartz grains. Further examples are intervals of stratigraphic condensation overlaying paleokarst or drowning sequences following a succession from scleractinian corals towards calcareous algae and thrombolites. On the regional scale mud mounds (organomicrite reefs) of the Soba-Region correlate with times of drastically reduced carbonate production. This, potentially caused by terrigenous input and episodes of eutrophism, leads to a dominance of the relatively ineffective production of organomicrite over the highly productive stenotopic (euphotic) communities. An increase of carbonate alkalinity can be deduced from regional scale continental weathering and from sulfate reduction on local scale. Possibly, a correlation between brines of subsoluted diapirs (Keuper) and the formation of automicrites might have existed.

    Description: In der vorliegenden Arbeit wird - basierend auf externmorphologischen Kriterien von Brachiopodengehäusen aus dem spongiolithischen süddeutschen Oberjura - eine ökologische Interpretation von Brachiopodenassoziationen vorgestellt und diese mit nicht verschwammten Vorkommen unter Verwendung verschiedener methodischer Ansätze verglichen. Aus insgesamt elf brachiopodenführenden Lokalitäten unterschiedlicher stratigraphischer und fazieller Niveaus wurden die generell bevorzugt auftretenden Wuchsformen ermittelt, zu Standardmorphotypen zusammengefaßt und mit digitalisierten Abbildungen aus vorhergehenden Bearbeitungen ökologisch verglichen. [ …] [ … Tabelle 1. Stratigraphie, Fazies und dominierende Externmorphologie der Brachiopodengehäuse (Standardmorphotyp) in den untersuchten Lokalitäten.] Die Analysen ergaben, daß mit Hilfe des Verlaufs der dorsalen Umrißlinie, dem Verlauf der Frontalkommissur und untergeordnet der Foramengröße eine hinreichende Interpretation des Environments hinsichtlich Substratbeschaffenheit, Hydrodynamik und Bathymetrie erfolgen kann. Die wichtigsten Ergebnisse sind: a) Die Brachiopoden der süddeutschen Spongiolithfazies zeigen im Vergleich mit je einer Fauna aus einer schwach verschwammten Schichtfazies, einer Korallenfazies und einer oolithischen Mergelkalkfazies grundlegende Unterschiede in der äußeren Morphologie ihrer Gehäuse, b) In mergeldominierten Lokalitäten sind die Sphärizitätsindizes der Gehäuse deutlich höher als in der Korallenfazies, c) Reduzierte Werte des Dicken / Breiten - Verhältnisses scheinen ein Indiz für weichere Substrate zu sein, d) Im zeitlichen Verlauf (Oxfordium bis Unter-Tithonium) nehmen die Werte der Sphärizitätsindizes der Brachiopodengehäuse ab. e) Die Amplituden der Frontalkommissuren von Brachiopoden aus dem Moundbereich sind höher als diejenigen aus der Korallenfazies, f) Das Mengenverhältnis von terebratuliden zu rhynchonelliden Brachiopoden läßt Rückschlüsse auf das dominierende Substrat in den Moundbereichen zu. Ein quantitatives Übergewicht rhynchonellider Brachiopoden geht mit einem mergelreichen, stillen Tieferwasserenvironment einher, während die kalkdominierten Flachwasserbereiche mit erhöhter Hydrodynamik bevorzugt von Terebratuliden besiedelt werden, g) Untergeordnet wird ein Substratwechsel durch die Foramengröße und -position angezeigt. Große mesothyridide Foramina kennzeichnen meist Festsubstrate. Kleine hypothyridide Foramina sind eher für allomikritische Bereiche charakteristisch, h) Brachiopoden der koralligenen Fauna zeichnen sich durch Asymmetrien der Frontalkommissur (Rhynchonellida) und Asymmetrien in der dorsalen Umrißlinie aus (Terebratulida). Die artikulaten Brachiopoden aus den untersuchten „Riff-Ablagerungen scheinen hinsichtlich ihrer Morphologie und faunistischen Komposition von den kontrollierenden Bildungsfaktoren (besonders Sedimentationsrate, Substratbeschaffenheit und Hydrodynamik) der Schwamm- und Korallenassoziationen, beeinflußt worden zu sein. Die in den jeweiligen Aufschlüssen dominierenden Brachiopoden-Morphotypen reflektieren wenigstens statistisch die Bildungsbedingungen.
    Description: Data on brachiopods in spongolites from the Upper Jurassic of southern Germany were collected in order to establish associations based on paleoenvironmental parameters and compare these results to similar fauna across a range of depositional paleoenvironments. Fossils were sampled and their dominant growth morphotypes identified from 11 localities representing different ages and facies of the Upper Jurassic in the Franconian and Swabian Alb. These growth morphotypes were compared to standard morphotypes and to biometric data of modern brachiopods gleaned from the literature. Through statistical analysis, it was found that the mode of commissure line and in part the diameter of the foraminae correlate well with substrate types and hydrodynamic to bathymetric paleoconditions. General results include: a) the external morphology of brachiopods from spongolites is significantly different from that of brachiopods from well-bedded limestone containing few to no sponges but corals and oolites, b) within a mostly marl substrate, the sphericity index of brachiopod shells is much larger than for shells in coral-bearing rocks, c) width to length ratios of shells are less for softer substrates indicating possible use as an index for substrate consistency, d) from the Lower Oxfordian to the Tithonian, the sphericity index of shells in general decreases, e) amplitudes of the frontal commissure line of brachiopods found within spongolite build-ups are much larger than those from coral-bearing rocks, f) Terebratulidae to Rhynchonellida biometric relations may be used as an index for judging the “quality” of the paleoenvironment; rhynchonellid brachiopods were dominantly found in marly, deeper paleoenvironments, whereas carbonate sediments deposited under shallow, high energy, water paleoconditions were colonized by terebratulid brachiopods, g) the size and position of foraminae are linked to the substrate type; brachiopods with larger mesothyrid foraminae are found associated with hard substrates while smaller hypothyrid foraminae in soft carbonate sediment areas, h) brachiopods from coral rocks are characterized by their asymmetric growth in form (Terebratulida) and of their frontal commissure (Rhychonellida). In general, brachiopods from reefal deposits appeared to have been directly influenced morphologically by paleoecologic factors, such as sedimentation rate, substrate type, and water energy levels. The dominant standard morphotype of brachiopods appears to correlate in a statistically significant way with the interpreted depositional circumstances at each locality. Due to here presented morphological data of brachiopodes from the Upper Jurassic of Southern Germany, associations of brachiopodes in spongiolites are interpreted palecologically and compared to similar faunae from other depositional environments. From 11 localities of different stratigraphical age and facies in the Franconian and Swabian Alb the dominant growth morphotypes are presented and abstracted to so-called „standard morphotypes“. The latter are compared to biometrical data of modern brachiopodes, mainly extracted from literature data. Interpreting the mathematical analyses it can be concluded that the dorsal outline, the mode of commissur line and partially the diameter of the foraminae can be used as indicator of substrates, hydrodynamical and paleobathymetrical conditions. The main results are: a) External morphology of brachiopodes from spongiolites exhibits strong differences in contrast to brachiopodes from well-bedded limestones with few or no sponges, to coral-bearing strata and to oolithic limestones, b) In localities, where marls have been predominantly deposited, the sphericity index is much larger than in the coral-bearing rocks, c) Reduced relations of width and length can be tentatively used as index for soft substrates, d) From the Lower Oxfordian to the Tithonian the sphericity index becomes smaller, e) Amplitudes of the frontal commissur line from brachiopodes of spongiolitic buildups are much higher than from brachiopodes in coral-bearing rocks, f) Quantitative relations from Terebratulidae to Rhynchonellida can be used as index for quality of substrates. Rhynchonellid brachiopodes are dominating marly, deeper environments, whereas carbona-tic sediments deposited under shallow water conditions with higher water energy are dominated by terebratulid brachiopodes. g) Changes of substrates are indicated by the size and position of foraminae. Larger mesothyrid foraminae characterize hard substrates, smaller hypothyrid foraminae are typically developed in allomicritic areas, h) Brachiopodes from coralligene rocks are characterized by their asymmetrical growth of form (Terebratulida) and of their frontal commissure (Rhynchonellida). Generally, brachiopodes from reefal deposits have been influenced morphologically by ecologically controlling factors such as the sedimentation rate, the substrate, and the water energy levels. The dominating standard morphotypes of brachiopodes in each locality reflect at least statistically the former depositional environments. (Translation: Dr. Elizabeth H.
