    Lead isotope ratios of basalts from DSDP Leg 37 (Table 1) (1976)

    Description: Analyses of Pb from mid-ocean ridge basalts obtained from DSDP Leg 37 lie on a line of near-zero-age slope. The data seem consistent with an evolutionary model of three stages, the beginning of the second stage being at about 600 m.y. - the model age obtained for the least radiogenic Pb. The beginning of the third stage of evolution at the time of formation of the rocks apparently did not change the average Th/U ratio since measured values are consistent with the ratio deduced from Pb isotope ratios. Ratios of U/Pb are not consistent with Pb isotope ratios, however, thus ruling out a simple two-stage evolutionary model.

    The distribution of sulfur in oceanic crust with respect to oxidative diagenesis (Table 1) (1979)
    PANGAEA
    In:  Supplement to: Andrews, Anthony J (1979): On the effect of low-temperature seawater-basalt interaction on the distribution of sulfur in oceanic crust, layer 2. Earth and Planetary Science Letters, 46(1), 68-80, https://doi.org/10.1016/0012-821X(79)90066-9

    Description: A detailed geochemical-petrological examination of layer 2 basalts recovered during Leg 37 of the DSDP has revealed that the original distribution, form and abundance of igneous sulfide have been profoundly altered during low-grade oxidative diagenesis. The net result appears to have been a rather pervasive remobilization of igneous sulfide to form secondary pyrite accompanied by a bulk loss of sulfur equivalent to about 50-60% of the original igneous value, assuming initial saturation. It is suggested that during infiltration of seawater into the massive crystalline rock, igneous sulfide has experienced pervasive oxidation, under conditions of limited oxidation potential, to form a series of unstable, soluble sulfur species, primarily in the form of SO3[2-] and S2O3[2-]. Spontaneous decomposition of these intermediate compounds through disproportionation has resulted in partial reconstitution of the sulfur as secondary pyrite and the generation of SO4[2-] ion, which, due to its kinetic stability, has been lost from the basalt system and ultimately transferred to the ocean. This model not only satisfies the geochemical and petrological observations but also provides a suitable explanation for the highly variable delta34S values which characterize secondary sulfides in deep ocean floor basalts.

    Annotated record of the detailed examination of Mn deposits from DSDP Leg 37 (Holes 332B, 334) (1977)
    PANGAEA
    Details
    Publication Date: 2024-05-15
    Description: DSDP Leg 337 was planned as an attemp at deep penetration of the igneous section of the oceanic crust on the western flank of the FAMOUS (Franco- American Mid-Ocean Undersea Study) area of the Mid-Atlantic Ridge at 36°N. Site 332 is located in Deep Drill Valley approximately 30 km west of the axis of the Mid-Atlantic Ridge at 36°52'N latitude. The principal goal at this site was deep penetration into layer 2 of the ocean crust by multiple re-entry. Site 334 was drilled on a steep east-facing slope in a small, deep basin near the middle of magnetic anomaly 5. In this area, breccias with gabbro and peridotite clasts in a nannofossil-foram ooze matrix are interlayered with the plutonic rocks and may reflect exposure of a melange in or near the Median Valley of the Mid- Atlantic Ridge prior to burial by later basaltic extrusions.

    Chemical composition of ocean-floor basalts and separated magnetites DSDP Legs 37, 45 and 46 (1979)

    Description: Titanomagnetites separated from 15 different rock samples (including ocean-floor basalts from DSDP Legs 37, 45 and 46) were analyzed together with whole-rock samples by instrumental neutron-activation analysis for Sc, Cr, Co, Zn, Hf, Ta, Th and the REE La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Yb and Lu. In titanomagnetities from ocean-floor basalts and some other rocks, REE are enriched with respect to the whole-rock composition by factors of between 1.5 and 3 for light REE and between 1.0 and 1.9 for heavy REE; that is, REE with larger ionic radii are preferentially incorporated into the magnetite lattice. Three magnetite samples are REE depleted. Their whole-rock samples contain P in appreciable amounts, so apatite, an important REE-accumulating mineral, could have captured REE to some extent. All titanomagnetites show a marked negative Eu anomaly, this is most probably caused by discrimination of Eu(2+) from the magnetite lattice. Co, Zn, Hf and Ta are significantly enriched in magnetites. The distribution behaviour of Sc and Cr is masked chiefly by the crystallization of clinopyroxene and therefore is not easy to estimate. Ulvöspinel contents of about 70% for the titanomagnetites from ocean-floor basalts were estimated from qualitative microprobe analysis. Ulvöspinel contents of all other samples varied in a wide range from 20% to about 90%. No correlation could be observed between this and the REE contents of the magnetites. Ilmenite exsolution lamellae could only be observed in titanomagnetites from a doleritic basalt from Leg 45.

    Description: Times of vein mineral deposition in the ocean crust have been determined both by Rb-Sr isochron ages of vein smectites and by comparison of 87Sr/86Sr ratios of vein calcites with the known variations of seawater 87Sr/86Sr ratio with time. Results from drilling sites 105, 332B and 418A, Atlantic Ocean, which have basement formation ages of 155 m.y., 3.5 m.y., and 110 m.y., respectively, show that vein deposition is essenrially complete within 5-10 m.y. after formation of the basaltic crust. This provids direct evidence that hydrothermal circulation of sea-water through the oceanic crust is an important process for only 5-10 m.y. after crust formation.

    Description: REE abundances in gabbros and peridotites from Site 334 of DSDP Leg 37 show that these rocks are cumulates produced by fractional crystallization of a primitive oceanic tholeiite magma. They may be part of a layered oceanic complex. The REE distributions in the residual liquids left after such a fractionation are similar to those of incompatible element-depleted oceanic tholeiites. The REE data indicate that the basalts which overlie the gabbro-peridotite complex, are not genetically related to plutonic rocks.

    Description: 143Nd/144Nd ratios have been determined on 37 samples of oceanic basalt, with a typical precision of +/- 2-3 * 10**-5 (2 sigma). Ocean island and dredged and cored submarine basalts are included for which reliable measurements of 87Sr/86Sr ratios exist in the literature or have been measured as part of this study. A strong negative correlation exists between 143Nd/144Nd and 87Sr/86Sr ratios in basalts from Iceland and the Reykjanes Ridge, but such a clear correlation does not exist for samples from the Hawaiian Islands. However, when other ocean island basalts from the Atlantic are included there is an overall correlation between these two parameters. Increases and decreases in Rb/Sr in oceanic basalt source regions have in general been accompanied by decreases and increases respectively in Sm/Nd ratios. The compatibility of the data with single-stage models is assessed and it is concluded that enrichment and depletion events, which are consistent with transfer of silicate melts, are responsible for the observed variation.

    Description: Comparison of rates of accumulation of organic carbon in surface marine sediments from the central North Pacific, the continental margins off northwest Africa, northwest and southwest America, the Argentine Basin, and the western Baltic Sea with primary production rates suggests that the fraction of primary produced organic carbon preserved in the sediments is universally related to the bulk sedimentation rate. Accordingly, less than 0.01% of the primary production becomes fossilized in slowly accumulating pelagic sediments [(2 to 6 mm (1000 y)**-1] of the Central Pacific, 0.1 to 2% in moderately rapidly accumulating [2 to 13 cm (1000 y)**-1] hemipelagic sediments off northwest Africa, northwest America (Oregon) and southeast America (Argentina), and 11 to 18% in rapidly accumulating [66 to 140 cm (1000 y)**-1] hemipelagic sediments off southwest America (Peru) and in the Baltic Sea. The emiprical expression: %Org-C = (0.0030*R*S**0.30)/(ps(1-Theta)) implies that the sedimentary organic carbon content (% Org-C) doubles with each 10-fold increase in sedimentation rate (S), assuming that other factors remain constant; i.e., primary production (R), porosity and sediment density (ps). This expression also predicts the sedimentary organic carbon content from the primary production rate, sedimentation rate, dry density of solids, and their porosity; it may be used to estimate paleoproductivity as well. Applying this relationship to a sediment core from the continental rise off northwest Africa (Spanish Sahara) suggests that productivity there during interglacial oxygen isotope stages 1 and 5 was about the same as today but was higher by a factor of 2 to 3 during glacial stages 2, 3, and 6.

    Description: Oceanic crustal drilling by R. V. Glomar Challenger at 15 sites in the North Atlantic has led to a complex picture of the upper half kilometer of the crust. Elements of the picture include the absence of the source for linear magnetic anomalies, marked episodicity of volcanic activity, ubiquitous low temperature alteration and evidence for large scale tectonic disturbance. Comparison sections in the Pacific and much deeper crustal drilling are needed to attack problems arising from the North Atlantic results.

    Description: Refractory megacrysts of olivine, plagioclase, chromian diopside and Cr-Al spinel, which were not in equilibrium with the host oceanic tholeiite on eruption, are present in samples from several dredge sites and DSDP drill sites in the Atlantic and Pacific Oceans. They have multiple origins: (1) cognate or accidental mantle fragments; (2) relict fragments from fractional crystallization of parental liquids considerably more primitive than oceanic tholeiite; and most commonly (3) the fractional crystallization products of such liquids mixed with oceanic tholeiite magma. Melt inclusions in chrome-spinel phenocrysts provide evidence for this postulated Mg- and Ca-rich magma which has counterparts in the Scottish Tertiary Province and in west Greenland.

    Description: Oxygen isotopic and microfaunal analyses and shell size variations of Orbulina universa in two Indian Ocean cores indicate that the position of the Subtropical Convergence has fluctuated between a northern limit north of 31°S during glacial stages and its present, maximum southern limit. The northward displacement of the Subtropical Convergence to a position off Durban, South Africa, reflects the general weakness of the Agulhas Current during glacial stages and parts of interglacial stages, representing about 65 percent of the past 540,000 years.

    Description: Phosphate deposits which apparently formed during the Miocene climatic optimum are widespread on the Chatham Rise and Camp bell Plateau, and on seamounts in the north Tasman Sea. They formed under oxidising conditions by the phosphatisation of older or contemporaneous foraminiferal oozes (Campbell Plateau and Chatham Rise) and coral limestones (Tasman Sea). The phosphorites of the rise and plateau were formed where current activity was sufficiently strong to prevent normal sedimentation, and now form lag deposits. After the Miocene, phosphorite formation ceased and was followed by manganese oxide deposition where conditions were highly oxidising on the eastern Campbell Plateau and north Tasman seamounts, and by glauconite formation in the much less oxidising environments of the western Campbell Plateau and the Chat ham Rise. The manganese deposits are not volcanogenic, as was formerly thought, but formed by slow precipitation from well oxygenated sea water.

    Description: Bulk composition of ferromanganese nodules from the pelagic environment of the Pacific Ocean is apparently related to nodule-growth rate, sediment-accumulation rate, and biologic productivity in the overlying seawater. Nodules with a high Mn/Fe ratio and high Ni and Cu concns tend to occur in areas where primary productivity in the surface layer of the ocean is high and the sediment accumulation rate low. They may have a Mn/Fe ratio as low as one and accrete at rates as low as 1 mm per 1 million years. Nodules with a larger Mn/Fe ratio apparently have growth rates that are greater by as much as a factor of 10.

    Description: The continental slope and rise, east of Newfoundland, accommodates two distinct gravel populations. The upper slope (300-700 m depth) population is characterized by unstained, granules to boulders of predominantly granitic and terrigenous sedimentary compositon that show affinity to Paleozoic and Proterozoic rocks of Newfoundland and areas further north. The rise (2,500-〉3,000 m depth) population consists of iron- and ferromanganese-stained granules to cobbles composed mainly of carbonate that presumably has been derived from the high Canadian Arctic. The rise clasts are further distinguished in that they are finer grained, slightly more rounded and more altered by solution and/or boring organisms than their shallower water counterparts. The upper slope gravel has been reworked from underlying sediments, and deposited from ice rafts, and both processes are probably continuing today. Gravel on the rise has been concentrated through winnowing of middle Holocene sediments by the Western Boundary Undercurrent which appears to have been operative as a winnowing agent since about 4,000 to 5,000 y BP. The undercurrent has also affected the distribution of stained gravel which is most common and most intensely stained beneath a fast-flowing undercurrent core where environmental conditions resemble those documented for deep-sea, ferromanganese nodule fields.

    Occurence of benthic foraminifera off Boknis Eck, western Baltic Sea (Tables 12-24) (1976)

    Description: Samples of algae and sediment were taken between July 1973 and May 1975 at intervals of 2-5 weeks from a number of depths at the entrance of Eckernförder Bay (Western Baltic Seal. The purpose was to ascertain the correlation between the settlement of foraminifera and ecofactors, and to determine the annual carbonate production by foraminifera. Produection data were compared with the foraminifera content of the sediments. Information on the extend and place of dissolution could be gained by measuring the saturation of the water with mineral carbonates. The exact area of colonisation (=sediment surfaee, in the sediment or on algae, Fig. 6) was determined for the most important speeies of the Western Baltie. Reproductions were not regulated by one environmental factor, but rather by a number of these. Here the abiotic parameters appear to play the more important part. The conditions necessary for the start of a reproduction can, however, also be fulfilled by the presence of symbiotic algae or increased food avai1ability (Fig. 6). The growth of the foraminifera lasts 3 to 5 months. Carbonate production by foraminifera amounts to between 0.1 and 0.04 g CaC03/m**2 pa in the residual sediment area and up to 3.12 g CaCO3/m**2 pa in the basins. The species living on algae only produce up to 0.003 g CaCO3/m**2 pa (Tab. 9, Fig. 9). The carbonate production figures are only 1-3 % of those reached by the large foraminifera in tropical latitudes, however, similar values were found in the Adriatic. Only 0-3 % of the carbonate produced by the foraminifera is preserved (Tab. 11). In the residual sediment area all foraminiferal carbonate produced is destroyed or washed out. The highest preservation was found in the deepest basins; here, not only is more produced, but also more is preserved. In the sha1lower part of the area of investigation the tests are destroyed by the continual restratification of the sediment and also through being washed out and transported away. In the deeper areas dissolution and predation are major faetors. For some months of the year the water column is under-saturated with mineral carbonates, while there is over-saturation in the interstitial water below a sediment depth of about 1 cm. Therefore tests must be dissolved on the surface or in the uppermost millimetres of the sediment. The quantity of calcareous foraminifera in the sediments is regulated by the following factors: a) intensity of water movement, b) oxygen content of the bottom water (regulates settlement of macrobenthos and bacterial growth), e) rate of sedimentation, d) grain size composition of the sediment. A far more important part than previously assumed is played by the burrowing macrobenthos. The animals transport some foraminifera tests from the sediment surface, where they are exposed to dissolution, into the deeper parts of the sediment, where they can be preserved. On the other hand high colonisation density of macroorganisms feeding on substrate and foraminifera can, in extreme cases, lead to the total destruction of the tests.

    Description: Mineralogical analysis of manganese nodules and crusts collected from Indian ocean aboard Marion Dufresne points to a depth and regional control upon the manganese oxide association: vernadite - birnessite and vernadite - todorokite. Moreover, progressive changes in the vernadite/birnessite ratio as a function of time is clearly seen. Magnetite and titano-magnetite in quantities similar to those of framboidal pyrite in manganese nodules are outlined for the first time. Study of the distribution of metals (Mn, Fe, Ni, Cu, Co) shows a strong latitudinal and regional dependence that may be connected to high productivity zones and to bottom water properties. The problem of mineralogical control on the chemical composition is approached. Finally, it results that any interpretations taking into account all these data haveway to give to the variability of sea-water properties (pH, oxygenation, motions) the prominent control upon manganese nodules composition.

    Description: The CaCO3-contents and the fractions 〉 40 µm have been analysed from 5 kastenloten, one piston core and two kastengreifer taken between Senegal and Cape Verde Islands. Numerous benthonic and planktonic organisms and different terrigenous components have been distinguished. The four cores off Senegal reach middle Wuerm sediments; cores GIK12329-6 and TAG72-1 reach the V-zone and core GIK12331-4 the X-zone (Eem); the two kastengreifer contain sediments of Holocene age. Correlation of the cores has been made. Holocene sedimentation rates decrease from the shallow cores (6-11 cm/1000 years) to the deep-sea (1-2 cm/1000 years). The following climatic variations could be deduced from the sediments off the Senegal: during Holocene climate was in general as today, the Senegal river transporting fine grained material to the sea. The upper Wuerm was arid with no river influence but with red dune sand transported to the continental slope. During middle Wuerm the climate was humid again. The deep-sea cores have been influenced by eolian material from arid regions during glacial and interglacial periods, indicated by relatively high "Wuestenquarz-numbers". However, during Wuerm "Wuestenquarz-numbers" are higher than during Holocene and Eem, indicating that more intensely red coloured sediment was exposed to wind activity on the continent during this period. Varying amounts of terrigenous material and CaCO3-contents indicate varying wind strengths (lower in Holocene and Eem than during Wuerm). The boundary between humid and arid Wuerm climate was at approximately 20 °N. Influence of upwelling is difficult to establish in the sediments off Senegal, because river influence, while increasing fertility also dilutes the diatoms which are typical for upwelling. High amounts of organic carbon, low plankton/benthos ratios of foraminifers and low plankton foraminifer/radiolarian ratios in Holocene sections might be interpreted as influenced by upwelling. Turbidites occur in cores 72 and 31 and at the Holocene/Pleistocene boundary of core GIK12329-6. Their composition indicates provenance from the continental shelf of the Cape Verde Islands for core 31 and the continental shelf and slope off Senegal for core TAG72-1. Volcanic material, rare in the normal pelagic sediment of core GIK12331-4 is more frequent in the turbidites.

    Description: Two hundred and seventy five mollusc species from the continental shelf off Southern Spanish Sahara (depth: 32-60 m) were identified. Their distribution pattern is strongly influenced by the nature of the bottom (firm substrate, shelter, stability of sediment) rather than other factors at that depth interval. This faunal assemblage shows great affinity to the Mediterranean and Lusitanian faunas, and comprises only few (22 %) exclusively Senegalese and species living south of Senegal.

    Description: Six soft sediment cores, up to and over 9 m in length, and additional surface samples were selected for study of their planktonic foraminifera to provide information on the Holocene and Pleistocene stratigraphy of the West African continental margin south of the present boundary of the Sahara. The material was collected by the German research vessel "Meteor" during Cruise 25 in 1971. The residues larger than 160 microns determined, counted and statistically evaluated. Stratigraphical correlations with trans- Antlantic regions are given by occurrence of Truncorotalidoides hexagonus and Globorotalia tumidula flexuosa which mark the last interglacial stage. According to the climatic record the two deep-sea cores extend down to the V-zone, considered here as equivalent to the Mindel-Riss-interglacial time, as there are three distinctly warm and two cold periods indicated in the cores by planktonic foraminiferal faunas. Z-zone = Holocene is present in all cores, Y-zone = Wuermian glacial can be divided into five section, three cold and two warm stages; the X-zone can be divided into three warm stages, separated into two cool periods. The earliest warm stage is indicated to be the warmest one. There are excellent correlations to the Camp century ice core from Greenland, to the Mediterranean, to the Carribean and to the tropical Atlantic as well as to the Barnados stage. The W-zone was correlated to the Riss-glacial. V-zone is a warm period, the upper limit of which being not sufficiently defined, which contains also some cool sections. Increasing sedimentation rates from the deep-sea to the upper slope reveal climatic and regional details in Holocene and Late Pleistocene history of the continental margin. These were based mainly on different parameters of planktonic foraminiferal thanatocoenoses which are the main components of the size fraction 〉160 microns of the pelagic core. They become incerasingly diluted by other faunal and terrigenous components with decreasing slope depths. Estimates of absolute abundances, ranging from 25000 specimens/gm of sediment in the deep sea to less than 100, indicate various sedimentary processes at the continental margin. An ecological correlation by dominant species is possible. Readily computed temperature indices of different scales are presented which indicate, for instance, three distinctly cold sections within the last glacial and seven warm sections within the last interglacial lime. These are used for estimates of sedimentation rates. During cold periods sedimentation rates are higher than during warmer periods. Stratigraphic correlation and faunal record, combined with absolute abundances and sedimentation rates, indicated that in the deep sea turbidity currents not only cause high sedimentation rates for short periods of time, but also that material is occasionally eroded. Effects of upwelling may be detected in the surfacc sediment samples as well as in late Pleistocene and early Holocene samples of the slope by planktonic foraminiferal data which are not influenced by sedimentary processes.
