Sedimentology of sites 14-141, 41-366, 47-397 and 79-544B
Along the N-S-transect of DSDP-Sites 5446, 397, 141, and 366, oxygen and carbon isotopes, flux rates of calcium carbonate, terrigenous matter, and biogenic opal, clay minerals... -
Composition of organic matter from black shales drilled in the Cape Verde Bas...
Results of geochemical studies of organic matter in black shales from the Cape Verde Basin are reported. Based on these results, in combination with data of petrographic... -
Organic matter from black shales collected in DSDP Holes 41-367 and 41-368
It is shown that microscopic algae dominate in source material of organic matter of black shales, and admixture of residues of organisms and terrestrial humic material is... -
Chemical composition of bottom sediments and rocks from DSDP Holes 3-14 throu...
Data on analyses of chemical composition of DSDP samples of bottom sediments and rocks carried out in P.P. Shirshov Institute of Oceanology are reported. Basal sediments and... -
Organic geochemistry of DSDP Leg 41 holes
The black shale encountered in Cretaceous cores of the Cape Verde area during the DSDP Leg 41 are of marine origin and correspond to excellent potential oil source rocks. They... -
Stable isotopic and carbonate cyclicity in deep sea sediments from different ...
Oxygen and carbon isotopic variability of the dominant (<38 µm) carbonate fraction within bedded, organic-carbon rich Lower Cretaceous sediment intervals from various DSDP... -
Neogene planktonic foraminifera of DSDP Leg 41 holes
During Leg 41 Neogene sediments were recovered from five sites off northwest Africa.On the Sierra Leone Rise (Site 366), Neogene sediments consist of nanno oozes, nanno chalk,... -
Microfossil occurrence in Pliocene-Quaternary sediments of the North Atlantic
Planktonic foraminiferal and nannoplankton stratigraphy of the Pliocene-Quatemary Sediments of the northern half of the Atlantic Ocean from the equator up to the Rockall Plateau... -
Carbon isotopic composition of biomarkers of Cenomanian sediments of DSDP Hol...
The stable carbon isotopic compositions of free and sulfur (S)-bound biomarkers derived from algae, (cyano)bacteria, archaea and higher plants and total organic carbon (TOC)... -
Oligocene to Miocene stable isotope record and planktonic foraminifer biostra...
We have integrated Oligocene to lower upper Miocene planktonic foraminifer biostratigraphy with benthic foraminifer (Cibicidoides spp.) stable isotope records for two sites... -
Cenomanian/Turonian sea surface temperatures of the equatorial Atlantic recon...
Oceanic anoxic event 2 (OAE-2) occurring during the Cenomanian/Turonian (C/T) transition is evident from a globally recognized positive stable carbon isotopic excursion and is... -
Chemical and mineral compositions of sedimentary deposits and magmatic rocks ...
This collective monography by a group of lithologists from the Geological Institute of the USSR Academy of Sciences summarizes materials of the Deep-Sea Drilling Project from... -
Revised chronology of Neogene DSDP holes from the World Ocean
After nearly 30 years of growth in geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated. In this... -
Occurrence of hiatuses PH and NH 1 through NH 7 in DSDP holes
Miocene paleoceanographic evolution exhibits major changes resulting from the opening and closing of passages, the subsequent changes in oceanic circulation, and development of... -
Oxygen and carbon isotopic composition in Eocene and Oligocene planktonic and...
Oxygen and carbon isotope ratios in Eocene and Oligocene planktonic and benthic foraminifera have been investigated from Atlantic, Indian, and Pacific Ocean locations. The major... -
Geochemistry of planktonic foraminifera from DSDP sites in the Atlantic and P...
The lithium content of planktonic foraminiferal calcite has been determined to evaluate temporal variability of seawater Li concentrations over the past 116 m.y. Mean... -
Carbon chemistry of cretaceous marine organic matter
Geochemical studies of Cretaceous strata rich in organic carbon (OC) from Deep Sea Drilling Project (DSDP) sites and several land sections reveal several consistent... -
Nitrogen isotope ratios of Cretaceous Atlantic sedimentary sequences
At two locations in the Atlantic Ocean (DSDP Sites 367 and 530) early to middle Cretaceous organic-carbon-rich beds (black shales) were found to have significantly lower... -
Strontium isotope ratios of pore waters and planktonic foraminifera from DSDP...
A detailed record of the strontium-87 to strontium-86 ratio in seawater during the last 100 million years was determined by measuring this ratio in 137 well-preserved and...
