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,... -
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... -
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... -
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... -
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... -
Foraminifera and microfossil occurence in Late Jurassic sediments of the Nort...
Biostratigraphical, taxonomical, and palaeocological results were obtained from Oxfordian to Tithonian foraminifers of the Northern and Southern Atlantic Ocean boreholes of the... -
Dinoflagellate cysts of the Early Cretaceous North Atlantic Ocean
Early Cretaceous dinoflagellate cysts were reinvestigated from nine deep-sea sites of the North and Central Atlantic. In general the zonation scheme developed for the western... -

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... -
Organic carbon and total sulfur content and concentrations of selected molecu...
During mid-Cretaceous times large amounts of organic carbon (Corg) became sequestered in 'black shales', possibly due to 'oceanic anoxic events' characterized by the development... -
Mg/Ca and Sr/Ca in calcites and estimated distribution coefficients in marine...
Recrystallization processes in marine sediments can alter the extent to which biogenic calcite composition serves as a proxy of oceanic chemical and isotopic history. Models of... -
Correlation of Late Jurassic and Early Cretaceous zonation events in ODP and ...
A database was built of 378 stratigraphic events, including first and last stratigraphic occurrences (FO/LO) of calcareous nannofossils, foraminifers, and dinocysts, and... -
