(Table 1) Oxygen and carbon isotopic values of benthic foraminifera from the ...
Stable isotopic data from benthic foraminifera indicate the occurrence of at least three deepwater masses in the late Maastrichtian ocean. Given mean oceanic d18Ow of -1.0 per... -
(Table 1) Helium concentration in sediments
Two decades ago, Merrihue (1964) reported 3He/4He ratios of >10-4 in ferromagnetic separates from a Pacific deep ocean red clay and concluded that the high ratio is due to... -
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... -
Chert intervals in DSDP and ODP sites (Table 1)
Radiolarian cherts in the Tethyan realm of Jurassic age were recently interpreted as resulting from high biosiliceous productivity along upwelling zones in subequatorial... -
Benthic foraminiferal number of specimens in Cretaceous samples of various DS...
Benthic foraminifera from 24 DSDP/ODP sites were investigated to assess their global horizontal and vertical distribution in the deep-sea environment at the end of the... -
Nitrogen isotopes of bulk sediments for OAE2 samples
Sediment records of the stable isotopic composition of N (d15N) show light d15N values at several sites in the proto-North Atlantic during Oceanic Anoxic Event 2 (OAE 2) at the... -
Mineral and chemical compositions of sedimentary and volcano-sedimentary rock...
Sedimentary cover on the bottom of the Northwest Atlantic Ocean is underlain by Late Jurassic - Cretaceous tholeiite-basalt formation. It consists of come sedimentary formations... -
Stable carbon and oxygen isotope record of benthic foraminifera from Paleocen...
A major change in Cenozoic deep-sea benthic foraminifera occurred in the Atlantic, Indian, and Pacific oceans near the Paleocene/Eocene boundary. Benthic foraminiferal abundance... -
Strontium isotope ratios of planktonic foraminifera from sediment samples acr...
Seawater 87Sr/86Sr values increase abruptly by 28 * 10**-6 across the Cretaceous/Tertiary boundary (KTB). This small, but rapid shift is superimposed on the larger scale... -
Total number of benthic foraminifera in sediments below the K/T boundary in t...
Most species of Late Cretaceous deep-sea benthic foraminifera are believed to be cosmopolitan and therefore to exhibit only minor biogeographical differences. In this... -
Contusotruncana contusa abundances and morphotypes in the cretaceous mid-lati...
Spatial and temporal patterns in test size and shape (test conicity and spiral roundness) and absolute abundance (accumulation rate) of the planktonic foraminifer... -
Chemical composition of DSDP and ODP cherts
Rare earth element (REE), major, and trace element abundances and relative fractionations in forty nodular cherts sampled by the Deep Sea Drilling Project (DSDP) and Ocean... -
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... -
Diversity of abyssal agglutinated foraminifera from Cenomanian to Santonian s...
Benthic foraminiferal assemblages of distinctive taxonomic composition occur at the top of benthic fossil-free black shales which correspond to the anoxic event at the... -
Latitudinal variation in the planktic foraminifer Contusotruncana contusa in ...
The morphological variability (coiling properties, size and shape) of the planktic foraminifer Contusortuncana contusa (Cushman) in the terminal Cretaceous ocean was examined at... -
Benthic foraminifera in Lower Cretaceous sediments from various DSDP samples
From the DSDP Legs 1, 11, 13, 17, 25, 27, 32, 36, 41, 43, 44, 50, and 62 the Lower Cretaceous foraminifers have been investigated for biostratigraphical, taxonomical, and... -
Highly dealkylated copper and nickel etioporpyfrins in marine sediments
Copper porphyrins have been recognized as natural constituents of marine sediments only within the past 5 years (Palmer and Baker, 1978, Science201, 49–51). In that report it...
