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... -
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... -
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... -
Calcareous nannoplankton of DSDP Leg 43 holes
During Leg 43, six holes (Sites 382-387) were drilled in the western part of the North Atlantic Ocean; locations of sites are shown in Figure 1. Lower Cretaceous to Quaternary... -
Stable carbon and oxygen isotope ratios of foraminifera from Cretaceous and P...
Detailed analysis of over 200 samples of uppermost Cretaceous and Paleocene sediments from Atlantic Ocean DSDP Sites 384, 86, 95, 152, 144, 20C, 21, 356, 357, and 329 provides... -
Geochemistry of the oldest Atlantic oceanic crust
Controversy has surrounded the issue of whether mantle plume activity was responsible for Pangaean continental rifting and massive flood volcanism (resulting in the Central... -
Chemical composition and dated ages of detrital smectites in sediments at DSD...
Mineralogical, morphological and isotopic (Rb-Sr and K-Ar) determinations were made on some detrital smectites of Palaeocene and Cenomanian ages from DSDP. drillings in the... -
Age and chemical composition of apatites from five DSDP and ODP Sites in the ...
Since studies on deep-sea cores were carried out in the early 1990s it has been known that ambient temperature may have a marked affect on apatite fission track annealing. Due... -
Paleocene radiolarian distribution and biostratigraphy from offshore eastern ...
A 100-m-thick Paleocene sequence of mainly pelagic sediments at ODP Site 1121, on the eastern flanks of the Campbell Plateau, contains few to common radiolarians of relatively... -
