Geochemistry and strontium isotopic composition of interstitial waters of mar...
The concentrations and isotopic compositions of strontium in interstitial waters from several DSDP sites, where sediments consist chiefly of carbonate oozes and chalks, are used... -
Age models and stable isotope ratios from the Mid-Miocene
Mid-Miocene pelagic sedimentary sections can be correlated using intermediate and high resolution oxygen and carbon isotopic records of benthic foraminifera. Precision of a few... -
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geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated.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... -
Sr/Ca ratios of Cenozoic benthic foraminifera
A Cenozoic multi-species record of benthic foraminiferal calcite Sr/Ca has been produced and is corrected for interspecific offsets (typically less than 0.3 mmol/mol) and for... -
Neodymium isotope record of late Paleocene to eraly Eocene fish teeth
High-resolution, fish tooth Nd isotopic records for eight Deep Sea Drilling Project and Ocean Drilling Program sites were used to reconstruct the nature of late Paleocene-early... -
Stable isotope composition of early Danian sediments from the Atlantic Ocean
A long-standing question in Paleogene climate concerns the frequency and mechanism of transient greenhouse gas-driven climate shifts (hyperthermals). The discovery of the... -
Geochemistry of Walvis Ridge basalts
The proposed origins for the Enriched Mantle I component are many and various and some require an arbitrary addition of an exotic component, be it pure sediment or an enriched... -
Geochemistry of the oceanic crust from ocean drilling samples
This book presents new data on chemical and mineral compositions and on density of altered and fresh igneous rocks from key DSDP and ODP holes drilled on the following main... -
Major and trace elements at DSDP Leg 74 Holes
Deep Sea Drilling Project Leg 74 drilled basement on the Walvis Ridge at Sites 525, 527, and 528. These sites are located on the crest and flanks of the segment of the Ridge... -
Major and trace elements and Nd and Sr isotope geochemistry of basalts at DSD...
Basement intersected in Holes 525A, 528, and 527 on the Walvis Ridge consists of submarine basalt flows and pillows with minor intercalated sediments. These holes are situated... -
Interstitial water chemistry at DSDP Leg 74 Holes
Interstitial water studies from sites drilled during a transect of the Walvis Ridge indicate that concentration increases in calcium and decreases in magnesium toward and into... -
Geochemistry at DSDP Leg 74 Holes
Clay mineralogical and inorganic geochemical data from the Campanian to the Pleistocene provide information bearing on the evolution of both continental and marine... -
Age models, accumulation rates, sand and carbonates at DSDP Leg 74 holes
Accumulation rates for the five sites drilled during Leg 74 of the Glomar Challenger are presented on a common timescale based on calibration of datum levels to paleomagnetic... -
Oxygen and carbon isotopes from benthic and planktonic foraminifers at DSDP L...
Oxygen and carbon isotope measurements have been made in picked planktonic and benthonic foraminifers from the five sites drilled on Leg 74, covering the whole Cenozoic. For the... -
Benthic foraminifera and stable isotope composition in Paleocene-Eocene sedim...
In the late Paleocene to early Eocene, deep sea benthic foraminifera suffered their only global extinction of the last 75 million years and diversity decreased worldwide by... -
Organic geochemistry from different DSDP Holes in the subtropical South Atlan...
Organic matter has been characterized in samples of Pleistocene, Pliocene, and Miocene sediments from seven Deep Sea Drilling Project sites in the subtropical South Atlantic... -
Mg/Ca and stable isotope record of benthic foraminifera of the Paleocene-Eoce...
A rapid increase in greenhouse gas levels is thought to have fueled global warming at the Paleocene-Eocene Thermal Maximum (PETM). Foraminiferal magnesium/calcium ratios... -
Sequential variation of carbonate cycles in South Atlantic DSDP locations
We report well-dated Late Cretaceous and Early Tertiary precessional climatic cycles, recorded by rhythmic carbonate maxima and minima in South Atlantic deep sea sites. Spectral... -
Geochemistry of rare earth elements in basalts from Walvis Ridge
Selected basalts from a suite of dredged and drilled samples (IPOD sites 525, 527, 528 and 530) from the Walvis Ridge have been analysed to determine their rare earth element... -
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...
