Mineralogy and petrographic summary of ODP Leg 198 sites and DSDP Hole 62-463...
This petrological study of the lower Aptian Oceanic Anoxic Event (OAE1a) focused on the nature of the organic-rich interval as well as the tuffaceous units above and below it.... -
Benthic foraminifera across the Cretaceous/Paleogene boundary in ODP Hole 198...
Deep-sea benthic foraminifera show important but transient assemblage changes at the Cretaceous/Paleogene (K/Pg) boundary, when many biota suffered severe extinction. We... -
Mineralogy and stable oxygen isotope ratios of the Cretaceous-Tertiary boundary
Results of detailed mineralogical, chemical, and oxygen isotope analyses of the clay minerals and zeolites from two Cretaceous-Tertiary (K/T) boundary regions, Stevns Klint,... -
Morphometry of calcareous nannofossils from the Oceanic Anoxic Event 1a
Ocean acidification induced by atmospheric CO2 may be a major threat to marine ecosystems, particularly to calcareous nannoplankton. We show that, during the Aptian (~120... -
Geochemistry of sediments from the Cretaceous-Tertiary boundary
Siderophilic element concentrations are high in sediments from the Cretaceous-Tertiary boundary. An extraterrestrial source is indicated. Concentrations are too high to be... -
Physical properties and neutron texture measuerments of deep-sea carbonates o...
In weakly indurated, nannofossil-rich, deep-sea carbonates compressional wave velocity is up to twice as fast parallel to bedding than normal to it. It has been suggested that... -
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 matter composition of Cretaceous sediments of the central Pacific Ocean
Complete records of organic-carbon-rich Cretaceous strata were continuouslycored on the flanks of the Mid-Pacific Mountains and southern Hess Rise in the central North Pacific... -
Composition of sediments and cores from DSDP Legs 54 and 61-63
The monograph gives results of studies of sediments and rocks collected from D/S Glomar Challenger in the Pacific Ocean. These studies have been based on the lithological facial... -
Composition of post-Jurassic deposits from the Northwest Pacific and the Gala...
The monogragh contains results of mineralogicai and geochemical studies of Mesozoic and Cenozoic deposits from the Pacific Ocean collected during Deep Sea Drilling Project.... -
Strontium isotope ratios of DSDP samples
The isotopic ratio of strontium-87 to strontium-86 shows no detectable variation in present-day ocean water but changes slowly over millions of years. The strontium contained in... -
Chemical, isotopic and isotope-chronological data for samples from DSDP Hole ...
Basalt sills cored in lowermost Berriasian sediments on Shatsky Rise in the northwest Pacific yield a mean 40Ar-39Ar incremental heating age of 144.6+/-0.8 Ma, providing a... -
Distribution of abundance of planktic foraminifera and calcareous nannofossil...
New paleomagnetic and paleontologic data from Pacific DSDP Sites 463 and 167 define the magnetic reversals that predate the Cretaceous Normal Polarity Superchron (K-N). Data... -
Foraminiferal oxygen and carbon isotope data for DSDP Sites 32-305 and 62-463...
Oxygen isotope analyses of well-preserved foraminifera from Blake Nose (30°N paleolatitude, North Atlantic) and globally distributed deep-sea sites provide a long-term... -
Strontium isotope data from DSDP Sites 32-305 and 62-463 and ODP Sites 113-68...
Fluctuations in oxygen (d18O) and carbon (d13C) isotope values of benthic foraminiferal calcite from the tropical Pacific and Southern Oceans indicate rapid reversals in the... -
Stable oxygen and carbon isotope ratios and paleotemperature reconstructions ...
Inoceramus is an epibenthic bivalve which lived in a wide variety of paleoenvironments encompassing a broad range of paleodepths. A survey of all Cretaceous sediments from Deep... -
Chemical composition of DSDP cherts and associated host sediments
Chert and associated host sediments from Monterey Formation and Deep Sea Drilling Project (DSDP) sequences were analyzed in order to assess chemical behavior during diagenesis... -
