Thickness and duration of biostratigraphic zones, assemblages, ages and sedim...
In this Initial Report of the Deep Sea Drilling Project, detailed studies of Sites 533 (gas hydrates) on the Blake Outer Ridge and 534 (oldest ocean history) in the Blake-Bahama... -
Jurassic sedimentation history at DSDP Hole 76-534A
Site 534 reflects a complex interplay of global, basinal, and local influences on sedimentation during the Callovian and Late Jurassic. Rifting and rapid subsidence of the... -
Sedimentology and origin of lower Cretaceous pelagic carbonates and redeposit...
Drilling at Site 534 in the Blake-Bahama Basin recovered 268 m of Lower Cretaceous, Berriasian to Hauterivian, pelagic carbonates, together with volumetrically minor... -
Geochemistry at DSDP Hole 76-534A
At Site 534 in the Blake-Bahama Basin, western North Atlantic, an interval of 68 m of Maestrichtian (Upper Cretaceous) and upper middle to upper Eocene sediments consists of... -
Geochemistry and minerals at DSDP Hole 76-534A
Leg 76 sampled 31.5 m of basaltic basement at Deep Sea Drilling Project Hole 534A in the Blake-Bahama Basin. The basalts represent a short section of mineralogically uniform,... -
Susceptibility and time-dependent magnetization of basalts at DSDP Hole 76-534A
Basalts from Hole 534A are among the oldest recovered from the ocean bottom, dating from the opening of the Atlantic 155 Ma. Upon exposure to a 1-Oe field for one week, these... -
Calcareous nannofossil zonation, ages and sedimentation rates at DSDP Hole 76...
A zonation is presented for the oceanic late Middle Jurassic to Late Jurassic of the Atlantic Ocean. The oldest zone, the Stephenolithion bigotii Zone (subdivided into a... -
Carbonate, organic carbon, pyrolysis and composition of the extracts at DSDP ...
The geochemical studies of Sites 534 and 391 and their comparison allow us to improve the chemical characterization of different geological formations dating from the early... -
Lithology and organic geochemistry at DSDP Hole 76-534
The organic facies of Early and middle Cretaceous sediments drilled at DSDP Site 534 is dominated by terrestrially derived plant remains and charcoal. Marine organic matter is... -
Organic geochemical characteristics at DSDP Holes 76-534A and 44-391C
Pyrolysis assay, bitumen analysis, and elemental analysis of kerogen were used to characterize the organic matter of selected core samples from Hole 534A (Leg 76) and Hole 391C... -
Geochemistry and mineralogy of selected carbonaceous claystones at DSDP Hole ...
Four dominant depositions of carbonaceous claystones are recognized to have occurred during the early Aptian to middle Albian at Site 534. There are correlations of stable... -
Geochemistry at DSDP Site 76-533
Bulk X-ray mineralogy of 47 hemipelagic mud and clay samples from the Blake Outer Ridge has revealed that the sediments contain low magnesian calcite, calcian dolomite, ferroan... -
Geochemistry and isotopes at DSDP Site 76-533
Concentrations and d34S and d13C values were determined on SO4, HCO3, CO2, and CH4 in interstitial water and gas samples from the uppermost 400 m of sediment on the Blake Outer... -
Molecular and isotopic compositions of hydrocarbons at DSDP Site 76-533
In an investigation of gas hydrates in deep ocean sediments, gas samples from Deep Sea Drilling Project Site 533 on the Blake Outer Ridge in the northwest Atlantic were obtained... -
Pressure core barrel characteristics and composition of gases at DSDP Site 76...
A pressure core barrel (PCB), developed by the Deep Sea Drilling Project, was used successfully to recover, at in situ pressure, sediments of the Blake Outer Ridge, offshore the... -
Hydrocarbon gases in Tertiary and Quaternary sediments offshore Peru
Hydrocarbon gases (methane, ethane, propane, isobutane, n-butane, ethene, and propene) are present in Tertiary and Quaternary shelf, upper-slope, and lower-slope deposits of the... -
Palynofacies investigation of Callovian sediments of DSDP Hole 79-534A
During the extension of Deep Sea Drilling Project (DSDP) Leg 76 a new and previously unpenetrated lithological unit composed mainly of claystones was cored above basalt basement... -
Cenozoic radiolarians from the Bahamas
Radiolarians from two sites north of Little Bahama Bank (Sites 627 and 628) are correlated with assemblages from sites on the southeastern U.S. coastal plain and continental...
