Geochemistry at DSDP Leg 75 Holes
Samples of sediments and rocks collected at DSDP Sites 530 and 532 were analyzed for 44 major, minor, and trace elements for the following purposes: (1) to document the downhole... -
Electrical resistivity, formation factors, and sound velocity at DSDP Holes 7...
From 0 to 277 m at Site 530 are found Holocene to Miocene diatom ooze, nannofossil ooze, marl, clay, and debrisflow deposits; from 277 to 467 m are Miocene to Oligocene mud;... -
Geotechnical properties of sediments at DSDP Site 75-532
During Leg 75 of the Deep Sea Drilling Project (DSDP) from the D/V Glomar Challenger, a 200-m deep hole was drilled at Hole 532A on the eastern side of Walvis Ridge at a water... -
Major and trace elements of basalts and basaltic pebbles at DSDP Hole 75-530A
Deep Sea Drilling Project Leg 75 drilled into igneous basement in the Angola Basin at Site 530, located about 20 km north of the escarpment at the eastern end of the Walvis... -
General descriptions, organic contents and ratios of geolipid components at D...
Distributions of free and bound n-alkanes, n-alkanoic acids, and n-alkanols were determined in order to compare the character of organic matter contained in organic-carbon-rich... -
Lithology, stratigraphy, organic carbon content, extract and liquid chromatog...
Seventeen sediment samples of Albian-Cenomanian to early Pliocene age from DSDP Hole 530A in the Angola Basin and six sediment samples of early Pliocene to late Pleistocene age... -
Low-molecular-weight hydrocarbon concentrations, organic carbon contents, and...
A series of C2-C8 hydrocarbons (including saturated, aromatic, and olefinic compounds) from deep-frozen core samples taken during DSDP Leg 75 (Holes 530A and 532) were analyzed... -
Organic facies variations in the Mesozoic South Atlantic DSDP Holes
Visual kerogen and total organic carbon determinations indicate that there are two periods of organic enrichment events in the Mesozoic sediments of the South Atlantic. The... -
Organic geochemical character of selected cores at DSDP Hole 75-530A
The Albian/Cenomanian strata in Hole 530A are organically richer than are the post-Cenomanian strata. Organic matter is thermally immature and appears to be of dominantly marine... -
Organic geochemical comparison of Cretaceous green and black claystones at DS...
Three pairs of Upper Cretaceous black shales and adjacent green claystones from Hole 530A were analyzed to compare types and amounts of organic matter and lipids and to seek... -
Migration of C1 to C8 volatile organic compounds in sediments at DSDP Hole 75...
The distribution of C1 to C8 hydrocarbons in sediment samples from DSDP Leg 75, Hole 530A, indicates that significant amounts of methane and ethane have migrated from... -
Organic geochemistry of Cretaceous black shales at DSDP Hole 75-530A
Five-hundred ten meters of Cretaceous sediments were drilled north of the Walvis escarpment in Hole 530A during Leg 75. An immature stage of evolution for organic matter can be... -
Geochemistry of organic carbon at DSDP Sites 75-530 and 75-532
CHN analyses of sediments and rocks sampled during DSDP Leg 75 in the South Atlantic have provided concentrations of organic carbon and atomic C/N ratios of organic matter from... -
CaCO3, organic carbon and mass accumulation rates at DSDP Site 75-532
Detailed carbonate and organic-carbon stratigraphies were constructed from samples collected every 20 cm in a 250-m hydraulic piston core recovered at DSDP Site 532 on Walvis... -
Occurrence of Inoceramus in the South Atlantic and oxygen isotopic paleotempe...
Inoceramus occurs in every DSDP hole that penetrated Cretaceous sediments in the South Atlantic Ocean, and specimen occurrence has been mapped in detail for each core. Oxygen...
