Geochemistry and pyrolysis at DSDP Hole 77-535
There are substantial differences in the character of organic matter contained in the Pleistocene and Cretaceous sedimentary sequences of DSDP Site 535. The argillaceous... -
Porosity, permeability, trace elements, and carbon-oxygen isotopes at DSDP Ho...
Talus deposits recovered from Site 536 show evidence of aragonite dissolution, secondary porosity development, and calcite cementation. Although freshwater diagenesis could... -
Investigations of Cretaceous and Tertiary kerogens in sediments of ODP Leg 11...
Seventy-one samples from nine sites were analyzed for total organic carbon (TOC). Fifty-six samples, containing 0.2% or more TOC, were evaluated by Rock-Eval to assess the... -
Abundance of planktic foraminiferal species in sediments at DSDP Sites 10-95,...
Over most of the Gulf of Mexico and Caribbean a hiatus is present between the lower upper Maastrichtian and lowermost Tertiary deposits; sedimentation resumed ~200 ka (upper... -
Iridium contents and microprobe analyses of DSDP Leg 77 samples
Restudy of Deep Sea Drilling Project Sites 536 and 540 in the southeast Gulf of Mexico gives evidence for a giant wave at Cretaceous-Tertiary boundary time. Five units are... -
Planktonic foraminifera of Oligocene sediments from DSDP Hole 77-538A in the ...
A relatively extended Oligocene pelagic sequence with good to medium recovery, drilled during DSDP Leg 77 in the Gulf of Mexico, yielded rich and well diversified planktonic...
