Elemental composition and petroleum-generating potential of the methylene chl...
Organic geochemical studies on samples from Holes 487, 488, and 490 in the southern Mexico Middle America Trench provided an opportunity to characterize the organic fraction of... -
Distribution, origin, and hydrocarbon-potential of organic matter in sediment...
As part of an ongoing program of organic geochemical studies of sediments recovered by the Deep Sea Drilling Project, we have analyzed the types, amounts, and thermal alteration... -
Geotechnical properties at DSDP Leg 66 Holes
Delineating the interrelationships between tectonics, sedimentation, and geotechnical properties is particularly important for areas subjected to the dynamic affects of... -
Petrography, minerals and isotopic composition at DSDP Leg 66 Holes
We collected 20 carbonate nodules from the inner trench slope deposits of the Middle America Trench area off Mexico. Carbonate nodules are found only within the methane-rich... -
Petrology at DSDP Leg 66 Holes
The sandstone petrology of Leg 66 samples provides insights into changes through time in the geology of the source regions along the Guerrero portion of the Middle America... -
Chemical composition, characteristics and age of glauconites at DSDP Leg 66 H...
During the analysis of "glaucony" recovered during Leg 66, off Mexico, we reviewed the data on previously studied glaucony layers in active margin areas.We found the depth of... -
Major element compositions, minerals and trace elements at DSDP Leg 67 Holes
Mineralogical (microprobe) and geochemical (X-ray fluorescence, neutron activation analyses) data are given for 18 samples of volcanic rocks from the Guatemala Trench area (Deep... -
Noble gas concentrations of oceanic crust and sediments from the Ninety East ...
We have determined the concentrations and isotopic composition of noble gases in old oceanic crust and oceanic sediments and the isotopic composition of noble gases in... -
Petrological parameters of sands and sandstones from DSDP and ODP holes in ar...
Detrital modes for 524 deep-marine sand and sandstone samples recovered on circum-Pacific, Caribbean, and Mediterranean legs of the Deep Sea Drilling Project and the Ocean...
