Coarse-silt-fraction mineralogy at DSDP Legs 56 and 57 Holes
Soviet sedimentologists use the term "coarse silt" to denote the size fraction 0.1 to 0.05 mm (50-100 µm). Petelin (1961) has shown that this fraction is most diagnostic for... -
Bulk composition and clay mineralogy at DSDP Legs 56 and 57
Altogether 513 samples from sediments of Cretaceous to Pleistocene age from DSDP Legs 56 and 57 were examined by x-ray methods. The main constituents are clay minerals, quartz,... -
Calcareous-nannofossil biostratigraphy at DSDP Leg 57 Holes
As a continuation of the Japan Trench transect commenced by DSDP Leg 56, 10 holes were drilled and 273 cores were recovered while occupying Sites 438, 439, 440, and 441 during... -
Mineralogy and geochemistry of volcanic ash at Japan Trench from DSDP Legs 87...
Volcanogenic sediments were obtained from Site 584, located on the midslope of the Japan Trench. Occurrences of volcanic ash in the diatomaceous mudstones increase within... -
Highly dealkylated copper and nickel etioporpyfrins in marine sediments
Copper porphyrins have been recognized as natural constituents of marine sediments only within the past 5 years (Palmer and Baker, 1978, Science201, 49–51). In that report it... -
Paleoelevations in the Pacific Ocean 35 million years ago
Data from deep sea drilling, linear magnetic anomalies and bathymetric measurements together with age and morphometric characteristics of seamounts have been used to construct a... -
Ether-derived alkanes from sedimentary organic matter
Glycerol ether lipids have been detected in the bitumen of DSDP sediments from Sites 467, 440B and 380 and from the Green River Shale. The alkyl side groups of these ethers were... -
Revised chronology of Neogene DSDP holes from the World Ocean
After nearly 30 years of growth in geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated. In this... -
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... -
Occurrence of hiatuses PH and NH 1 through NH 7 in DSDP holes
Miocene paleoceanographic evolution exhibits major changes resulting from the opening and closing of passages, the subsequent changes in oceanic circulation, and development of... -
New calibration of Neogene radiolarian events in the North Pacific
New age models for twelve Deep Sea Drilling Project sites in the North Pacific have been produced, based on (in order of importance in our dataset) a recompilation of previously... -
