Geochemistry of tetrapyrrole, carotenoid, and perylene pigments in sediments ...
Twenty-one core samples from DSDP/IPOD Leg 63 were analyzed for products of chlorophyll diagenesis. In addition to the tetrapyrrole pigments, perylene and carotenoid pigments... -
Grain-size distribution, carbon and calcium carbonate at DSDP Leg 63 Holes
Sand-silt-clay distribution was determined at Scripps on samples collected at the time the cores were split and described. The sediment classification used here is that of... -
Organic- and carbonate-carbon values and extract data for DSDP Holes 63-467 a...
Quantity, type, and maturity of the organic matter of middle Miocene to Quaternary sediments from the eastern North Pacific (Deep Sea Drilling Project Leg 63) were determined.... -
Distribution of organic matter and gases in sediments at DSP Leg 63 Holes
As part of our continuing organic geochemical studies of sediments recovered by the Deep Sea Drilling Project, we have analyzed the types, amounts, and thermal alteration... -
Petrographic and chemical characteristics of diabases at DSDP Holes 63-469 an...
Diabasic rocks were recovered at Sites 469 and 471 on IPOD/DSDP Leg 63. The diabasic rocks are composed mainly of Plagioclase, clinopyroxene, and low-temperature alteration... -
Petrographic and chemical characteristics of abyssal tholeiites at DSDP Leg 6...
Tholeiitic basalts were obtained from basaltic basement ranging in age from 6 to 17 m.y. on IPOD/DSDP Leg 63. The main rock types encountered at all sites but 473 are basaltic... -
Chemistry of the massive sulfide deposit at DSDP Hole 63-471
We report here chemical analyses of sulfide and other minerals occurring in the massive sulfide deposit cored at Site 471. Details of the mineralogy and inferred paragenesis of... -
Clay minerals and their assemblages at DSDP Leg 63 Holes
This paper discusses the distribution of clay minerals and identification of their assemblages in relation to sedimentary facies encountered during DSDP Leg 63 drilling off... -
Isotopic survey of diagenetic carbonates, at DSDP Leg 63 Holes
Authigenic carbonates, principally calcium-rich dolomites, with extremely variable isotopic compositions were recovered in organic-rich marine sediments during Leg 63 drilling... -
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... -
C1-C8 hydrocarbons in marine sediments
Light hydrocarbon (C1-C8) profiles are compared for three wells of varying maturities: two immature DSDP wells (Site 397 near the Canary Islands and Site 530A near the Walvis... -
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... -
Composition of sediments and cores from DSDP Legs 54 and 61-63
The monograph gives results of studies of sediments and rocks collected from D/S Glomar Challenger in the Pacific Ocean. These studies have been based on the lithological facial... -
Stable carbon and oxygen isotope ratios of foraminifera from Cretaceous and P...
Detailed analysis of over 200 samples of uppermost Cretaceous and Paleocene sediments from Atlantic Ocean DSDP Sites 384, 86, 95, 152, 144, 20C, 21, 356, 357, and 329 provides... -
Recalculated petrographic parameters and normalized microprobe analyses of vo...
The southward passage of the Rivera triple junction and its effect on the North American plate are primary controls on the Miocene tectonic evolution of the outer borderland of... -
Carbon chemistry of cretaceous marine organic matter
Geochemical studies of Cretaceous strata rich in organic carbon (OC) from Deep Sea Drilling Project (DSDP) sites and several land sections reveal several consistent... -
Petrographic data for samples from DSDP Holes 63-471 and 65-485
Detrital modes of middle Miocene sandstone recovered at Deep Sea Drilling Project Site 471 on the Magdalena Fan support the hypothesis that the fan has been displaced northward... -
Magnetic properties of Cenozoic MORB and Cretaceous MORB from DSDP and ODP holes
The fact that the natural remanent magnetization (NRM) intensity of mid-oceanic-ridge basalt (MORB) samples shows systematic variations as a function of age has long been... -
Organic geochemistry of DSDP Site 467
Results of the analyses of twenty-three samples from the Middle Miocene to Lower Pliocene strata from DSDP Site 467, offshore California, are presented. The analyses were... -
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...
