(Table 1) Mineral composition at DSDP Leg 64 Holes
Mineral composition and compounds of sediments from the Guaymas Basin. Supplement to: Aguayo, J Eduardo (1982): Appendix III. Composition and source of detrital sand layers from... -
(Table 1) Carbon and nitrogen analyses of samples from DSDP Leg 64 Holes
We analyzed Leg 64 sediments for total carbon and acid-insoluble (organic) carbon using a LECO WR-12 Analyzer. We first dried the 3-5 cm**3 sediment samples at 105°-110°C (some... -
(Table 1) Bulk and clay mineralogy at DSDP Leg 64 Holes
During Leg 64, eight sites were drilled on a transect from young ocean crust to continental crust off Baja California, in the central part of the Gulf of California, where high... -

During the cleaning of the HPC core surfaces from Hole 480 for photography, the material removed was conserved carefully in approximately 10 cm intervals (by K. Kelts); this... -
(Table 1) Minerals of bulk sediment at DSDP Holes 64-480 and 64-481
This paper provides a brief, descriptive, sedimentological background for the chapters on hydraulic piston core Site 480 in this symposium, and supplements data given in the... -
(Table 1) Sulfur isotopes and sulfur content at DSDP Leg 64 Holes
Hydrothermal pyrite samples from Holes 477, 477A, and 478 have sulfur isotope values ranging from about 10 to 11 per mil. Samples with negative sulfur isotope values generally... -
(Table 1) Sample descriptions and geochemistry for core material at DSDP Hole...
Laminated and nonlaminated sediments from Holes 480 and 479 have been analyzed for potential differences in the composition of organic matter. Their lipid composition is very... -
(Table 1) Kerogen geochemistry at DSDP Leg 64 Holes
Twenty-seven kerogen samples from the Guaymas Basin were examined to determine the effects of dolerite sill intrusions on recently deposited organic matter. ESR spin density and... -
(Table 1) Sample descriptions and results: Carbon, lipid, and kerogen analyse...
Pleistocene sediments in the Guaymas Basin, Gulf of California, have been intruded by sills and their organic matter thus subjected to thermal stress. Sediment samples from... -
(Table 1) Carbohydrates, free sugars, and acid-extractable sugar at DSDP Leg ...
We analyzed 10 core samples of Pleistocene and Pliocene sediment for residual carbohydrates. All yielded positive results for total carbohydrates and acid-extractable glucose.... -
(Table 1) Lipid and kerogen content at DSDP Leg 64 Holes
Diatomaceous mud and an organically-rich claystone from holes at Sites 474 and 476 at the mouth of the Gulf of California were analyzed by organic geochemical methods to... -
(Table 1) Organic- and carbonate-carbon and extract for DSDP Leg 64 Holes
We determined the quantity, type, and maturity of organic matter in Pleistocene sediment from the Gulf of California. We analyzed extractable hydrocarbons by capillary column... -
(Table 1) Isotopes on interstitial gases at DSDP Leg 64 Holes
The origin of the interstitial gases of Hole 479 is bacterial. This is indicated by a positive correlation of the 13C concentration in interstitial methane and CO2 in the... -
(Table 1) Sound velocity, wet-bulk density, and acoustic impedance of some in...
The Pliocene-Quaternary sediments that we drilled at eight sites in the Gulf of California consist of silty clays to clayey silts, diatomaceous oozes, and mixtures of both... -
Total organic carbon, lithology and alkylthiophenes in immature sediments (Ta...
A series of novel long-chain 3,4-dialkylthiophenes (C36–C54) was identified in a number of sediments ranging from Pleistocene to Cretaceous. The identifications were based on... -
TOC, carbonate and bitumen concentrations of DSDP Holes 64-477 and 64-478 (Ta...
The bitumens of a selection of subsurface sediments from Guaymas Basin, Gulf of California, have been analyzed in order to assess the hydrothermal effects on the organic matter... -
10Be and 9Be concentrations and ratios of hydroxylamine leachable and residua...
Profiles of both10Be and9Be concentrations have been measured in sediments from the DSDP, Leg 64, Site 477 core. Established in the deep Guaymas Basin, in an area of high heat... -

Interstitial gases from the Deep-Sea Drilling Project (DSDP-IPOD) Leg-64 Sites 474, 477-479 and 481 in the Gulf of California have been analyzed by gas chromatography and... -
(Table 1) The oxygen isotope composition of Site DSDP 480 diatoms
The oxygen isotope composition of marine diatoms from hydraulic piston-cored samples of DSDP Site 480 vary widely, reflecting the great temperature variations and large isotopic...
