(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) Counts and ratios of microfossils at DSDP Hole 64-480
We examined the relative abundance of various components in the coarse fraction (> 150 µm) from a selected portion of the DSDP Site 480 piston core. The components consist... -

Analysis of individual laminae in Recent sediments from the slopes of the Guaymas Basin indicates an increased abundance of the larger sizes (>60 µm) of Coscinodiscus... -
(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) 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) 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... -

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... -
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... -
