(Table 1) Minerals found in vesicles and fractures from DSDP Leg 54 Holes bas...
A variety of secondary minerals, formed in response to different oxidation and hydration states, are found in vugs and on fracture surfaces of the basalt cores from DSDP Leg 54.... -
(Table 1) Stable-isotopes of mineral separates and whole-rock powders from al...
Hess Rise, in the western Pacific Ocean, formed in the mid-Cretaceous south of the equator and moved north with the Pacific Plate (Lancelot and Larson, 1975; Lancelot, 1978;... -
(Table 1) K-Ar age and inert-gas-isotopes at DSDP Holes 68-501, 69-504B and 6...
Conventional K-Ar ages have been determined and inert-gas abundances have been measured on representative samples of altered rocks from Deep Sea Drilling Project Holes 501,... -
(Table 1) Sulfur isotopes, total sulfur, and degree of oxidation of basalt sa...
Whole-rock basalt samples from the upper half of Deep Sea Drilling Project Hole 504B have oxygen-isotope compositions typical of mid-ocean-ridge basalts which have experienced a... -
(Table 1) Sulfur isotopes, total sulfur, and degree of oxidation of basalt sa...
About 150 basalt samples from Hole 504B, near the Costa Rica Rift were analyzed for sulfur content and sulfur-isotope composition. The basement in Hole 504B can be divided into... -
(Table 2) Geochemistry of K-feldspars and associated plagioclase phenocrysts ...
Basalts from some holes of the Deep Sea Drilling Project contain secondary K-feldspar which forms pseudomorphs after calcic (>76% An) Plagioclase cores, whereas Plagioclase... -
(Table 1) Apparent ages from 40Ar/39Ar heating steps for DSDP Hole 72-516F ba...
Submarine basalts are difficult to date accurately by the potassium-argon method. Dalrymple and Moore (1968) and Dymond (1970), for example, showed that, when the conventional... -
(Table 1) K, Rb, Cs, Sr, and 87Sr/86Sr in vein materials from DSDP Hole 72-516F
A well-constrained Rb/Sr isochron of secondary celadonites and carbonate from DSDP Hole 516F yields an age of 70.1 ± 1.6 Ma. This age is younger than the age of crust formation... -
(Table 1) Major and trace elements of basalts at DSDP Hole 72-516F
The geochemistry of basalts recovered during Leg 72 is described with emphasis on trace elements. Only Hole 516F penetrated basement; the basalts recovered are... -
(Table 1) Interpillow limestone locations at DSDP Hole 82-562
Interpillow limestones were recovered from numerous cores of Leg 82. Limestones from Core 562-1, south of the Hayes Fracture Zone, display small-scale cross laminations composed... -
(Table 2) Geochemistry and petrograhy of DSDP Leg 82 Holes and MAPCO cruise o...
The compositions of abyssal glasses obtained on Leg 82 of the awGlomar Challenger and the MAPCO cruise of Jean Charcot have been investigated. Two main compositional groups of... -
(Table 1) Oxygen isotopes in minerals at DSDP Hole 83-504B basalts
The D/H, 18O/16O and 87Sr/86Sr ratios of the basaltic basement from the Leg 83 section of DSDP Hole 504B show that in that area the oceanic crust has experienced intensive but... -
(Table 1) Magnetic properties of sediments at DSDP Holes 92-597B and 92-597C
Measurements of magnetic properties were made on basalt samples recovered from Holes 597B and 597C. This paper describes the intensity and inclination of natural remanent...
