Petrographic and geochemical analyses of basaltic rocks dredged from the first segment of the Southwest Indian Ridge near the Rodriguez Triple Junction have been completed in... -
(Table 2) Geochemistry of glasses at DSDP Leg 54 Holes
The compositions of 45 natural basalt glasses from nine dredge stations and six Deep Sea Drilling Project Leg 54 sites near 9°N on the East Pacific Rise have been determined by... -
(Table 1) Geochemistry of sector-zoned crystal at DSDP Hole 45-395A
Variations in crystal morphologies in pillow basalts and probable sheet flows sampled from the region of the East Pacific Rise drilled during Leg 54 are related both to... -
(Table 1) Bulk geochemistry of some lavas at DSDP Hole 55-433C
According to Wilson's (1963a, b) hypothesis, the volcanoes of the Hawaiian-Emperor Chain are formed as the Pacific lithospheric plate moves over a source of magma in the mantle.... -
(Table 1) Chemistry of two samples of the red weathered layer at DSDP Hole 55...
One argument for the subaerial formation of Nintoku Seamount in the Emperor chain is the occurrence of a red claystone interlayered between two basalt flows in Hole 432A.... -
(Table 1) Geochemistry of ash layers at DSDP Leg 57 Holes
The study of the main characteristics of ash layers in Leg 57 cores shows that they are suitable for an analysis of the effect on eruptive activity of their distribution. We... -
(Table 1) Geochemistry of feldspars at DSDP Holes 62-464 and 62-465A
Labradorite is the principal feldspar in tholeiitic basalt from Deep Sea Drilling Project Site 464, on northern Hess Rise. Andesine and oligoclase constitute most primary... -
(Table 2) Geochemistry at DSDP Holes 62-464 and 62-465A
Igneous rocks were recovered from three sites on Hess Rise during Deep Sea Drilling Project Leg 62: altered basalt at Site 464, at the northern end of Hess Rise; and altered... -
(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) Basalt geochemsitry at DSDP Hole 72-516F
Basalts from Hole 516F, DSDP Leg 72 on the Rio Grande Rise are tholeiitic in character but differ from normal mid-ocean ridge basalts in the South Atlantic in higher... -
(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) Geochemistry of glass shards at DSDP Leg 84 Holes
Three Leg 84 sites provided a good record of explosive volcanism onshore (in Central America). Ash layers and many ashy pods are interbedded in Recent to Oligocene strata.... -
(Table 1) Oxides and carbonates at DSDP Sample 89-585A-18-6,84-88
DSDP Site 585 was selected for drilling the Central Old Pacific as a relic of the Mesozoic superocean Panthalassa. The basal lithologic unit recovered from Holes 585 and 585A is... -
Major and trace element data for the Mehmetalan (ME), Mollatopuz (MO), and Al...
The diabases cut across the ophiolites as parallel and variably thick dyke-swarms. Geochemistry of the diabases reveals three distinct groups, including a) supra-subduction zone... -
(Table 1) Geochemistry of volcanic glass shards from tephra layers of the Gul...
The early hominids of East Africa were dated by determining the ages of tuff beds at the sites. Despite much research using palaeomagnetic and K/Ar-dating techniques, some of... -
