(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) Chemistry of the organic matter at DSDP Leg 62 Holes
The wide distribution of sapropelic deposits in the sedimentary cover of the oceans, their Cretaceous age, and their possible oil- and gas-generating characteristics allow us to... -
(Table 1) Sr isotopes on carbonates at DSDP Hole 62-463
Study of 12 carbonate oozes from Deep Sea Drilling Project Hole 463, in the Mid-Pacific Mountains, suggests mean values of 0.70690 ± 0.00029 (2-sigma) and 0.70712 ± 0.00030... -
(Table 1) Mass-accumulation rates for the non-authigenic, inorganic, crystall...
Elevated regions in the central parts of ocean basins are excellent for study of accumulation of eolian material. The mass-accumulation rates of this sediment component appear... -
(Table 1) Mineralogy at DSDP Leg 62 Holes
Sixty-nine sediment samples of Deep Sea Drilling Project Leg 62 were mineralogically examined by X-ray diffractometry, and gasometrically for their carbonate content. Most... -
(Table 1) Distribution of ichthyolith subtypes at DSDP Hole 62-464
At Site 464, a 308-meter-deep hole was drilled on the Hess Rise (39°51.64'N, 173°53.33'E; water depth 4637 m). The upper strata consist of siliceous clay and oozes of... -
Geochemical analyses of chert nodules and beds from deep-sea sediments (Table 1)
Concentrations of Fe, Mg, Ca, Sr, Mn, Zn, and other heavy metals were analyzed by atomic absorption spectrometry in 27 chert samples from the Pacific deep sea, 17 chert samples... -
Stable carbon and oxygen isotope ratios of bulk sediment from DSDP Hole 62-46...
In order to elucidate early Aptian marine paleotemperature evolution across the period of enhanced organic carbon (Corg)-burial [Oceanic Anoxic Event (OAE) 1a], stable isotope... -
(Table 1) Chemical and lithological composition of rocks from DSDP Hole 465A
Uranium and thorium are concentrated in Cretaceous limestone, chert, ash, basalt, and other rock types at Deep Sea Drilling Project Site 465 located on the southern Hess Rise in...
