Total organic carbon, delta13C, biomarker, diatom distributions in sediment c...
In the light of rapidly diminishing sea ice cover in the Arctic during the present atmospheric warming, it is imperative to study the distribution of sea ice in the past in... -
(Table 1) Carbon and isotopic composition of organic carbon in sediments from...
We have analyzed inorganic and organic carbons and determined the isotopic composition of both sedimentary organic carbon and inorganic carbon in carbonates contained in... -
(Table 3) Temporal variations in areal nitrogen fixation rate from monthly sa...
Areal rates were calculated from 15N2 uptake measurements for at least four depths (three replicates per depth) and integrated from surface to 150 m depth. Also presented are... -

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 1) Organic geochemistry at DSDP Leg 71 Holes
Forty-three core samples from Sites 511 through 514 of DSDP Leg 71 were analyzed geochemically. The black shales at the bottom of Hole 511, in the basin province of the Falkland... -

Qualitative petrographic study of selected clastic horizons within the Eocene section of Hole 516F has revealed the presence of abundant fine-grained lithic fragments, probably... -
(Table 1) Interstitial water chemistry at DSDP Leg 76 Holes
Low salinities and strong opposing fluctuations between chlorinity and interstitial water d18O and dD characterize the region of gas-hydrate occurrence at Site 533. In addition... -
(Table 1) Concentrations and carbon isotopic compositions of CH4 and CO2 at D...
The principal gaseous carbon-containing components identified in the first 400 m of sediment at Deep Sea Drilling Project Site 533, Leg 76, are methane (CH4) and carbon dioxide... -
(Table 1) Sulfur content and sulfur-isotope ratios at DSDP Leg 82 Holes basalts
The sulfur contents of 21 basalt samples from four DSDP Leg 82 holes were determined and the isotopic compositions of sulfur were measured on 15 of them. Most of the basalts are... -
(Table 1) Lead isotopic composition and concentration at DSDP Leg 82 Holes
The aim of DSDP Leg 82 was to decipher the temporal and spatial evolution of Azores Plume. The Pb-isotopic results of this leg are rather complex, and can be summarized as... -
(Table 1) Downhole variation of potassium, apparent K-Ar age, and inert gas a...
Ne, Ar, Kr, Xe, and K2O were measured in representative samples of holocrystalline basalt from DSDP Hole 504B. No hiatus in inert gas abundance is recognized at the base of the... -
(Table 1) Stable carbon isotopic composition of CH4 and CO2 of DSDP Leg 84 Holes
Interstitial gases were collected from Holes 565, 566, 567A, 568, 569A, and 570 drilled during Deep Sea Drilling Project Leg 84 on the Glomar Challenger. The samples were... -

Studies on He isotope ratios of gas and rock samples in various parts of the world have shown a close relation between the 3He/4He ratio and geotectonic features of the sampling... -
(Table 1) Potassium, radiogenic Argon 40 and dated age for DSDP Hole 94-608 s...
K-Ar dates were obtained for three pillow basalt samples recovered from Site 608 (Samples 608-58-1, 103-109 cm; 608-59-1, 3-7 cm; 608-59-1, 48-53 cm). Reliable K-Ar dates cannot... -
Isotopic-geochemical features of spontaneous gases from mud volcanoes in East...
Isotopic-geochemical study revealed presence of mantle He (3He/4He up to 223x10**-8) in gases from mud volcanoes of Eastern Georgia. This fact confirms that the Middle Kura... -
