Element concentrations and stable oxygen and carbon isotope ratios of basalts...
A detailed microbiological and geochemical study related to the alteration of basaltic glass of pillow lavas from the oceanic crust recovered from Hole 896A on the Costa Rica... -
Isotopic composition of carbonates from the Logachev Hydrothermal Field, MAR ...
We investigate the Logatchev Hydrothermal Field at the Mid-Atlantic Ridge, 14°45' N to constrain the calcium isotope hydrothermal flux into the ocean. During the transformation... -
Uranium concentrations and isotope ratios Bahamas seawater and ODP holes pore...
The geometry, timing, and rate of fluid-flow through carbonate margins and platforms is not well constrained. In this study, we use U concentrations and isotope ratios measured... -
The alkali element and boron geochemistry of ODP Site 169-1038 in the Escanab...
A suite of conjugate pore fluid and sediment samples were collected during Leg 169 of the ODP from within the clastic sedimentary sequences which host massive sulphides at... -
Clay mineralogical assemblages, Sm-Nd concentrations, Sm and Nd isotopic rati...
We present 40 Sm-Nd isotope measurements of the clay-size (<2 µm) fractions of sediments from the Southern Greenland rise (ODP-646) that span the last 365 kyr. These data... -
Mineralogical and isotopic compositions of ODP Hole 107-650A
Red-brown dolomitic claystones overlay the Marsili Basin basaltic basement at ODP Site 650. Sequential leaching experiments reveal that most of the elements considered to have a... -
Concentrations and isotopic ratios of thorium and uranium in pelagic sediments
The predictable in situ production of 230Th from the decay of uranium in seawater, and its subsequent removal by scavenging onto falling particles, provides a valuable tool for... -
Neodymium isotope composition of planktonic foraminifera from ODP Hole 121-758A
This study presents neodymium isotope and elemental data for cleaned planktonic foraminifera from ODP site 758 in the southernmost reaches of the Bay of Bengal in the north-east... -
Element concentrations and Osmium, Platinum and Rhenium isotope ratios of ODP...
Abyssal peridotites are normally thought to be residues of melting of the mid-ocean ridge basalt (MORB) source and are presumably a record of processes affecting the upper... -
Oxygen and carbon isotope ratios of silicates and carbonates from exhumed per...
Legs 173 and 149 of the Ocean Drilling Program profiled a zone of exhumed mantle peridotite at the ocean-continent transition (OCT) beneath the Iberia Abyssal Plain. The zone of... -
Composition of drilled sediments and pore waters from the continental slope o...
Pore waters were analyzed from 6 holes drilled from M.V. “Eureka” as a part of the Shell Oil Co. deeper offshore study. The holes were drilled in water depths of 600-3000 ft.... -
Calcium isotopic composition of planktonic foraminifera from ODP Site 154-925
An 18 million year record of the Ca isotopic composition (d44/42Ca) of planktonic foraminiferans from ODP site 925, in the Atlantic, on the Ceara Rise, provides the opportunity... -
Nd, Sr and Pb isotopic composition of eolian dust deposited in the central No...
The silicate fractions of recent pelagic sediments in the central north Pacific Ocean are dominated by eolian dust derived from central Asia. An 11 Myr sedimentary record at ODP... -
Osmium isotopic composition and platinum group element concentrations in sedi...
Paired analyses of Os isotope composition and concentration of bulk sediment and leachable Os in a metalliferous pelagic clay sequence from the North Pacific, ODP Site 886C, are... -
Nitrogen isotopic composition and chemical composition of altered oceanic cru...
Knowledge of the subduction input flux of nitrogen (N) in altered oceanic crust (AOC) is critical in any attempt to mass-balance N across arc-trench systems on a global or... -
Calcium concentrations and isotopic composition in carbonates and porefluids ...
The calcium isotopic compositions (d44Ca) of 30 high-purity nannofossil ooze and chalk and 7 pore fluid samples from ODP Site 807A (Ontong Java Plateau) are used in conjunction... -
Chemical composition of altered volcanic rocks from ODP Sites 193-1188 and 19...
The conventional model of leaching volcanic rocks as a source of metals in a seafloor hydrothermal systems has been tested by examining the behavior of Pb and other trace... -
Lithium isotopic composition of pore fluids and sediments in the Costa Rica s...
Pore fluid and sediment Li concentrations and isotopic ratios provide important insights on the hydrology, sediment contribution to the arc volcanoes and fluid-sediment... -
Boron concentrations and isotope ratios of authigenic carbonates from the Ore...
Boron contents and boron, carbon and oxygen stable isotopes were determined for authigenic carbonates recovered from Ocean Drilling Program Leg 146, Oregon margin. Carbonate... -
Boron isotope ratios of samples from ODP Leg 125 sites at a serpentine seamou...
Serpentinite clasts and muds erupted from Conical Seamount, Mariana forearc, show substantial enrichment in boron (B) and 11B (delta11B up to +15 per mil ) relative to mantle...
