Chemical and germanium isotopic compositions of sediments and sedimentary roc...
A new technique for the precise and accurate determination of Ge stable isotope compositions has been developed and applied to silicate rocks and biogenic opal. The analyses... -
Concentrations and accumulation rates of platinum-group elements and rhenium ...
The nature of Re-platinum-group element (PGE; Pt, Pd, Ir, Os, Ru) transport in the marine environment was investigated by means of marine sediments at and across the... -
Sulfur isotope composition of ODP Site 801 in the western Pacific Ocean
The subsurface biosphere in the basaltic ocean crust is potentially of major importance in affecting chemical exchange between the ocean and lithosphere. Alteration of the... -
Trace element concentrations and Li isotope composition in DSDP and ODP sedim...
We have studied the sedimentary and basaltic inputs of lithium to subduction zones. Various sediments from DSDP and ODP drill cores in front of the Mariana, South Sandwich,... -
Chemical composition of bottom sediments at DSDP Sites 91-595 and 91-596 and ...
Subducted sediments play an important role in arc magmatism and crust-mantle recycling. Models of continental growth, continental composition, convergent margin magmatism and... -
Iron isotope and chemical compositions of sediments and basalts drilled seawa...
The purpose of this work is to study the mobility and budget of Fe isotopes in the oceanic crust and in particular during low-temperature interaction of seawater with oceanic... -
Age and chemical composition of apatites from five DSDP and ODP Sites in the ...
Since studies on deep-sea cores were carried out in the early 1990s it has been known that ambient temperature may have a marked affect on apatite fission track annealing. Due... -
Chemical, isotope and mineral composition of hydrothermally altered upper oce...
ODP Hole 801C penetrates >400 m into 170-Ma oceanic basement formed at a fast-spreading ridge. Most basalts are slightly (10–20%) recrystallized to saponite, calcite, minor...
