Three decades after the discovery of cold seep systems, various sites of hydrocarbon
seepage have been found in the South China Sea (SCS). Over the past decade, these sites …

The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Traditional stable isotope geochemistry involves isotopes of light elements such as H, C, N,
O, and S, which are measured predominantly by gas-source mass spectrometry (Valley et al …

Stable carbon and oxygen isotopes (δ18O and δ13C values) and trace elements have been
applied to the study of diagenesis of carbonate rocks for over 50 years. As valuable as these …

Calcium carbonate formation is the primary pathway by which carbon is returned from the
ocean–atmosphere system to the solid Earth,. The removal of dissolved inorganic carbon …

Calcite growth experiments have been performed in the presence of aqueous Mg at 25° C
and 1bar pCO2 to quantify magnesium partition coefficient DMg=(Mg/Ca) solid (Mg/Ca) fluid …

In order to better understand the effect of CO2 on the Earth system in the future, geologists
may look to CO2-induced environmental change in Earth's past. Here we describe how CO2 …

Different approaches are used to study wood provenance, but most of them are based on
tracers in wood that are generally controlled by climatic factors. The strontium isotopic ratio …

Geochemical variations in marine biogenic carbonates that are preserved in the geological
record serve as proxies of past environmental change. However, interpreting most proxies is …

Natural variations in the isotopic composition of some 50 chemical elements are now being
used in geochemistry for studying transport processes, estimating temperature …
