Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

An increased ratio of 12C to 13C, an indicator of the principal carbon-fixing reaction of
photosynthesis, is found in sedimentary organic matter dating back to almost four thousand …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

We report C, Sr, and O isotopic as well as selected major and trace element data from Late
Proterozoic (ca. 540–900 Ma) marine carbonates in three widely separated basins. The …

Convective circulation of seawater through oceanic crust at mid-ocean ridges (MOR) and on
ridge flanks has wide-ranging effects on heat transport, the chemical and isotopic …

The flux of carbon into and out of Earth's surface environment has implications for Earth's
climate and habitability. We compiled a global data set for carbon and helium isotopes from …

Most of mantle carbon has δ 13 C between− 5 and− 8‰ in carbonatites, diamonds, MORB,
deep crust and subduction zones. From this, it can acquire values from− 2.5‰ in CO 2 …

Carbon occurs in mantle samples in several chemical, mineralogical and morphological
forms. It has been observed as CO2, CH4 and CO in fluid inclusions, as carbonate, graphite …

This chapter is devoted to the carbon and nitrogen stable isotope compositions of terrestrial
diamonds with a strong focus on monocrystalline diamonds formed in Earth's mantle. The …

Ion microprobe measurements of the concentrations of H2O, CO2, F, S and Cl and the
isotopic composition of hydrogen are reported for populations of olivine-hosted melt …
