Earth's biogeochemical cycle of carbon delivers both limestones and organic materials to
the crust. In numerous, biologically catalysed redox reactions, hydrogen, sulphur, iron, and …

Elements that can occur in more than one valence state, such as Fe, C and S, play an
important role in Earth's systems at all levels, and can drive planetary evolution as they cycle …

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 …

Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes
associated with deep cycle are in the order of 1012–13gC/yr and 1022–23g C, respectively …

Owing to advances in microanalytical techniques over the last 15 years, there is a growing
database on the volatile contents of subduction-related magmas as recorded in melt (glass) …

Volcanoes are the main pathway to the surface for volatiles that are stored within the Earth.
Carbon dioxide (CO2) is of particular interest because of its potential for climate forcing …

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 …

Volcanism and metamorphism are the principal geologic processes that drive carbon
transfer from the interior of Earth to the surface reservoir. 1–4 Input of carbon to the surface …

We summarize the uptake of carbon and sulfur during serpentinization of seafloor
peridotites, and discuss the fate of these volatiles during subduction of serpentinite. We use …

Carbon and other volatiles in the form of gases, fluids or mineral phases are transported
from Earth's surface into the mantle at convergent margins, where the oceanic crust …
