Equilibrium oxygen, hydrogen and carbon isotope fractionation factors applicable to geologic systems
As demonstrated by the chapters in this short course, stable isotope techniques are an
important tool in almost every branch of the earth sciences. Central to many of these …

The carbon isotope geochemistry of mantle xenoliths
P Deines - Earth-Science Reviews, 2002 - Elsevier
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 …

An H2O–CO2 mixed fluid saturation model compatible with rhyolite-MELTS
MS Ghiorso, GAR Gualda - Contributions to Mineralogy and Petrology, 2015 - Springer
A thermodynamic model for estimating the saturation conditions of H 2 O–CO 2 mixed fluids
in multicomponent silicate liquids is described. The model extends the capabilities of rhyolite …

Tracking carbon from subduction to outgassing along the Aleutian-Alaska Volcanic Arc
Subduction transports volatiles between Earth's mantle, crust, and atmosphere, ultimately
creating a habitable Earth. We use isotopes to track carbon from subduction to outgassing …

13. Tracing Fluid Origin, Transport and Interaction in the Crust
We detail here the general concepts behind using noble gases as a tracer of crustal fluid
processes and illustrate these concepts with examples applied to oil-gas-groundwater …

Remobilization of crustal carbon may dominate volcanic arc emissions
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 …

Carbon and nitrogen in mantle-derived diamonds
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 …

Melting in the mantle in the presence of carbon: Review of experiments and discussion on the origin of carbonatites
T Hammouda, S Keshav - Chemical Geology, 2015 - Elsevier
Carbon emission at volcanic centers requires a constant balance between output (mostly by
volcanism, either at plate boundaries or intraplate) and input (mostly at trench settings) of …
