Within the last two decades, stable isotopes have been increasingly used in high temperature geochemistry. The capability to measure the direction and the magnitude of isotopic fractionation is essential to apply this tool to trace natural processes in geochemistry. Fields of research include the formation and differentiation of planets, such as refining the conditions of planetary core and crust formation, or processes of partial melting and crustal recycling in the Earth’s mantle using equilibrium isotope fractionation. Kinetic isotope effects, for example, related to condensation or diffusion also have been increasingly used to refine processes of planetary accretion, magmatic differentiation, metasomatism in the Earth mantle or even the time scales of magma evolution. In this session, we invite contributions from high temperature geochemists, applying experimental or modeling approaches or sample-based investigations of stable isotope fractionation in order to gain in formation on high temperature geochemical processes and time scales.
