Transitional metal elements are useful for understanding the Earth's formation processes. Those with more than one oxidation state can be used to constrain the variations and evolution of redox state of the mantle over time. Moreover, elements with more than two isotopes can also be studied for their isotopic compositions and provide even more constraints on such processes. Chromium is one of these elements: it is present under at least two (Cr2+ and Cr3+) redox states in the Earth mantle and has four stable isotopes (50Cr, 52Cr, 53Cr and 54Cr). During partial melting and fractional crystallisation, chromium behaves compatibly and temperature and oxygen fugacity are the main factors controlling its behaviour. Furthermore, it has been shown that oxygen fugacity plays a role in controlling Cr isotopes fractionation between chromites and silicate melts. We investigated the impact of temperature as well as pressure on such fractionations. Piston-cylinder experiments were carried out at constant pressure (1 GPa) and varying temperature (from 1250 °C to 1500 °C). In order to vary oxygen fugacity two different capsules (Au-Pd and graphite) were used. The experimental samples, synthesised from a primitive MORB and a natural spinel, show Cr2O3 contents in the liquid increasing with temperature. The same correlation can be observed with oxygen fugacity. The Cr contents of chromite at equilibrium with silicate melt increase with increasing temperature and oxygen fugacity. In light of these results, chromium becomes less compatible at high temperature and low fO2 in agreement with previous studies. By comparison with former experiments at atmospheric pressure, our results indicate that pressure does not strongly influence chromium behaviour. Measuring the Cr isotopic compositions of silicate melts and chromites at equilibrium will enable us to assess the potential of Cr stable isotopes as a redox proxy during mantle processes.
