Liquidus thermobarometer for chromite–melt equilibrium modeling: Development and verification

详细

Liquidus chromite–silicate melt thermobarometer has been calculated by multiple linear regression of 234 experimental chromite–mafic melt equilibriums. Equations with low error reproduce the experimental compositions in a wide range of the compositions of mafic rocks, temperature, and pressure. Verification of the thermobarometers showed that the maximum error of the reproduction of the liquidus temperature is less than ±12°C. The formation equation of the cumulative chromites in the vertical section of the Burakovskii pluton was predicted with an error of ±50 m.
