Abstract
A liquidus thermobarometer for the magnetite–silicate melt equilibrium was obtained by processing of a sample of 93 experimental equilibria of magnetite with basic melts using the methods of multidimensional statistics. The equations reproduce experimental data in a wide range of basic compositions, temperatures, and pressures with low error. Verification of the thermobarometers shows that the maximum error in liquidus temperature reproduction does not exceed ±7°C. The level of cumulative magnetite in the vertical sections of the Tsypringa, Kivakka, and Burakovskii intrusions is predicted with errors from ±10 to ±50 m.
