The COMAGMAT-5: Modeling the effect of Fe-Ni sulfide immiscibility in crystallizing magmas and cumulates

Abstract

1000ppm. In addition, using an experimentally studied highmagnesia andesite composition, the results of calculations with two versions of COMAGMAT (3·72 & 5·2) were compared with those produced by MELTS family models. Application examples of COMAGMAT-5 include the modeling Fe-Ni sulfide saturation during equilibrium and fractional crystallization of ultramafic systems, approximating the most primitive magmas and cumulates from the Bushveld Complex in South Africa.
