     · Host: mafic and ultramafic magma and the type of rock depends on the degree of melting and the type of country rock. Process: Magmatic intrusions result in partitioning of elements and contamination of the melt by assimilation of the host rock. Gravitation segregation of sulphur result in sulphide ore to form at the bottom of the melt.
