Magmetic sulfide deposits in the Permian Emeishan large igneous province, SW China

Abstract

Four genetic types of magmatic sulfide mineralization have been identified in the Emeishan large igneous province. These are: 1). Ni-Cu-(PGE) sulfide deposits produced by in-situ sulfide segregation, 2). PGE-enriched layers within layered intrusions, 3). Ni-Cu sulfide mineralization related to sulfide-bearing mush, and 4). PGE sulfide mineralization distributed throughout ultramafic rock. The distribution of the sulfide mineralization is associated with dynamics of the mantle plume.
