Geochemistry of the Heishan Ni-Cu-(PGE) sulfide deposit in Gansu,NW China

摘要：

　　The Heishan Ni-Cu-(PGE) deposit is a large-size deposit with an average grades of 0.6 wt.% Ni and 0.3 wt.% Cu.Lentoid Ni-Cu sulfide ore bodies occur within the ultramific rock at the base and lower parts of the intrusion.The Heishan intrusion formed in a magma plumbing system and is a part of the magma plumbing system.Characteristics of the disseminated ores segregate that the sulfides were segregated from a PGE-depleted magma.Moreover,the disseminated sulfides in No.4 ore body likely experienced weakly monosulfide solid solution (MSS) fractionation.In contrast,the disseminated sulfides in No.1 ore body did not experience the fractionation of MSS.
