Geochemical characteristics and genesis of the Zhubu mafic-ultramafic intrusion,Yunnan Province

摘要

1 INTRODUCTIONEmeishan large Igneous Province (ElIP) is one of the major LIPs in the world,two types of mineral deposits have been found in the intrusions:Fe-Ti-V oxide deposits in layered mafic-ultramafic intrusions,and Ni-Cu-platinum-group elements (PGE) sulfide deposits in relatively small mafic-ultramafic intrusions.The Zhubu mafic-ultramafic intrusion in Yuan-mou region host medium-sized Pt-Pd deposit.Many data on petrology and deposit has been accumulated.
