THE DISCOVERY OF CU-NI SULFIDE MULTIMETALLIC DEPOSIT AT S MARGIN OF PINGBIAN-XICHOU MOUNTAINOUS ARC TERRAIN

The Nibo Cu-Ni multimetallic deposit is in the convergent area of many NW linear faults derived from the intersection of Ailaoshan terrain,Honghe fault depression trough and Pingbian-Xichou mountainous arc.The gabbroic peridotite is the rock body with Cu-Ni-Co rich ore body.According to the gravity and magnetic inference,the basic rock body is in large scale and considerable potentiality.It belongs to the type of immiscible of deep magma-simple injection Cu-Ni multimetallic deposit.
