摘要
Baiyangping silver-copper polymetallic ore-concentration area were developed on the northern border of the Lanping Basin,Yunnan Province. S-C-O isotopic compositions were analyzed to trace sources of ore-forming materials of the eastern ore-belt (limestone and dolomite of Upper Triassic Sanhedong Formation) and the western ore-belt (sandstone and fine-grained sandstone of Lower Cretaceous Jingxing Formation).The ore-forming fluids of the western ore-belt were hot brine of basin which may partly derived from deeper sources,and formed the Ag-Cu-Co-Pb-Zn deposit in sandstone and fine-grained sandstone of the Lower Cretaceous Jingxing Formation. The ore-forming fluids of the eastern ore-belt were paleo-meteoric water,and formed the Pb-Zn-Ag-Cu deposit in limestone and dolomite of the Upper Triassic Sanhedong Formation.
