is located in the Ondor Sunm Caledonian accretionary belt of eastral Asian Orogenic Belt. There are two tupes of the ore: Cu-bearing lodes and altered ores occurred in the magmatite of Hercynian and the green schist of Bainaimiao group. Mining area stratum is mainly the Qingbaikouan Bainaimiao group and the quaternary Holocene. The main Wall-rocks altered include silieifieation
baritization(limonitization)
sericition
chlorition
kaolinition
carbonatization. Previous studies found that Bainaimiao gold deposit is a control structure
