THE STUDY ON REGIONAL TECTONICS OF JINYING GOLD ORE IN BAISHAN CITY,JILIN PROVINCE

The structures of Jinying gold mine are divided into five tectonic zones by detailed field work and indoor analysis,i.e.,NE,NW,EW,NNE,SN.These structures belong to five different tectonic systems:Cathaysian system,NW tectonic zone,EW tectonic zone,Neocathaysian tectonic system,SN tectonic zone,whose tectonic evolutionary track is as following:Cathaysian→NW tectonic zone→EW tectonic zone→Neocathaysian→SN tectonic zone.The study indicates that the Cathaysian system is the major structures in the study area,and gold mineralization lies in the NW tectonic zone which distributes along the NE tectonic.In other word,the mineralization occurs in the intersection zone of NW and NE tectonic.
