Abstract: Pulang Copper Mining Area is a super large deposit in ThreeRiver metallogenic belt,which characterized by superior oreforming geological conditions.However,the southern and periphery of Pulang mining area has the low research level,by limited to complicated geographical environment.Through the geochemical survey,the anomaly shape and enrichment regularity of element are analyzed.Besides,the polymetallic mineralization and mineralization regularity are redefined,and further defined the prospecting direction.The research results show that the anomaly elements of soil geochemistry mainly includes Ag,W,Zn and Au,which overlap occurred by zonal distribution and flake distribution;four comprehensive anomalies,which including AuAsAgW (HS1),AuWCuAsMoAg (HS2),ZnHgAsWSb (HS3) and AuAsZnHgWSb (HS4) are delineated;the HS2 anomaly belt is highly consistent with magmatic rock and sedimentary rock contact zone,which characterized by superior orecontrolling condition and orecontaining condition,the gold orebed which exposed by borehole engineering can be regarded as the favorable position to find gold polymetallic mineralization/ore-bodies.
