THE DISCOVERY OF THE BEIDAGOU GOLD DEPOSIT IN HEIHE CITY: A CASE OF SUCCESSFUL GEOCHEMICAL SURVEY

he Beidagou gold deposit in Heihe City,lying in the southeastern part of the Da Hinggan Ling Yanshanian metallogenic belt,is a quartz vein type gold deposit discovered by geochemical survey in the periphery of the Sandaowanzi gold deposit.Through a comparison of geochemical characteristics with the Sandaowanzi gold deposit,this area was chosen as a prospecting target to conduct soil geochemical survey.Quite a few Au,Ag,As,Sb,Cu,Zn and Mo anomalies were delineated,with Au,Ag,As,Sb and Mo anomalies being dominant.The anomaly concentration centers of various elements are quite consistent with each other.Anomaly inspection led to the discovery of the Beidagou gold deposit,which shows that the target selection was fairly successful,and the geochemical survey is effective in the ore-prospecting work of this area.
