FEATURES OF GEOCHEMICAL ANOMALIES AND ORE PREDICTION IN XIAOSHIREN GOLD DEPOSIT, JILIN PROVINCE

Xiaoshiren gold deposit is of Au,Ag,Cu,Pb,As,Sb,Hg and Bi anomalies on regional, deposit and lode scales. The intersecting parts of the EW and NNE trending structures are the most favorable sites for gold mineralization. There are three anomalous zones around and adjacent to the deposit, but the known lodes are all located in the northern anomalous zone, and the middle and southern anomalous zones are lack of gold mineralization. Ag, As, Sb, Hg and Ba are head halo elements, and Bi, Cu and Co are the rear elements in one lode. Based on the zoning index of the indicative elements, it is suggested that it is quite possible to find some blind ore bodies at the depth of No.1 lode, and it is unlikely to find any blind ore body at the depth of No.2 lode. 
