| Abstract: | Based on the geochemical survey of stream sediment in eastern Laji Mountains,Qinghai province,the composite anomalies of stream sediment of the elements such as Au, As,Ag,Bi ,Sb,Hg,etc are discovered in Jinyuan, Lamamiao and Qixingsixia.
In where the developed shape,distribution and anomalous concentration center of the elements such as Au, Ag,As relatively high concentration zone are proximately coincident,the Au,Cu orebodies and Au mineralization area are discovered. The characteristics of geochemical anomaly of the areas are similar to those of Nidangou Au ore deposits discovered in this region,and the prospective areas of the copper ,gold mineralization are revealed. |
