摘要
This paper discussed the gold geochemistry feature of this area. The results of 1∶50 000 stream sediment survey and 1∶10 000 soil survey show that the Au anomalies is characterized by large area, high peak and fine zoning of concentration, good anomalous association of Au, As, Ag, Hg, Sb. The soil survey was employed to reduce the exploration target, and the ore body has been determined. By comparison and analysis, it is clear that the systemic prospecting in this area should be the main method, by 1 ∶50 000 stream sediment survey for outlining anomalies, and 1∶10 000 soil survey for reducing target.
