Gold geochemical characteristics of Shijiba area are controlled by strata, structures and dykes developed along structures, and the major element association of stream sediment and soil anomalies is composed of Au, Hg, As and Sb. According to geological characteristics and backgrounds of different units, different anomaly thresholds were selected to delineate anomalies.Gold anomalies are characterized by large sizes, high peak values, good concentration zoning and obvious concentration centers. Engineering exposure and inspection of quite a few anomaly concentration positions led to the discovery of gold ore bodies with considerable sizes and grades, which formed Yanshan (large-sized), Xinguan (medium-sized), Houdouwan (small-sized) and Guanniuwan (small-sized) gold deposits. Ore bodies are quite consistent with anomalies, suggesting that stream sediment survey and soil survey are reliable and effective methods in this area. Based on contrast and analysis, the author holds that it is necessary to study and verify other anomalies and "weak anomalies", which may lead to the discovery of other gold deposits in this area.
