摘要
The Xishanwanyangchang silver deposit was discovered by means of 1∶50 000 stream sediment survey and identification of geochemical anomalies.Ag anomaly has high peaks,high values and good continuity,and anomalies of Ag,As,Sb,W and Au fit better,with concentration and component zonation.Rock geochemical profile survey was conducted in the anomaly area,distinct anomalies of Ag,Au and As etc.were discovered,and ore bodies of Ag were delineated by trench exploration.Ore bodies of Ag were identified by means of drilling,and the ore deposit is controlled significantly by faults.Rhyolite,rhyolite porphyry and rhyolite breccia are main host rocks.
