The Xiaosigou Cu-Mo ore deposit is a large-size porphyry deposit,and the geochemical anomalies in its periphery areas are distributed in groups and belts. Based on the summarization of metallogenic regularities and prospecting indicators as well as an analysis of such characteristics of anomalies as element association,element distribution and component zoning,this paper deals with the relationship between anomalies and mineralization and points out some ore-prospecting targets.
