Geochemistry and ore-prospecting targeting in Beiya area, Yunnan Province

According to the 1: 200000 geochemical data obtained from Beiya area and analysis of the enrichment regularity of main ore−forming elements of Ag, Au, Cu, Pb, Zn, the authors studied the element distribution features, anomaly characteristics, correlation and abnormal element composition, and determined the favorable prospecting composite index. Through the comparison of the typical metallogenic geological and geochemical characteristics of the Beiya gold ore district, combined with the formation, magmatite and other criteria, the prospecting area was predicted. The results show that, through an integrated study of the regional formation, structure, magmatite and mineral resources data, the establishment of the ore- forming elements anomaly zoning is feasible, which can effectively reflect the anomalies and highlight the mineralization information. According to the regional metallogenic setting of single elements Au, Ag, Pb, Zn, Cu and the combination of elements geochemical characteristics of anomalies, the target areas for further exploration were delineated, which provides guidance for ore prospecting.
