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

Abstract: 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.
