The prospecting effects of integrated geophysical and geochemical exploration in the Jiangjiashangou gold deposit
摘要
Abstract
The application of geophysical and geochemical anomaly characteristics and the integrated study of the evaluation criteria in the Qinling gold and lead-zinc polymetallic ore district can play the role of mutual supplement and mutual verification. Based on geo-chemical anomaly characteristics and geological environment of the exploration area, the authors hold that the major ore-forming ele-ments are Au and Ag, with the existence of the polymetallic element superimposed anomalies of Au, Ag, As, Hg, Cu, Pb, Zn, W and Mo. The magnetism is relatively low, and the ore-bearing structural alteration zone has relatively high polarizability and low apparent re-sistivity. Nevertheless, in the geological section, the orebodies mostly exhibit high resistivity and highe polarization. Based on charac-teristics of ore-related and barren anomalies, the authors established geophysical and geochemical ore-prospecting criteria for the explo-ration area. It is proved that the integrated method can yield better ore-prospecting effects in the search for structural altered rock type gold deposits in Qinling region.关键词
