| Abstract:Through 1:50000 high-precision magnetic survey performed in Puchiya area, the authors acquired a detailed understanding of the characteristics of the magnetic field. On the basis of a qualitative analysis of magnetic anomalies, 11 potential anomaly areas for ore prospecting were recognized through screening. Meanwhile, 1:50000 regional stream sediment survey shows that the main metallogenic elements are Cu, Pb and Zn. Qualitative analysis of magnetic anomalies of these metallic deposits can provide favorable evidence for ore-prospecting work at depth. In combination with geochemical anomalies, geological characteristics, optimized magnetic anomalies, three best magnetic anomaly districts were delineated through optimization, namely Zhanzanmubu-Kengmalejian high-intensity magnetic anomaly district, Seyao high-intensity magnetic anomaly district, and Yageruo weak-intensity magnetic anomaly district. Ore-prospecting orientations in these three districts are also indicated in this paper. |
