| This paper is based on previous studies, data system collection and analysis, summarized Yangbi County, Yunnan Province Fu Heng gold polymetallic metallogenic geological setting and mineralization conditions. By mining 1:10000 geological map revision and 1:10000 soil geochemical survey research, the mining geology, soil geochemical anomalies in-depth research, Delineation of prospecting targets.Studies have shown that Au mining containing seam position complex, obviously controlled by structure, mineralization type to construct the main fracture zone type, wall-rock alteration mainly silicification, limonite, pyrite and carbonates. Gold is basically a natural golden form. Geochemical parameters statistics show element, Au, Sb, As, Hg, Pb, Cu, Ag elements containing high. The content of the maximum coefficient variation of elements Au, followed by Pb; element concentration ratio of the largest element of Hg, followed by Sb. Comprehensive variation coefficient, concentration ratio index, the largest shallow mineralization is Hg, followed by the Au, reflects the region are gold, mercury mineral prospecting favorable area. Factor analysis showed that, Au, Sb, As, Hg, Pb, Cu, Ag element represents a combination of secondary enrichment mineralization element, can be used as the main indicator elements prospecting in this area; element distribution patterns show, Au, Sb, As, Hg, wide Pb, Cu, Ag element distribution, dispersion degree, reflects these elements have a strong secondary enrichment trend. Mining Au, Sb, As, Hg single element anomalies significant. The abnormality Fit, combined mining geological characteristics, exploration eligible Class A1 anomaly 1 (rock sub exception), class B 3 abnormal one (in vain Mount exception), (C) 2 (dry deer pond exception, longevity village south exception). According to soil geochemical anomalies, geological conditions, delineated three prospecting targets, namely:Mount vain, dried deer pond and rock gold prospecting targets. |
