Abstract:In order to evaluate the ore-forming potential of strata and rock mass in the East Yanchi area of the Beishan metallogenic belt, a comparative systematic geochemical analysis is carried out on the basis of spectral analysis data of petrochemical elements in strata and rock mass. The ore-forming element enrichment factor (K), the late superposition intensity (D), and the ore-forming elemental coefficient of variation (CV) were analyzed for its minerality. The results are as follows: the analysis of K indicates that Pb, Au, Ag, Co, W, Bi, P, V and other elements are significantly enriched in this region, and the metallogenic potential is huge; D analysis shows that there is a strong superposition of Pb, W, and Au in this area; the analysis of CV indicates that Pb, W, Au, Co, Bi, Zn, etc. in strata and intrusive rocks in the East Yanchi area have strong variability. According to the comprehensive evaluation of the ore-forming ability of strata and rock mass in this area, the most dominant minerals in the East Yanchi area are Pb, Au, W, Ag, P, and V. The Gudongjing group in the Great Wall is the main ore-bearing stratum of Pb; the Shuangyingshan formation and the Xishuangyingshan formation of Cambrian are the main ore-bearing horizons of P and V; the Cambrian, Mesoproterozoic strata, and the Middle Cambrian and Late Carboniferous intrusive rocks are the main elements of W, Au, Ag, etc.
