| The Baoshan copper-lead-zinc orefield is an important orefield in the southern Hunan ore-concentration area. In order to explore the applicability of the tectonic geochemical prospecting method in the mineral exploration of the deep and margin of the deposit, this paper takes the Caishenmiao lead-zinc deposit in the northern part of the Baoshan ore.eld as an example. Based on the .eld tectonic investigation, the tectonic geochemistry research was carried out in the middle section of -110m and -190m, and the geochemical data of 208 tectonite samples were obtained. The cluster analysis and factor analysis, and the abnormal delineation of the factor contour map of the elements show that the two middle element factors are classi.ed similarly, and all of results have the factors related to the combination of granodiorite porphyry elements (Nb, Th, Ga, Ge , Be, Sc, Ta, Cs, Rb, Ba, REE, etc.), factors combined with high and medium temperature ore-forming elements (Pb, Zn, Cd, Ag, In, Cu, W, Sb, Bi, Sn, As), factors combined with low-temperature mineralization elements (Hg, Au, As, Tl). According to the scores of each mid-section factors, 13 anomalies were delineated, and 2 prospecting prediction areas were proposed by comprehensive analysis. It is considered that tectonic geochemistry is of great signi.cance to the exploration of deep and margin orebodies of hydrothermal deposits in southern Hunan. |
