The Application Research On The Metallogenic Analysis And Prediction Of Typical Gold Deposits In East Kunlun Based On The Tectonic Superposition

Wu Longgou gold deposit Hong Qigou-Shen Shuitan gold deposit is located in the edge mobile belt of North tarim plate, the deposit is strictly controlled by structure. Through the analysis of the metallogenic geology and geochemical characteristics of the deposit in the study area, research on the gold deposit structural superimposed halo characteristics, models and logo by structural superimposed halo theory, established the gold deposit tectonic superimposed halo model in the study area, and having a predicated evalution for the deep of the main ore(LM8). The results showed that:1.Through the analysis of primary halo and trace element contents of the surrounding rocks and concentration zoning in the study area, the single stage mineralization primary halo axial(vertical) sequence from top to bottom is As to Sb to Hg to B; Au to Ag; Pb to Zn; Sn to W to V to Mo to Bi. Different combinations of these elements which are formed in the space display the trend of concentration zoning phenomenon, which is closely correlated with gold mineralization; Au, Ag, Cu, Zn, and Pb strong anomalies elements combination distribution and Au anomalies in the axial direction remained the same, gradually weakened to around for the center with strong anomaly combination.2. The axial zoning sequence of the superimposed halo of different periods in the study area from top to bottom in turn is Au to Pb; Zn to Mo to Hg to W to Sn to V to Sb to B; The As to Au to Ag to Bi. The Sb, B and As elements in the sequence of zoning are bias in the lower part of the ore body, which is caused by the multi-stage superimposed mineralization in the study area.3.In the different period axial zoning sequence of structural superimposed halos in the study area, strong anomalies elements Mo, V, W and Sn appear in the middle-upper part of the ore body, the front halo indicator elements Sb, B, As, Hg and Ag in the tail instead, formed the obvious zoning, and the As and Hg element change rule by high to low to high, the geochemical parameters of a reversal, illustrate the upper orebody tail halo indicator elements with ore bodies formed at the bottom of the head superposition of indicator elements, indicating an extension of the orebody in the deep there is a big blind ore or exist.In accordance with the described above, the main ore body(LM8) in the study area has great extension under 3400 m, and there is a blind ore body. After verified by drilling, all see mine in deep, the effectiveness of the structural superimposed halo model establish in the study area had a good engineering verification.
