Abstract

Dexin lead polymetallic deposit is one of the midium-low temperature hydrothermal polymetallic deposits controlled by structure-magmatic in the western section of the Gangdese polymetallic metallogenic belt.In order to delineate the IP intermediate gradient anomaly in this area，find out the ore-forming elements combination and narrow the prospecting target area，the physical parameters of resistivity，polarizability，main and trace elements and geochemical characteristics of the rock（ore） in Dexin lead polymetallic deposit were analyzed，and the ore-forming anomalies in the mining area were comprehensively explained，and multivariate statistical analysis of ore-forming elements was carrid out.It is found that there are obvious differences in the polarization and resistivity between the orebody and surrounding rock in the Dexin lead polymetallic mining area.According to the apparent resistivity background，it can be divided into two types，namely low resistance-high polarization and high resistance-high polarization.It is speculated that the low resistance-high polarization anomalies（JD3-5，JD4）are ore-induced anomalies with deep prospecting potential，which is one of the key areas for prospecting and exploration in the area.According to correlation，R-type clustering and principal component analysis，Pb，Zn，Cu，Mo，Ni，In and other elements have significant correlation，which are the main ore-forming elements in the Dexin mining area.The Dexin lead polymetallic deposit may have experienced multiple magmatic-hydrothermal geological processes at different stages of mineralization.The early stage was influenced by Zn-Mo-Pb and Cu-Ni-In mineralization of medium-high temperature magmatic-hydrothermal mineralization type，and the later stage was affected by fluid and surrounding rock including Sc-Cr-Li and Hf-Be elements.Through the multiple stepwise linear regression analysis of the main ore-forming elements Pb，Zn，Cu and Ni，it is concluded that Pb is strongly influenced by Ni，Mo and In，Zn is strongly influenced by Mo，Cu is significantly influenced by In and Pb，and the influence degree of Ni from large to small is In，Be，Sc and Zn.According to the empirical equation，it is found that the fitting effect is good，which can provide certain microscopic information for Pb polymetallic mineralization.This understanding can provide useful macro and micro information for prospecting prediction，and has important guiding significance for comprehensive prospecting in this area.
