Analysis of geophysical-geochemical methods lead to Hala River Pb Multi-Metal mine prospecting guiding significance

On the basis of previous research, through the system summary of field work, this paper describes the Hala river Pb multi-metal mine's geological characteristics, geochemistry characteristics, geophysics characteristics. Combined with the results of the census prospecting stage, brief analysis of the guidance geophysical and geochemical prospecting method throughout the process of prospecting in Inner Mongolia Zhalantun Hala river Pb multi-metal mine, guide further prospecting. Hala river Pb multi-metal mine elements mainly silver, copper, lead, zinc. Ore located in the Middle Jurassic Tamulangou andesite and early Yanshan granite porphyry intrusive contact zone around it. According to the results of geophysical and geochemical completed in mining ore deposit show significantly different with the surround rock. Through the analysis of various geophysical and geochemical anomalies discussed, against its geological environment. Combined with drilling to verify the results. Analysis of the abnormal genesis and deposits, ore distribution of mutual relations. While summed comprehensive geochemical, geophysical prospecting indicators. Presumably cause of ore is low temperature hydrothermal Pb-Zn-deep porphyry copper mineralization system. (authors)
