Establishment and application of rapid detection and evaluation system for rare metal ore clusters in vegetation coverage area of South China

Aiming at the characteristics of thick vegetation, multiple shadows, and complex mountains in the rare metal ore concentration areas in South China, a technical system for rapid evaluation of rare metal deposits in vegetation coverage areas was proposed. Through practical exploration, the integration of "air, space, and earth" was quickly and effectively detected. The system is divided into three levels. The first level is multi-scale remote sensing. Specifically, small-scale regional high-altitude optical remote sensing satellites determine regional tectonic patterns and activity periods, combined with existing geological scientific and technological achievements to determine favorable mineralization areas, and use large-scale low-altitude inversion of mineralization and alteration information by hyperspectral remote sensing; The second level is the application of effective methods and techniques for large-scale geophysical and geochemical exploration on the surface, combined with remote sensing mineralization and alteration information to comprehensively determine the area distribution and mineralization range of pegmatite veins; The three levels use apparent resistivity sounding and ground gas detection to determine the underground distribution characteristics of the mineralized body and its surrounding rock. Finally, taking the Huangbaishan blank area outside the Mufushan Renli ore field in northeast Hunan that has achieved major breakthroughs in prospecting in recent years, the effectiveness of the technical system of this method is explained, and it is expected to provide rapid and high-quality detection for such geographic landscape areas at home and abroad reference for evaluating rare metal deposits.
