| 中文摘要:针对中国华南稀有金属矿集区植被厚、多云雾、地质环境复杂等特点，文章提出了植被覆盖区稀有金属矿床快速评价方法技术体系，通过实践探索实现了稀有金属“空、天、地”一体化快速有效探测。该体系分为3个层次，第一层次是利用多尺度、小比例尺高空光学遥感卫星厘定区域构造格架及活动期次、结合已有地质科技成果确定成矿有利区；第二层次为地表大比例尺物化探技术方法探索伟晶岩脉的空间分布及其矿化范围，利用大比例尺低空高光谱遥感反演矿化蚀变信息；第三层次利用电阻率测深和地气/X荧光探测揭示矿（化）体及其围岩地下展布特征。最后，以近年来实现找矿重大突破的湘东北幕阜山仁里矿田外围黄柏山空白区为例，阐述了此技术方法体系的有效性，以期为国内外此类地理景观区快速、高效综合探测评价稀有金属矿床提供参考。 |

| Abstract: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. |
