地–物–化综合方法在兴国画眉坳矿区外围深部找矿中的应用

The Application of the Comprehensive Method of Geology, Geophysical and Geochemical in the Deep Prospecting of the Periphery of the Huamei'ao Mining Area

摘要: 研究区处于南岭东西向构造–岩浆岩带东端与武夷山隆起带西侧之雩山坳陷带交汇部位，成矿区带属南岭成矿带东段之雩山成矿亚带，矿业又是县域经济支柱性产业，画眉坳钨矿山作为当地主要的矿山企业之一，资源已严重消耗枯竭，矿区外围接替资源勘查找矿工作迫在眉睫，寻找深部及隐伏矿。本次通过化探、高精度磁法、激电中梯、激电测深测量，结合地质调查研究成果，认为画眉坳矿区外围具有较好的寻找、评价石英脉型钨多金属矿资源潜力，进一步综合已有区域地质、重力资料，可取得良好的找矿效果。

Abstract: The study area is located at the intersection of the east end of Nanling East-West structural magmatic belt and Yushan depression belt on the west side of Wuyishan uplift belt, belonging to the Yushan metallogenic subzone in the eastern part of Nanling metallogenic belt. The area has a large number of poor people for a long time, and mining industry is the pillar industry of county economy. However, as one of the main local mining enterprises, the main tungsten beryllium ore resources in Huamei'ao mining area have been consumed and exhausted. Therefore, it is urgent to carry out the exploration work of substitute resources in the periphery of the mining area, and then gradually turn from the search for surface or shallow mines to the search for concealed and deep mines. In this work, geochemical exploration, high-precision magnetic method, IP middle ladder and IP sounding survey have been carried out. Combined with the geological survey and research results, it is considered that the surrounding area of the Huamei'ao mining area has a good potential to find and evaluate the quartz vein type tungsten polymetallic ore resources, and if the existing regional geological and gravity data were integrated, great prospecting results can be obtained.
