摘要:
笔者以大西沟热液裂隙充填型萤石矿床为例，结合地质调查，联合应用1∶5万水系沉积物测量、1∶1万土壤地球化学剖面、1∶1万高精度磁测、1∶1万高密度电阻率剖面和1∶1万电阻率剖面综合技术方法开展了萤石找矿勘查的有效性试验研究。结果表明：1∶5万水系沉积物测量工作可以缩小找矿目标区域；高精度磁测、高密度电阻率和视电阻率联合剖面物探技术方法相结合可有效地探测控矿断裂浅地表的空间延伸情况及规模；土壤地球化学剖面圈出的高F异常可有效地识别断裂构造的含矿性。将上述物探和化探综合技术方法应用到大西沟矿床外围，探测到控矿构造北西延伸至画匠沟村以北1000 m以上，并在地表发现两处矿化露头。对矿化露头经地表槽探工程揭露，浅地表矿体达工业规模，这为矿山外围深部勘查扩增工作提供了依据。同时该方法组合可为区域热液裂隙充填型萤石矿找矿工作提供一定的借鉴。
Abstract:In order to test the effectiveness of fluorite mineralization prospecting, we conducted geological survey, 1∶50 000 stream sediment survey, 1∶10000 soil geochemical profile, 1∶10000 high-precision magnetic survey, 1∶10 000 high-density resistivity profile and 1∶10000 resistivity profile in the Daxigou hydrothermal fissure filling fluorite deposit of Inner Mongolia. The results show that the 1∶50000 stream sediment survey can reduce the target area of prospecting. The geophysical exploration combination of high-precision magnetic survey, high-density resistivity and apparent resistivity profile can effectively detect the spatial extension and scale of surface ore-controlling faults. In addition, the high F anomalies in the soil geochemical profile can effectively identify the mineralization potential of the fault structure. By applying the combined geophysical and geochemical exploration techniques to the periphery of the Daxigou deposit, it is suggested that the ore-controlling structure extends to the northwest of more than 1000 m to the north of Huajianggou Village and two mineralized outcrops were found on the surface. On the basis of the surface trough exploration, it is revealed that the shallow surface ore body reached the industrial scale, which provided guidance for deep exploration in the periphyry. Furthermore, the here untilized exploration methods can provide some reference for prospecting of regional hydrothermal fissure filling fluorite deposits.
