摘要:
白石岭铅锌矿是已开采多年的危机矿山，通过一系列的勘查，在矿区外围北部发现了2条铅锌矿体，有效缓解了矿山资源危机。研究表明:新发现的2条矿体均赋存在鄌郚—葛沟断裂的次级断裂中，其形态和产状严格受断裂控制；矿体走向NNE，倾向SE，倾角55°~69°；矿体围岩蚀变发育，与成矿有关的蚀变主要有黄铜矿化、重晶石化、萤石化、硅化、方解石化等。研究区视极化率异常与矿体产出位置相吻合，且矿体深部未封闭，深部具有较好的找矿潜力。结合勘查资料，总结归纳了找矿标志，并在研究区深部圈定2处找矿靶区，为进一步找矿工作指明了方向。

Abstract:
After many years'exploitation,Baishiling lead-zinc mine is nearly depleted.A series of exploration work have found 2 lead-zinc ore bodies in the north of the periphery of the mining area,effectively mitigating the resource crisis.The study shows that both 2 newly found ore bodies occur in the Tangwu-Gegou secondary faults,and the shape and occurrence of the ore bodies are strictly controlled by the fault.The ore bodies are distributed in NNE direction,trend SE,and the dip angle is 55°-69°.The wall rock alteration of ore bodies develops,and the alteration related to mineralization mainly includes chalcopyritization,baritization,fluoritization,silicification and calcitization.The apparent polarization anomaly in the study area is consistent with the ore body output location,and the depth of the ore body is not closed,which has great prospecting potentials.Based on the exploration data,the prospecting indicators are summarized,and 2 prospecting target areas are predicted in the deep part of the study area,indicating the direction for the nextstep prospecting work in the area.
