摘　　要：西山头地区位于宁镇铜铅锌多金属成矿带西段,区域成矿地质条件优越,以往的区域地质调查工作发现了较好的找矿线索,但未能引起足够的重视。为了剖析研究区的成矿条件,开展了地质调查、化探调查、激电中梯、高精度磁测、可控源音频大地电磁测深和激电测深研究。结果显示:研究区具有与栖霞山铅锌矿床类似的双构造层,具备寻找栖霞山式铅锌矿的条件;区内逆冲推覆体下部的构造不整合面、石炭—二叠纪碳酸盐岩地层中的纵向断裂是研究区主要的赋矿位置,也是未来重要的找矿方向。The Xishantou area is located in the western part of Cu-Pb-Zn polymetallic metallogenic belt of Ningzhen and has excellent metallogenic geological conditions.Good prospecting clues have been found in previous surveys,but not enough attention has been paid to them.Geological survey,geochemical survey,IP intermediate gradient method,high precise magnetic survey,CSMAT and IP sounding have been applied to research the ore-forming conditions of the study area.The study area has double structural plane of unconformity similar to Qixiashan lead-zinc deposit,which is qualified to find Qixiashan type lead-zinc deposit.The structural plane of unconformity in the lower part of the thrust nappe,and the vertical fracture in the Carboniferous to Permian carbonate rock strata,are the main ore-bearing strata and prospecting directions for mineral exploration.
