摘　　要：山西省相对缺乏铅锌银矿产,为加大对山西本土铅锌银矿产资源的综合利用,文章结合物化探方法对吕梁市方山县黄圈塔铅锌银矿的矿床地质特征进行研究。研究结果表明,该铅锌银矿体主要受断层破碎带控制,呈脉状产出,通过激电法对矿(化)带进行形态追踪,显示出矿(化)带具有相对较高的视电阻率和极化率异常,异常空间位置与F 1断层位置基本一致,异常体向深部延伸并逐渐转向西南。沿矿带走向上,Pb、Zn、Ag以及其他金属元素地球化学组合异常明显,异常长轴约300 m,长轴方向与激电异常基本一致。矿石自然类型为赤铁矿化铅锌矿氧化矿石,矿床成因类型属于热液蚀变破碎带层控型矿床。找矿时应多关注高角度断裂构造破碎带、构造角砾岩、地层内发生的碳酸盐化、褐铁矿化,同时也是地表找矿的直接标志。In order to increase the research and utilization of local Pb-Zn-Ag mineral resources in Shanxi Province,the geological characteristics of Huanghuanta Pb-Zn-Ag deposit in Fangshan County,Lüliang City is studied for the first time by the combination of geophysical and geochemical exploration method.The result shows that the lead-zinc-silver ore body is mainly controlled by the fracture zone of the fault and is produced in a vein-like form.The morphological tracing method of the mineralization zone shows that the it has relatively high resistivity and polarization rate anomaly and coincides with the location of F 1 fault,which gradually turns downward to the southwest.The geochemical combination anomaly of Pb,Zn,Ag and other metal elements is 300 meters long in the striking direction.The natural type of ore is hematite Pb-Zn oxide ore,and the deposit genesis type belongs to the hydrothermal alteration and fractured zone layer-controlled deposit.High angle fracture zone,structural breccia,carbonation and limonite should be paid more attention to in prospecting,which is also a direct sign of surface prospecting.
