【摘要】 丁头山铅锌矿床位于贵州省黔西南赫章—威宁—水城铅锌矿成矿带东北部，为黔西南铅锌成矿带的重要组成部分。铅锌矿体赋矿围岩为马平组（Cpn）第二段致密块状含燧石结核灰岩，受花贡断层（F₃）和丁头山逆断层（F₁）控制。本文在梳理前人研究成果的基础上，对矿床地质特征及地质条件进行分析，通过对比黔西北地区铅锌矿床成矿特征，确定了马平组第二段+NW向区域构造+围岩蚀变在内的找矿标志，综合激发极化法物探成果，圈定的异常区找矿效果显著，对区域内同类成矿条件地区铅锌矿找矿勘探有一定的借鉴价值。更多还原

【Abstract】 Dingtoushan lead-zinc deposit is located in the northeast of Hezhang Weining Shuicheng lead-zinc metallogenic belt in Southwest Guizhou Province. It is an important part of Southwest Guizhou lead-zinc metallogenic belt. The host rock of lead-zinc ore body is dense massive chert nodule limestone of Mapping formation（Cpn）, which is controlled by Huagong fault（F₃） and Dingtoushan reverse fault（F₁）. On the basis of combing the previous research results, this paper analyzes the geological characteristics and geological conditions of the deposit, compares the metallogenic characteristics of lead-zinc deposits in Northwest Guizhou, and determines the prospecting indicators including the second member of Mapping formation+NW trending regional structure+wall rock alteration. Based on the geophysical exploration results of induced polarization method, the prospecting effect of the delineated abnormal area is remarkable, This paper has reference value for lead-zinc ore prospecting and exploration in areas with similar metallogenic conditions in the region.更多还原
