| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
