| 中文摘要: |
| 铁炉坪银铅矿床位于河南省洛宁县下峪乡,矿区内发现6条蚀变破碎带,共圈出24个银矿体和7个铅矿体。矿体赋存于太古宇太华群石板沟组地层中,严格受北北东向断裂控制,形态以脉状、透镜状为主。通过对铁炉坪银铅矿床地层、构造、岩浆岩及围岩蚀变等地质特征研究,认为矿体受花岗绿岩带及构造断裂带的联合控制,并受后期热液叠加改造,属海底火山喷发—变质热液改造块状硫化物型矿床。归纳总结其找矿标志,对熊耳山地区寻找同类型矿床具有指导意义。 |
| 英文摘要: |
| Tieluping silver-lead deposit is located in Xiayu, Luoning County, Henan Province. Totally 24 silver ore bodies and 7 lead ore bodies were outlined within the six altered fracture zone in the deposit area. The ore bodies were hosted by Shibangou formation strata of Achaean Taihua group, which was strictly controlled by NNE faults and characterized with forms of bedding and lens. Based on the study of geological characteristics in Tieluping silver-lead deposit such as stratum, structure, magmatic rocks and wall rock alteration, the authors pointed out that ore body was controlled by granite greenstone belt and tectonic fault zone and then superimposed by late stage hydrothermal fluids, the genesis of the deposit belongs to the submarine volcanic eruption sulphide type and reformed by the metamorphic process. Through summarizing the prospecting criteria in the deposit area, it is significant for exploring the similar type of sulphide deposits in the Xionger Mountain region. |
