| 中文摘要: |
| 赫章猪拱塘铅锌矿床为最近查明的-超大型铅锌矿床，位于川-滇-黔铅锌多金属成矿域，黔西北铅锌矿集区北东侧。本文在分析前人资料基础上，结合野外地质调查显示，矿区地处垭都-蟒硐断裂带北西段，主要发育古生代地层和呈北西向、北东向两组断裂。矿体受北西向断裂构造控制，受岩性控制明显，矿体主要赋存于断裂带内。主要矿石矿物为闪锌矿、方铅矿和黄铁矿，矿石组构类型主要有粒状结构、交代结构、包含结构、压碎结构，块状构造、浸染状构造、脉状构造以及条带状构造。围岩蚀变白云石化、方解石化、黄铁矿化、硅化、重晶石化和褐铁矿化，矿床成因类型属中低温热液型矿床。该矿床的发现改变了黔西北地区铅锌矿的找矿思路，对指导黔西北地区铅锌找矿具有重要指导意义。 |
| 英文摘要: |
| The Zhugongtang Pb-Zn deposit is a Ultra-large Pb-Zn deposit recently identified, located in the Sichuan-Yunnan-Guizhou polymetallic metallogenic lead-zinc region, north east of the pb-zn concentration area in northwest guizhou. Based on the analysis of previous data avail-able in combination with field geological survey,the deposit is located in the northwest section of Yadu-Mangdong fault zone, The paleozoic strata are mainly developed,tow main fault systems are northwest striking faults and north east-striking faults.The ore bodies are developed in the fractured zone,All ore bodies are controlled by northwest fault structured and obviously controlled by lithology.The main ore minerals are sphalerite, galena and pyrite, The rock fabric types mainly include granular, metasomatic, inclusion and crushing structure,block, disseminated, vein and band structure.The alterations of the host rock are mainly dolomization, calcite, pyritization, silicification, barite and limonite,the deposit belongs to the medium and low temperature hydrothermal deposits.The discovery of this deposit has changed the thought of Pb-Zn deposit prospecting in northwestern guizhou, and has important guiding significance for Pb-Zn deposit prospecting in northwestern guizhou. |
