| 摘 要： | 贵州省猪拱塘铅锌矿床位于川-滇-黔铅锌多金属成矿域东侧、紫云—垭都断裂带北西段。近年来成功运用新理论、新方法正确指导找矿勘查,发现并基本查明该矿床为一超大型铅锌矿床。通过对猪拱塘铅锌矿深部找矿工作发现,该矿床主要受NW向垭都—蟒硐断裂构造控制,容矿岩石为泥盆系上统—二叠系中统灰岩、泥灰岩、白云岩及白云质灰岩,矿体呈透镜体状、脉状和似层状赋存于断裂破碎带中,矿体在平面上部分叠合,剖面上形成平行分布的错列式矿体,具隐伏、陡倾、埋藏深、富矿段相对集中、有用组分多等特点。区内断裂构造、容矿岩性、围岩蚀变和物化探异常等可作为找矿标志。通过对猪拱塘铅锌矿床地质特征、控矿因素和找矿标志等方面的研究,认为其潜在经济价值巨大,对区域内铅锌矿找矿以及建立黔西北铅锌矿资源基地和深加工基地具有重要指导意义,为黔西北地区铅锌找矿指明了方向。这一矿床的发现对乌蒙山集中连片特困区脱贫攻坚具有深远的影响。

| Abstract: | The Zhugongtang Pb-Zn deposit is located in eastern Sichuan-Yunnan-Guizhou lead-zinc polymetallic metallogenic region and northwestern Ziyun-Yadu fault zone. In recent years, new theories and methods have been successfully used to guide the prospecting and exploration, and this deposit has been discovered and basically identified as a super large lead-zinc deposit. According to the deep prospecting of Zhugongtang Pb-Zn deposit, this deposit was mainly controlled by NW Yadu-Mangdong fracture. And the ore host rocks were the limestone, marl, dolomite and dolomite limestone from Upper Devonian to Middle Permian. The ore bodies occurred with the shape of lenticular, veins and layers in the fractured zone, partially overlapped in the plan and parallelly staggered on the section. These ore bodies were hidden, steeply and deeply buried, with relatively concentrated ore-rich section and abundant useful components. The fault structure, ore lithology, wall rock alteration, and physicochemical exploration anomaly can be used as prospecting criteria. Through the study of the geological characters, ore-controlling factors and prospecting criteria of Zhugongtang Pb-Zn deposit, the authors thought that this area has huge potential economic value, and has important guiding significance for the regional Pb-Zn deposit prospecting, and Pb-Zn resource base and deep processing base establishment. It also points out the direction for the Pb-Zn prospecting in northwestern Guizhou Province. The discovery of this deposit has a profound impact on the poverty alleviation in the contiguous poverty-stricken areas of Wumeng Mountain. |
