摘要
全州县上塘村铅锌矿位于南岭成矿带桂东北,矿床产于中泥盆统棋子桥组(D2q)碳酸盐岩地层中,矿体赋存于构造复合部位的旁侧破碎带及层间裂隙中,具多期矿化特点。文章在全面分析了矿床成矿地质条件、矿石结构构造、矿石物质组成及围岩蚀变的基础上,认为该矿床成矿作用主要表现为地下热水成矿作用、岩浆热液成矿作用及岩浆热液叠加成矿作用,最后总结了五点找矿标志,为矿区深部及外围找矿提供帮助。
The Shangtang village lead and zinc deposit in located in northeast area of Guangxi which form part of Nanling ore belt, and the ore deposit occurs in carbonatite rock strata of the Qiziqiao group （D2q） in mid- dle Devonian system while orebody occur in the side fractured zones and inter-layer fissures of tectonic com- posite part, characterized by multi period mineralization. Based on the comprehensive analysis on ore-form- ing geological condition, ore structure and texture, ore matter composition and country rock alteration, it is believed that the mineralization of the deposit is mainly characterized by underground hot fluid mineraliza- tion, magmatic hydrothermal mineralization and superimposition of magma and hot fluid mineralization. 5 ore prospecting indicators were summarized at the end for the ore prospecting in depth and periphery of the deposit.
