| 摘 要： | 陕西略阳柳树坪金锌矿床是"勉-略-宁"三角地带碳酸盐岩型矿床,通过野外调查与地质资料分析,对该矿床的地质特征、主要控矿地质因素、成矿条件等进行了研究。研究结果表明,柳树坪矿区成矿与地层、构造、岩浆岩等多重因素有关,其中震旦系断头崖组、九道拐组碳酸盐岩富含金、铅、锌等金属矿产,是该矿床的主要矿源层;印支—燕山期形成的沿九道拐向斜南北翼发育的构造破碎带基本控制了区内矿体的空间展布;同时燕山期中酸性浅成小岩体对金、锌、铅等元素活化、富集作用较强,为重要的控矿因素。综合分析认为柳树坪矿床为沉积层控-构造热液改造型金锌矿床,具有较好的金、锌等多金属矿产资源潜力。

| Abstract: | The Liushuping gold and zinc ore deposits, located in Lueyang, Shannxi province, belongs to carbonate-type ore deposit in the "Mian-Lue-Ning" triangle zone. Through field investigation and analysis of geological data, the geological characteristics of ore deposit, the main ore-controlling geological factors and metallogenic conditions are studied. It shows that the mineralization is controlled by multiple factors of stratum, geologic structure and magmatite, and the ore bodies are hosted in Sinian carbonate of Duantouya formation and Jiudaoguai formation which are rich in gold, lead, zinc and other metals. The structural fracture zone developed along the north and south wings of Jiudaoguai syncline in the lndosinan-Yanshanian stage controls the spatial distribution of the ore bodies. The small intermediate-acid hypabyssal rock body in Yanshanian is also the important ore-controlling factor which has strong activating effect and enrichment on the elements such as gold, zinc and lead. We systematically summarize that the Liushuping gold and zinc deposit belongs to the sediment controlling- tectonic hydrothermal type, which has a good potential in polymetallic ore resources. |
