| 中文摘要: |
| 滇东富乐铅锌矿床已有300多年开采历史,目前保有铅锌资源不足,属资源危机老矿山。矿区铅锌矿层呈囊状、顺层脉状及穿层脉状赋存于中二叠统阳新组碳酸盐岩中,矿体产出层受构造、地层及岩性控制明显。通过对矿区探采资料研究分析,认为矿体在近南北向断裂两侧阳新组地层中主要呈囊状及多层顺层脉状产出,属后成中低温热液型矿床；矿区含矿地层阳新组实测平均厚度约610 m,而目前已有探采工程控制范围为阳新组顶部200 m,深部还有约400 m找矿空间；矿区北部哈播地区及西部竹园—玛强—苦木一带峨眉山玄武岩分布区之下有隐伏含矿层存在,且附近含矿地层出露区有铅锌矿化露头；第三成矿阶段黄铁矿—黄铜矿—方硫镍矿—方解石阶段在矿区深部可能形成铜镍矿工业矿体；据此认为富乐矿区深部和外围尚具较大的找矿潜力。 |
| 英文摘要: |
| The Fule lead-zinc mine has been produced for more than 300 years, currently there is insufficient lead and zinc metal resources, which resulted in the resource crisis in the Fule mine. The lead-zinc ore bodies were strictly controlled by the structure, strata and lithology, and occur in carbonate rocks of Permian Yangxin formation in forms of cystic, bedding and cross-cutting veins. Through integrated analysis of the exploration and mining data, it is concluded that the lead-zinc ore bodies occur as cystic form and bedding veins in Yangxin formation nearby the north-south trending fault, therefore it is defined as medium-low temperature hydrothermal type deposit. The average thickness of ore-hosting strata of Yangxin formation is about 610 meters in the mining area, and currently the exploration scope only covers 200 meters in the upper part of the ore-hosting formation, therefore, there is great prospecting potential in the deep part of 200 meters below the surface. In addition, the concealed ore-hosting strata occur in the Habo area, northern part of the deposit and Zhuyuan-Maqiang-Kumu in the western part of the mining area, where the basalt of Emeishan period outcropped and the lead-zinc mineralization spot outcropped in the ore-bearing strata. Also, the copper-nickel orebody may occur in the depth of the deposit area which was formed in the third mineralization stage, i.e., pyrite-chalcopyrite-vaesite-calcite sulphide stage, which indicates there is great prospecting potential in deep and margin parts of Fule lead-zinc mining area. |
