摘要
矿区位于滇黔川铅锌成矿区之巧家-金沙厂成矿带之上,处于金沙厂、茂租-东坪两大矿化集中区之间。区内震旦系灯影组上部硅质条带白云岩、顶部含藻白云岩为矿区赋矿地层,矿体呈似层状、透镜状及沿断裂带呈脉状产于以上地层中,其控矿因素为地层-岩性(相)-构造。找矿标志为灯影组上部、顶部的硅质条带白云岩、含藻白云岩,莲峰-茂租区域控矿断裂上盘和旁侧的次级断裂,相应的围岩蚀变发育的地区(段)。
The mining area is located on Qiaojia-Jingsha Chang Metallogenic belt which is between Jingsha Chang and Maozu-Dongping mineralized concentration area,Dian-Qian-Chuan lead zinc ore metallogenic region.In the mining area,the upper part of sinian Dengying formation is the siliceous zebra dolomite,the algal dolomite on the top is the ore-bearing strata of the mining area,and the ore body presents the following structure:the stratoidstructure,phacoidal structure and vein structure along the fracture zone,the ore-controlling factor is stratum-lithology(lithofacies)-structure.The prospecting indicator is the siliceous zebra dolomite,algal dolomite on the upper part and on the top of Dengying formation,and the corresponding wall rock alteration development area(region)of the subsidiary fracture's ore-controlling fracture hanging side and side spacing of Lianfeng-Maozu area.
