摘要

勘查区处在红柳沟-拉配泉元古代裂谷带,属于阿尔金-阿克塞金、铜、铁、锰、稀有、稀土、石棉、蓝晶石、白云母成矿带。所圈定铅锌矿体均产于构造破碎带,受断裂构造控制,矿体主要赋存在上奥陶统拉配泉群第二岩组碎裂英安岩中,蚀变矿化有硅化、高岭土化等,赋矿岩石为碎裂英安岩,矿石结构有粉末状、胶状,构造有薄膜状、细脉状等。
        The exploration area is located in the Hongliugou-Laisquanquan ancient rift zone, belonging to the AltunAkesaijin, copper, iron, manganese, rare, rare earth, asbestos, kyanite and muscovite metallogenic belts. The lead-zinc ore bodies are all produced in the tectonic fracture zone and are controlled by the fault structure. The ore body is mainly distributed in the fragmented Ying'an rock of the second member of the Upper Ordovician Latquanquan Group. The altered mineralization has silicification and kaolin. In addition, the ore-bearing rock is a fragmented Yingan rock, and the ore structure is powdery or gelatinous, and has a film-like shape and a fine vein shape.
