内蒙古自治区甘东七运锌矿成矿地质特征和找矿潜力评价

Metallogenic Characteristics and Prospecting Potentiality Evaluation of Gandong Qiyun Zinc Mine in the Nei Monggol Autonomous Region

甘东七运锌矿位于内蒙古自治区阿里河地区,矿区地层主体为新元古界震旦系倭勒根群大网子组(Zd),矿区内岩浆岩中以燕山晚期岩浆活动最为活跃,主要是中酸性侵入体。矿区共发现6条工业矿体,呈北西向赋存在大网子组变质砂岩构造破碎带内,矿体主要受控矿断裂控制。经判断此矿床成因类型为充填—交代热液型铅锌矿床。本区找矿远景及资源潜力较大,有进一步向大型发展的可能。

Gandong Qiyun zinc deposit is located in Ali river area in Inner Mongolia. Its main strata is neoproterozoic erathem Sinian system,Wolegen group, Dawangzi subgroup. The magmatic rocks are in late yanshanian magmatic activity, mainly for the acidic intrusive body. Six industrial orebodies were found in the mining area, and the ore body was controlled by fracture structure in the fracture zone of the metamorphic sandstone structure. The genetic type of the deposit is determined as the filling-metasomatic type lead and zinc deposit. There is a great potential for ore prospecting and resource potential in this area.
