内蒙古哈达特陶勒盖银铅锌矿矿床地质特征

摘要

Hardat Tolgoi Ag - Pb - Zn Deposit is located in the northern Abag Qi, inner Mongolia, south of Sino - Mongolia border, occurred in the Erenhot - Dong Ujraqin Qi polymetallic ore belt subordinate to the giant Central Asian ore belt,hosted in the Devonian and Permian strata,controlled by lite clustered NWW trending secondary fraclrures cut through or cutting through by NE sinking faults. Well continuous lodes occur as lenses in the plan,while as sheets,columns,veins,lenses and irregular shape in the space,lades are concealed and half - concealed with shallow depths. The deposit is of altered fractured zone hydrothermal filling type.%哈达特陶勒盖银铅锌矿区位于内蒙古阿巴嘎旗北部中蒙交界处中国境内,属中亚巨型多金属成矿带之二连—东乌多金属带,矿体主要赋存于中酸性岩体(脉)附近的泥盆系、二叠系地层中,严格受成群(组)出现的北西西向次级断裂控制；矿体连续性较好,平面上呈连续—半连续的透镜状,空间上以不规则脉状为主,同时伴有似板状、柱状、透镜状、扁豆状；矿体多为隐伏状—半隐伏状,埋深较大,产状较陡；矿床属中低温破碎蚀变岩热液脉状充填型矿床.
