内蒙古自治区翁牛特旗姚家店铅锌矿地质特征

Study on Geological Characteristics of Yaojiadian Lead-zinc Deposit in Wengniute Banner of Inner Mongolia Autonomous Region

内蒙古自治区翁牛特旗姚家店铅锌矿矿床为一受NW向断裂带构造控制的中低温岩浆热液充填交代型铅锌矿床,形成于燕山晚期,矿体呈脉状产于二叠世额里图组安山质凝灰岩之构造破碎带内,形态产状严格受断裂构造控制。矿石为硅化、黄铁矿化碎裂岩型铅锌矿石。

Yaojiadian lead - zinc deposit in Wengniute banner of Inner Mongolia Autonomous Region is a medium - low temperature magma hydrothermal filling and metasomatism lead- zinc deposit controlled by fractural composite construction with the trend of NW. It was formed in late Yanshan period, and the ore bodies occurred in fractural belt of andesitic tuff in Permian Erlitu formation with the vein type.
