【摘要】 在鄂西震旦系白云岩地层中,新发现了白鸡河锌矿床、凹子岗铅锌矿床、冰洞山铅锌矿床。白鸡河锌矿床矿石成分简单,富锌贫铅;矿石结构主要为细晶结构、交代结构;矿石构造变化大,存在角砾状、浸染状、纹层状、条带状及"雪顶"构造;成矿温度低,白云石化交代角砾岩作用普遍;矿石硫同位素为重硫,值域很宽,闪锌矿与方铅矿在相对封闭环境沉淀。矿床地质特征可与MVT型铅锌矿床相类比,成因为碳酸盐岩容矿的后生沉积铅锌矿床。更多还原

【Abstract】 In West Hubei,some new found ore deposits such as Baiji river zinc deposit,Aozigang lead-zinc deposit and Bingdongshan lead-zinc deposit have been discovered in dolomitite of Sinian stratum,which components are simple,including rich zinc and deficient lead;Ore structure mainly includes the fine-grained structure and metasomatic texture structure;Ore constitution,which consists of brecciated structure,impregnation structure,laminated structure,streaky structure and "snow top " structure,changes obviously;The mineralization temperature is low and the dolomitization replaces breccia extensively;Sulfur isotope is heavy sulfur and the range is very broad,the exchange of Sulfur isotope between galenite and blende keeps balance,the blende and galena deposit in an closed relatively environment.The mineral deposit geological character can analogy with MVT type lead zinc deposit and its style is contained-carbonatite epigenetic deposition lead zinc deposit更多还原
