摘要
纳雍枝铅锌矿床是近年来贵州省境内发现的一大型铅锌矿床,是川滇黔铅锌成矿域的一个组成部分,地处黔中隆起南侧,于五指山背斜核部发育。矿区内矿体旁侧及近矿围岩均有不同程度的白云岩化,通过宏观地质编录,及镜下光薄片微观特征的观察,系统地对蚀变白云石的类型进行了分类,对蚀变白云石的形成环境,物质来源以及形成机制进行了探讨。
The Nayongzhi lead-zinc deposit is a large lead zinc deposit discovered in Guizhou province in recent years.It is a part of the metallogenic domain of the lead zinc deposit in Sichuan Yunnan and Guizhou.It is located on the south side of the central Guizhou uplift and the development of the core of Wuzhishan anticline.Mining orebody lateral and ore country rocks have different degrees of dolomitization in macro geological logging and mirror observation of polished thin section microscopic characteristics.Dolomite types are classified,as is discussed in the alteration of dolomite formation environment,material sources and the formation mechanism.
