| 摘 要： | 纳雍枝铅锌矿床位于五指山背斜北东部,是五指山矿集区的组成部分.区内铅锌矿体产于清虚洞组的白云岩中,自下而上共划分为9个矿体层,属沉积型铅锌矿床.矿石类型为碳酸盐岩型铅锌矿石.五指山地区位于紫云-垭都深大断裂的北东侧,南东侧有安顺-凯里深断裂,这些深断裂是纳雍枝矿床深部物质来源的前提,次一级的构造为矿床的形成提供了矿质流动的通道.五指山背斜Pb、Zn综合异常明显的部位,异常与区内构造较吻合,与矿床(点)展布方向一致.该矿床与典型密西西比河谷铅锌矿床具有较高的可比性.通过对纳雍枝铅锌矿床地质特征的总结及分析,认为五指山地区的找矿前景十分广阔.

| Abstract: | The Nayongzhi Pb-Zn deposit,situated in the northeast of Wuzhishan anticline,is a component of the Wuzhishan ore-concentrating zone.The orebodies occur in the dolostone of Cambrian Qingxudong formation,consisting of nine ore layers.The ores belong to carbonate rock type.The Ziyun-Yadu deep fault in the southwest and Anshun-Kaili deep fault in the southeast of the region are the prerequisites for the material source of the deposit.The secondary structures provide flow channels for ore fluid.The comprehensive Pb-Zn anomalies coincide to the regional structures,as well as the distribution of ore deposits （occurrences）.The Nayongzhi Pb-Zn deposit is much comparable to the Mississippi Valley Pb-Zn deposit.The geological characteristics of Nayongzhi Pb-Zn deposit show a great prospect of exploration in Wuzhishan region. |
