摘要
黔西北纳雍水东—织金五指山地区是川、滇、黔铅锌成矿带的组成部分,其铅锌矿体主要受构造控制,成矿作用与断裂密切相关。典型矿床研究表明,该区铅锌矿体主要产于断裂及角砾状白云岩附近,成矿结构面主要为岩性界面和构造组合结构面,通过对那雍枝铅锌矿和水东洗米沟铅锌矿的研究,建立纳雍—织金一带的成矿模型,认为该区铅锌矿主要受NE向断裂控制,矿体主要赋集于寒武系清虚洞组白云岩及震旦系灯影组白云岩之中,其中灯影组找矿潜力巨大。
Nayongshuidong-Zhijin Wuzhishan area in Guizhouis an important component in the part of Sichuan,Yunnan and Guizhou lead-zinc metallogenic belt.The lead-zinc depositsaremainly controlled by structures.Mineralization and fracture are closely related.The study of typical deposits shows that the lead-zinc deposits in the area are mainly located the nearbyarea of faults and breccia dolomites. The main structural planes are lithologic interfaces and structural combination planes.This paper established the metallogenic model of Nayong-Zhijin area by the study of geological characteristics of lead-zinc deposit in Nayongzhi and Ximigou,Shuidong. The main ore controlling structure is NE faultsand ore bodies mainly enriched in Cambrian Qingxudong formation and dolomite of the Upper Sinian Dengying Formation.The light shadow group has great potential for prospecting.
