摘要
那雍枝铅锌矿床展布于五指山背斜南东翼,受F与F两条区域性断层控制。该矿为中低温热液型铅锌矿,层控矿主要产于清虚硐组(∈q)中下部泥质白云岩、瘤状白云岩与虚脱空间、层间破碎带耦合部位;断控矿主要产于断层破碎带中。两者产状均与围岩或控矿断层基本一致,断控矿比层控矿平均品位高。成矿物质来自变质基底。探讨加强矿山地质工作,重点查明矿体连续性、稳定性,寻找成矿规律;提早谋划深边部找矿工作;加强铅、稀贵金属的探索及综合利用;针对不同矿体采用不同采掘方法。
Nayongzhi lead-zinc deposit is distributed in the southeast wing of Wuzhishan anticline and controlled by two regional faults Fand F.The ore is a medium low temperature hydrothermal type lead-zinc ore.The stratabound ore mainly occurs in the coupling part of argillaceous dolomite,nodular dolomite,void space and interlayer fracture zone in the middle and lower part of Qingxudong formation(∈q);Fault controlled ore mainly occurs in fault fracture zone.Both occurrences are basically consistent with the surrounding rock or ore controlling fault,and the average grade of fault controlled ore is higher than that of layer controlled ore.The ore-forming materials come from metamorphic basement.This paper discusses how to strengthen the geological work of the mine,focusing on finding out the continuity and stability of the ore body and looking for the metallogenic law;Early planning for deep edge prospecting;Strengthen the exploration and comprehensive utilization of lead and rare precious metals;Different mining methods are adopted for different ore bodies.
