摘　　要：在分析沙那黑地区区域地质资料的基础上,通过地质草测、土壤剖面、激电剖面、激电测深、槽探工程等方法分析了该地区地质特征、化学元素组合特征、电物性特征、激电异常特征及激电测深特征。研究表明:沙那黑地区具有较好找矿前景的矿种为铅、锌、银,成因类型以构造蚀变岩型为主,兼顾热液型。其有利成矿部位为构造蚀变带内的黄褐色绢云石英片岩中,研究区发现的矿(化)体多产于此。Based on the analysis of regional geological data in Shanahei area,the geological characteristics,chemical element combination characteristics,electrophysical characteristics,IP anomaly characteristics and IP sounding characteristics of the area are analyzed by means of geological grass survey,soil profile,IP profile,IP sounding engineering and other methods.The results show that lead,zinc and silver minerals with good prospecting prospect in Shanahei area are mainly tectonically altered rock type and hydrothermal type.The favorable ore-forming location is the yellowish-brown sericite-quartz schist in the tectonic alteration zone,where most of the mineralized bodies found in the study area are produced.
