摘要
通过在青海省茫崖市牛鼻子梁地区开展激电中梯测量,本文在综合分析以往资料的基础上,利用1:5000激电剖面确定铜镍成矿有利地段,并进行钻探验证。进一步认识该矿区各类岩(矿)石的电性特征及分布情况,了解测区内激电异常在平面的分布规律及展布情况。经过成果资料整理及分析,结合激电异常分析研究,工区内共圈定出JDⅠ、JDⅡ两条激电异常带,JDⅠ异常带规模较大,东西长度约为600m,南北长度约600m。JDⅡ异常规模较小,异常长度约为400m,宽度约为100m。大致查明了工区内激电异常分布特征为:北部的极化率较低,南部的极化率相对较高,工区西南部的激电异常优于工区东部的激电异常。
Based on the comprehensive analysis of previous data,a 1:5000 IP profile was used to determine favorable areas for copper and nickel mineralization by conducting IP ladder measurements in the Niubiliang area of Mangya City,Qinghai Province,and drilling verification was conducted.Further understand the electrical characteristics and distribution of various rocks(minerals)in the mining area,and understand the planar distribution and distribution of induced polarization anomalies in the survey area.After organizing and analyzing the results and data,combined with the analysis and research of induced polarization anomalies,two induced polarization anomaly zones,JD I and JD II,have been delineated in the work area.The JD I anomaly zone has a larger scale,with an east-west length of about 600m and a north-south length of about 600m.The JD II anomaly has a relatively small scale,with a length of approximately 400m and a width of approximately 100m.The distribution characteristics of induced polarization anomalies in the work area have been roughly identified as follows:the polarization rate in the north is relatively low,while the polarization rate in the south is relatively high.The induced polarization anomalies in the southwest of the work area are better than those in the east of the work area.
