摘要
激电中梯测量是在矿产勘查工作中应用广泛、找矿效果良好的一种地球物理勘探方法。而石墨矿相对于围岩的物性特征主要体现为低阻和高极化,依据这一独特的物性条件,在西峡县尹家沟石墨矿普查工作中采用激电中梯测量的物探测量方法,结合地质和槽探对石墨矿体的揭露情况布设激电测深工作,进行电阻率和充电率异常提取及资料解译,通过后期钻孔验证,取得了良好的找矿成果,表明采用激电中梯测量方法对寻找石墨矿具有较好的指示意义。
IP mid-gradient survey is a geophysical exploration method which is widely used in mineral exploration.It has good prospecting results.The physical characteristics of graphite ore relative to the surrounding rock are mainly reflected in low resistivity and high polarizability.Based on this unique physical condition,IP mid-gradient survey method was used in the survey of Yinjiagou graphite deposit in Xixia County.Combining the exposure of graphite ore bodies by geology and prospecting trench,IP sounding was deployed.The abnormal extraction of resistivity and charging rate and data interpretation were carried out.Through later drilling verification,the good prospecting results have been obtained,which shows that the IP mid-gradient survey method has a good indication significance for the exploration of graphite ore.
