摘要
运用三维VIP激电观测系统,建立研究区三维空间的电阻率和充电率的反演图,将该方法和结果同可控源音频大地电磁测深、频率域三极激电测深、时间域直流三极激电测深等方法和结果进行对比。分析得出三维激电测深具有数据完备,准确性高,能清晰直观反映地下异常体的形态特征等优点;结合地质、钻孔资料,对反演结果做出了地质解释。研究认为,一号充电率异常体可能由侵入岩体或与侵入体的矿化蚀变引起。三维VIP激电观测系统较其他测深方法具有明显优势,能够更加清晰直观地反映出地下信息,月亮山地区激电工作找矿标志应以中-高阻高极化为主,低阻高极化可能为断层破碎带的表现。
By using the 3D VIP induced polarization observation system,the inversion map for 3D spatial resistivity and charge rate are built.Compared the method and results with CSAMT,frequency domain tripolar IP sounding,time domain DC tripolar IP sounding,it can be conclude that the data of 3D induced polarization sounding is completeness,the results are accurate and the image of the anomalous is clear.Combining geology and drilling data,the geology interpretations for the inversion results are given and the number 1 charge rate anomalous might be caused by intrusive body or the mineralization alternation of intrusive body.The 3D VIP induced polarization observation system has obvious advantages over other sounding methods,which can reflect underground information more clearly and intuitively.The signs of prospecting for IP work in the Yueliang Mountain area should be based on medium-high resistance and high polarization and low resistance and high polarization may be the performance of fault fracture zone.
