2-D SubsurfacelmagingTechniques for DeepOre MineralMappingUsing Geoelectrical and InducedPolarization (IP) Methods

摘要

The 2-D DC resistivityand Induced Polarization (IP) methods aresuperiorfor ore mineral exploration due to simplicity of data acquisition and interpretation..Thesemethods areeffective to detect shallow ore mineral distribution (~100 m). However, for targeting adeep ore mineral distribution, these methods are still encountered bysome problemsespecially in data acquisition at the field scale. To solve these problems, we proposed a method to find the most effective and efficient techniques to obtain a 2-D resistivity and IP of subsurface imaging up to 400 m depth. The proposed method is an application ofVertical Electrical Soundin (VES) using Schlumberger electrode configuration witha short spatial lag. TheVES method was usedto obtain 1-D resistivity modelin general. This paper presenteda VES application to a 2-D DC resistivity and IPmethodsusing awell-known RES2DINV software. The result of our proposed technique usingsynthetic datais reasonable to be applied for the real data.
