Abstract

In order to identify potential zones for clay mineral (kaolinite) in Ranong province, Thailand, ten 2D ERT survey lines were deployed across potential site. The data were collected using the IRIS Syscal Pro Plus multi-electrode imaging system with internal switchbox and an array of 48 steel electrodes. The Dipole-Dipole configuration was utilized with electrode separations of 10 m. The Res2DInv software was used to process the data. Images for the resistivity survey are presented as 2D cross section of resistivity profile. The data were interpreted by comparing with geology of the area and based on the available lithological borehole information.
