Abstract

In order to develop the subsurface exploration method by means of the three-dimensional electromagnetic method, we adopted the QL inversion method, which is based on the quasi-linear approximation of the integral equation method. The QL inversion method determines the anomalous resistivity of the volume elements, into which the inversion region set up in the layered earth is divided. From the 3D volume data, which is obtained by the 3D inversion, subsurface distribution of the anomalous resistivity bodies is visualized using the 3D visualization softwares. As corresponding to the block representation in the case of 2D cross-section, we report an example of the brick-representation in the case of 3D problems.
