2D Resistivity Imaging of an Anisotropic 3D Body – Results of a Laboratory Experiment

A simplified 3D model of a vertically “fissured” underground object was studied with 2D resistivity imaging at laboratory scale. The model was built with insulator sheets forming a parallelepiped “cake” embedded in a homogeneous medium (water). Both apparent resistivity of cross-sections and inverted models are complex and depend on the direction of the measuring line in relation to the “fissures”.
