Figure 5

A synthetic cube is shown positioned towards the upper left-hand corner of the 10 × 10 m2 grid (A). The inverted solution also is stretched unto the surface (B). Plotting the interval between 1 Ohm-m to 10 Ohm-m (C), the geometry of the inverted block is depicted distorted and its top outcrops. However, the lateral dimensions and the original resistivity of the block is well recovered.
