ANALYSIS OF THE DEFORMATION OF HOMOGENEOUS ELECTRICAL FIELDS OVER SOME 2-DIMENSIONAL STRUCTURES

An analysis of the deformation of a homogeneous electrical field cause d by a long, thin inclined bed, which is of considerable importance in the exploration of ground water and minerals, is presented using the Hilbert transform. The thickness of the bed and the inclination are ex pressed as a function of the abscissae of the points of intersection o f the horizontal and vertical derivatives of the field. The procedure is illustrated with a theoretical example and substantiated with field examples from the fractured Crystalline Basement Complex in Burkina F aso, Africa, and Pre-Cambrian limestones of the Cuddappah Basin in And hra Pradesh, India. The results derived from the analytical method are shown to agree well with the ground truth.
