Abstract

The telluric field and apparent resistivity anomalies caused by an inclined normal fault are calculated along a profile perpendicular to the strike of the fault. The method of conformai mapping is used to obtain an analytic solution of the boundary value problem. Numerical results are presented in the form of a series of graphs. It is concluded that the angle of inclination for a basement fault can be determined quantitatively for a large throw or qualitatively for a moderate throw.The effect of anisotropic strata on the anomaly curves is discussed.
