Abstract
In the present paper is studied the influence of transverse ground anisotropy on the formation of self-potential (SP) anomalies produced by polarized bodies. It is concluded that SP anomalies produced by vertical dipoles of infinite length are displaced in the opposite direction of the dip angle of anisotropy. The equipotential lines are generally ellipses. SP anomalies produced by a vertical dipole of finite length are also displaced, have a negative and a positive centre and present the characteristics of an SP field produced by an inclined dipole in a homogeneous and isotropic ground. In both models, significant errors in the quantitative interpretation of SP anomalies may result from not taking ground anisotropy into account.
