Detectability of Electrical Anisotropy Using Marine MT

Z-99 Detectability of electrical anisotropy using marine MT H015 Abstract 1 Changchun Yin 2270 Argentia Road Unit 2 Mississauga Ontario L5N 6A6 Canada A layered isotropic half-space model is for many cases a good approximation to geophysical reality. In regions with distinct dipping stratifications however it is difficult to model the electrical fine structures so that the replacement of this isotropic conductor with electrical preferential direction by a uniform macro-scale anisotropy might be justified to a first approximation. To formulate the forward magnetotelluric (MT) problem for a layered earth with arbitrary anisotropy I assign to each layer of the earth
