Abstract

Data from part of the Southern African Magnetotelluric Experiment (SAMTEX) have been analysed using an<br>impedance tensor decomposition method in order to gain a better understanding of geoelectric directionality and<br>dimensionality and its variation with depth, and the electrical anisotropy properties of the region. The SW-NE transect<br>from Sutherland to Messina, South Africa, is coincident with part of the Kaapvaal Craton Project’s Southern Africa<br>Seismic Experiment (SASE) deployment. Shear-wave splitting analyses on the SASE data, reported in the literature,<br>showed that splitting delay times appear to exhibit geological control, with the Late-Archean regions showing generally<br>greater anisotropy.
