Abstract

A geoelectric image of a portion of the Sao Fransisco sedimentary basin (Minas Gerais) was obtained based on magnetotelluric (MT) data from 43 MT soundings (400 Hz - 0.001 Hz). The soundings were carried out along 10 seismic lines. covering an area of 11.000 km˛ approximately. The distances between soundings were irregular and varied from 2.5 km to 20 km. Static shift corrections were applied to the data using the median resistivity of the first conductor. One dimensional (1D) Occam geoelectrical sections were obtained for all profiles. A sequence of conductors and resistors was found in the sedimentary package. followed by a geoelectrical basement. The MT sections show good agreement with both borehole information and seismic sections.
