The southern part of the Senegalo-Mauritanian basin is geologically featureless, and little is known about the division of the sedimentary sequence and regional geological structure because of the scarcity of deep drillholes. A magnetotelluric survey was, therefore, carried out in an attempt to obtain details concerning the electrical characteristics, thickness and structure of the Mesozoic-Cainozoic Senegalo-Mauritanian basin. From the surface down, the interpretation of magnetotelluric data shows several distinct electrical boundaries. The general trend shows a decrease in near-surface resistivity from east to west. The basin is characterized by water-saturated, unconsolidated, low-resistivity sediments, with a westward-sloping monoclinal style. |
