Abstract

Interpretation results of refined regional airborne magnetic survey data<br>over southern Namibia are reported. Significant new findings with regard<br>to the regional geology and crustal evolution are:<br>(i) Three major crustal domains have been identified using the magnetic<br>pattern. These are from northeast to southwest the Kalahari craton,<br>the Sinclair and Namaland domains.<br>(ii) The Namaland domain clearly shows indications of intracontinental<br>rifting given by the Karas magnetic trough trending NWISE over a<br>distance of more than 300 1cm.<br>(iii) Three directional magnetic lineament sets are observed in the region:<br>NW/SE, SW/NE and E/W. Magnetic linear features are particularly<br>abundant in the Sinclair domain and the Vioolsdrif sub-domain,<br>which is the southernmost part of the Namaland domain.<br>(iv) Numerous intersections of magnetic linears have been identified and<br>as such are locations with promising potential for hydrothermal<br>mineralization.
