High resolution aeromagnetic data collected over northwest Botswana has provided new insights into previously hidden geologic structures. Major antiformal and synformal structures have been recognized within the Kinabaran age Kgwebe meta-volcanics and other basement rocks. These structural features trend northeast-southwest agreeing with previously collected geologic field data and observed surface features. Further interpretation of the geophysical data has yielded relative dips of the fold limbs and indication of the direction of plunge. Folding extends both north and south of the Okavango Rift Zone for at least 100 - 200 kilometers. Further studies are being conducted to determine if these pre-existing geologic features exert structural control on neotectonic activity.
