Processing and interpretation of an airborne gamma-ray and aeromagnetic survey, combined with Thematic Mapper imagery, enabled the successful discrimination of lithological units and their geological and structural interpretation in a complex area where weathering and a dense vegetation cover make traditional mapping extremely difficult. The visual inspection of-RGB color composites reveals the differentiation of the area into distinct color domains, each of which has been related to existing geologic units. The aeromagnetic data not only reveal superficial structures, but also show deeper structural detail inside the tectonometamorphic complexes of the area, adding weight to existing hypotheses on the evolution of the Kibaran orogeny.
