Multi-platform and multi-spectral remote sensing techniques have been widely used for geological evaluation of very large terrains. Availability of additional information such as high sensitivity Airborne Gamma-Ray Spectro-metric (AGRS), and other geophysical and geological data enable one to narrow down favourable target areas for detailed ground follow-up for uranium exploration. Late Proterozoic, intra-cratonic areas in the Indravati basin and adjoining areas of supra-crustals and basement crystalline rocks in Southern Bastar, Central India have been evaluated to determine whether a correlation exists between above average uranium enrichment zones and geological settings, in order to select areas for ground radiometric surveys. These studies have aided precise delineation of the litho-boundaries and structural trends. Of the six major lineament trends identified, NW-SE and NNE-SSW trends appear to have been the most favourable for bringing labile uranium into the system. The present location of uraniferous zones seem to have been influenced by the NE-SW and WNW-ESE trends reactivated during acidic instrusive activity and the selective removal of uranium from highly deformed areas has been concentrated along these same trends. These studies have helped to reduce the target for further investigations to 3 per cent of the total area (30000 km2) studied. |
