Use of aerospace data for uranium exploration in parts of Southern Bastar, Central India

International Journal of Remote Sensing (1993)

Amit Chawla S.N. Kak Ravi Kaul

Abstract 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.

Discrete Selenide Phases from the Uraniferous Mahadek Sandstones of Domiasiat and Wahkyn South, West Khasi Hills District, Meghalaya

Journal of Geological Society of India (2002)

E.V.S.S.K. Babu S. Nayak Alok Kumar P. Krishnamurthy S.N. Kak

Occurrences of discrete selenide phases in the geological environment are rather rare and are confined to a few sulphide deposits and sandstone-type uranium deposits such as those of the Colorado plateau, USA. The occurrence of discrete selenide phases viz., clausthalite (PbSe), ferroselite (FeSe 2 ) and Co-penroseite (CoNiCuSe 2 ) are reported for the first time from the Uraniferous Mahadek sandstones of Domiasiat and Wahkyn South, West Khasi Hills District, Meghalaya. The selenide phases are associated with pyritiferous organic matter, pitchblende and other ore minerals such as marcasite and sphalerite.

Application of remote sensing techniques for nuclear power project site selection in India

International Journal of Remote Sensing (1993)

V.J. Katti Y. R. SATYA SARADHI S.N. Kak Deepanwita Banerjee Ravi Kaul

Abstract A successful engineering project has to be meticulously planned so that it causes least disturbance to the natural environment around the project. This consideration becomes very critical during selection of a site for locating a Nuclear Power Project. The task warrants the involvement of a number of experts from several disciplines, like civil engineering, geology, seismology, health-physics and others. Most of the real-time reliable thematic information for the project can be generated by scale-elastic aerospace remote sensing data. This data is to be supplemented with the available data-base covering geology, geomorphology, seismotectonics, ground water, population centres, rail-road network, other strategic installations, forest-mineral resource information and others. Systematic evaluation of these data-base aids regional analysis and screening of the potential and candidate sites, thus leading to the final selection of the preferred candidate site as well as arriving at safety related aspects of the detailed stage of design and construction. This article is an attempt to provide an insight into the applicability of remote sensing in site selection procedures. Application of these techniques to seismotec-tonic aspects around the Kakrapar Atomic Power Project (KAPP) site in Gujarat are dealt with in detail.
