Application of Remote Sensing for delineation of Uranium bearing Vempalli dolomites in and around Tummalapalli area, Cuddapah Basin, India

The Uanium mineralization within the Vempalli dolomites of Cuddapah Super group in Mabbuchintalapalli, , Tummalapalli area falling in the Survey of India Toposheet No. 57 J/7. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is taken as reference for the Interpretation studies. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is taken as reference for the Interpretation studies. The associations of alteration processes throughout and near the mineralized sectors appear to play an important role in the distribution and localization of the mineralization. The aim of this study was to assess the effectiveness of LISS III data for detecting alteration zones as well as Uranium mineralization in parts of Cuddapah basin. Image processing techniques were applied on the digital subset LISS III data covered studied areas. These techniques generated several products of enhanced satellite imagery such as ratio images, principal component analysis and edge enhancement techniques which have been successfully used in the lithological discrimination of alteration zones and uranium bearing dolomites, structure, geomorphology, alteration zones etc., of the study area. Extensive field geologic studies in the pronounced zones delineated by the image lead to the identification of mineralized locations.
