| Abstract | Corundum-bearing rocks are associated with metamorphosed mafic rocks in a metamorphic terrain mainly of metasedimentary rocks including gneiss, schist, amphibolite, and minor iron formation. Un oriented corundum crystals surrounded by alkali feldspar halos formed by replacement of the gneiss with the addition of Al and Kin Granulite facies metamorphism of aluminous sediment produced biotite syenite gneiss. Corundum also occurs in cordierite sillimanite schist, gneisses round close pet granite, contact of ultramafics Pegmatite's, Aplite veins disseminated grains in anorthosite kyanite/ staurolite schist, high-grade pelitic schist gravel beds and stream sediments as a placer. It is generally associated with spinel, garnet, kyanite, and high calcium feldspars in plutonic pegmatite and metamorphic rocks. Some of its varieties are oriental amethyst, oriental emerald, oriental topaz, sapphire, ruby (gemstones) and emery (massive). Karnataka state, Dharwar Craton is composed of an active and dynamic geological setting with prospects of many different kinds of economic mineral deposits, including shear zones bearing valuable minerals and gemstones in Precambrian basement rocks. The study area Southern Karnataka covers 20 districts, Field observation using ground truth check, Geochemical analysis data and Hyperspectral data demarcated the Corundum bearing horizons in the study area. Hyperspectral (350-2500nm) is a special type of multispectral imaging scanner which provides a high spectral resolution data to bring out diagnostic features on lithological contacts for better discrimination and rapid demarcated the Corundum bearing rocks across Southern Karnataka. The hyperspectral data on lithological contacts and themes like geomorphology, geology, structure, soil, rocks and minerals will be studied using high-resolution satellite data such as Landsat 8 is a high multispectral imaging radiometer consists of three separate subsystems, Visible near InfraRed (VNIR-15m), Short Wave Infrared (SWIR-30m) and Thermal Infrared (TIR-90m) that have become a potential tool for mapping of precious gemstones in between lithological contacts and mineralized zone. The present study aims to integrate the advent hi-tech tools of hyperspectral Remote Sensing (RS), Geochemical analysis data, EDS analysis data and Geographical Information System (GIS) in demarcating, exploration, scientific surveying of corundum bearing litho units in Precambrian basement rocks of Southern Karnataka. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
