India is well enriched with bauxite deposits. Bauxite deposits of Shevaroy hills in Salem district, Tamil Nadu are derived from laterites by lateritization process. Bauxite, the chief source of Alumina, is an aggregate of minerals most of which are oxide and hydroxide of aluminum and iron rich like gibbsite, boehmite, goethite and hematite. Bauxite is used in the refractory industries and its quality is controlled by presence of impurities such as iron and silica. In the study area bauxite is a whitish red to brown aluminum ore mineral mainly made up of hydrous aluminum oxides and aluminum hydroxides and laterites are mostly found in humid tropic climatic condition due to intense weathering of bed rock. To delineate bauxite deposits from the associated laterites ASTER satellites (Advanced Space Borne Thermal Emission Radiometer) image is processed. For this, bauxite's spectral signatures and aluminous laterite samples were analyzed in the lab with respect to gibbsite (mineral constituent of bauxite) and goethite (mineral constituent of laterite) in VNIR-SWIR (Very near Infrared and Short Wave Infrared) region. For spectral discrimination of minerals, ASTER data acquired in the VNIR - SWIR regions were used. To understand the different chemical composition of bauxites there is difference in absorption peak of spectra while analyzing the spectral signature of lateritic bauxite samples from the lateritic spectral data generated from the instrument Analytical Spectral Devices (ASD- Field spec 3) which operates in spectral region of 0.35 - 2.5μm (350 - 2500 nm) with 10 nm band width was used. The Bauxite sample has a strong absorption peak in the spectral regions of 2.26&
