چکیده

The mafic and ultramafic rocks of Mettupalayam belong to the southern granulite terrain India, which is concomitant with vital economic resources. advantage Advanced Spaceborne Thermal Emission Reflectance Radiometer (ASTER) data for mapping litho units are exploited well here differentiating rock aid band combination (1, 3, 6), principal component analysis (5, 1, 6) ratioed (2/3, 3/2, 1/5 (9–8)/1, (8–6)/2, (9–6)/3). As part field study, collection samples ground control points were carried out in addition that, generation laboratory reflectance spectra was achieved. Spectral Angle Mapper (SAM) Support Vector Machine (SVM) performed using ASTER obtained from conditions demarcate abundance area. XRF method used retrieve major oxides field-collected spectral absorption characters validated it. results show a vibrant interpretation units.
