Discrimination of iron ore deposits of granulite terrain of Southern Peninsular India using ASTER data

Multi- and hyperspectral geologic remote sensing: A review

“…Analysis of resampled ASTER spectra on magnetite quartzite and associated lithologies of garnet-ferrous pyroxene granulite, hornblende biotite gneiss, amphibolite, dunite, and pegmatite showed absorption features around the ASTER spectral bands 1, 3, 5, and 7. A RGD color composite image of ASTER band ratios ((1 + 3)/2, (3 + 5)/4, (5 + 7)/6) was used to successfully map these sequences (Rajendran et al, 2011). The ASTER SWIR bands allow to some extent the mapping of surface mineralogy (provided that the data are transformed to surface reflectance and provided that mineral occurrences are relatively large so that they can be 'seen' at the spatial footprint of ASTER).…”

Implementation of reflection spectroscopy based new ASTER indices and principal components to delineate chromitite and associated ultramafic–mafic complex in parts of Dharwar Craton, India

“…ASTER data has been utilized in geological mapping for targeting economic rocks like banded iron formation, bauxite, limestone, evaporite etc. in addition to map different alteration zones associated with Pb-Zn, Porphyry Cu, Au deposits (Guha et al, 2013;Rajendran et al, 2012Rajendran et al, , 2011Tangestani et al, 2011). Such wide utilization of ASTER data in geoexploration is possible for its mineralogically sensitive wavelength specification of VNIR, SWIR bands; which were effective in mapping surface alteration zones of hydrothermal deposits, residual enrichment deposits (Guha et al, 2013;Amer et al, 2010;Bedini, 2011;Brandmeier, 2010;Chen et al, 2007;Hosseinjani and Tangestani, 2011;Hashim, 2011, 2012).…”

Recognition of Minerals Using Multispectral Remote Sensing Data: A Case Study in the Sultanate of Oman

“…The technique is widely used in regions which have extremely rugged topography where it is difficult to do dense sampling and detailed conventional geological mapping. Multispectral satellite images acquired by remote sensing play a vital role in mapping of lithological formations and have the capability of providing information on the occurrence and distribution of minerals and rocks [1][2][3][4][5][6][7][8]. Satellite data and image processing techniques are used to map ophiolite sequences, chromite potential zones, hydrothermal mineralized zones, carbonates and carbonatite rocks in the arid region of the Sultanate of Oman [1,[9][10][11][12].…”
