Mineral Exploration

Earth observation data provide valuable inputs for mineral exploration. Space borne earth observation data and their derived image products  provide scope for mapping the host rock and regional structures contributed in localising mineral deposit. Specialised study using hyperspectral and multispectral satellite data provide valuable information on surface distribution of alteration rocks, cap rocks associated with mineral deposit.

High resolution remote sensing (HRS) data are used for mapping geological structures responsible for mineralisation. Geological themes identified using remote sensing data are  integrated with ground geophysical, geochemical data to delineate prospective zone for exploration. Remote sensing studies  were carried out for projects of bauxite, Chromite, diamond, Iron, Manganese, Phosphate etc. A joint study was taken with GSI for demonstrating optimum use of hyperspectral data for identifying  mineralisation targets for detailed exploration. Prospectivity modelling for mineral deposit has been attempted for Bhukia and Zawar area, Rajasthan.
