Mineral Exploration

Mineral Exploration India has vast resource of mineral and satellite remote sensing is essentially used in regional survey to narrow down potential belts of mineralization's. Some of the guides for mineralization especially geological, geomorphological and structural can be deciphered from satellite data for narrowing zones for detail explorations. Remote sensing has significant role in geoexploration studies. Geoexploration studies include mapping of lithounits known for hosting mineral deposit, mapping of structural controls of mineralization and mapping of surface signatures( i.e. alteration minerals like gossans, phyllic, argillic zones with different assemblages of clay minerals associated with hydrothermal deposit) associated with mineralization. High to moderate spatial resolution data are used to often controls the emplacement of economic rock like kimberlite.Hyperspectral data collected in laboratory environment can be upscaled to bandwidth of hyperspectral or advanced multispectral data for mapping surface mineralogy of proxies of mineralization.

Bauxite mapping in parts of Jharkhand.

SpectroscopicIn recent times, laboratory spectra of different economic rocks are analyzed to identify diagnostic absorption feature imprinted in the reflectance spectra of respective economic rocks. Further, these diagnostic spectral features are upscaled to the bandwidth of advanced multispectral data of space borne sensors for spatial mapping of different economic rocks.
