Identification of talc and chlorite mineral in the Askot crystalline of Kumaon Himalaya using hyperion hyperspectral data

In this study an EO-1 Hyperion hyperspectral data has been used to identify the talc and chlorite in the Askot crystallines of the Kumaon Himalaya near to the Ghattabagar village of the Askot town. Identification of the talc was done using the Hyperion data and results were verified by the field and laboratory analysis. Though the SNR of the Hyperion data was very low (10:1) but careful processing of the hyperspectral data has given a very good indication of talc and Chlorite mineral. VNIR and SWIR spectroscopy has been used effectively for identification of VNIR and SWIR active minerals. Mineralogy identified through the Hyperion data stands in good confirmation with the established geology of the area.
