Prospecting for hydrothermal mineral deposits in the Himalaya using short-wave infrared spectroscopy

Hydrothermal alteration minerals associated with the hydrothermal ore deposits were identified using hyperspectral remote sensing. Hyperion data were also used for regolith mapping using object oriented image classification method and found suitable when verified in field. Spectroscopic analysis of the field samples and there mixture analysis revealed clay minerals like illite and montmorillonite along with the goethite, dolomite, epidote, clinochlore, muscovite and hornblende. Though the SNR of the hyperion data was very low but still it gives good indication of the altered minerals in the Kumaon Himalaya, India.
