In addition, the alteration minerals containing ferrous ions show a spectral absorption feature in band SWIR-1 region. Carbonate alteration minerals have a characteristic absorption at the wavelength of 2.30–2.35 μm (band SWIR-8), while relatively high reflectance in the region of band SWIR-6 and SWIR-3.
