Abstract

Near-infrared reflectance spectra of the Martian surface taken from the imaging spectrometer ISM have been analyzed to study the composition of the surface. The most prominent spectral criteria related to the surface are found to be variations of infrared brightness, of continuums slope, of absorption features between 2.2 and 2.5 micrometers , of a band of bound water at 3 micrometers and of the complex ferric-ferrous absorption near 1 micrometers . Spectral maps created from the ISM data allow us to discuss variations of composition and surface morphology.
