Scientific paper

Visible and near-infrared reflectance spectra of martian meteorites (shergottites, nakhlites and chassignites) have very prominent absorption bands in the visible and near-infrared controlled by their mineral composition and texture. However, the surface of Mars is mostly covered with dust with optical properties controlled by Fe3+ absorption in the visible and ultraviolet. The range of diagnostic aborption band parameters is investigated with Modified Gaussian Method analysis. We present mixing models of SNC meteorites with martian bright and dark region spectra to explore the ability to extract diagnostic spectral features of SNC meteorites from surface reflectance and color relationships of areas on Mars.
