The Modified Gaussian Model (MGM) is argued to be a powerful tool for analyzing mixture spectra of asteroids if additional physically based constraints are applied to the modeling. Using constraints based on the range of observed variations in absorptions in olivine across its solid solution series makes it possible to analyze and estimate the chemical composition of the olivine-rich asteroid 246 Asporina. The GM is successfully applied to quantify compositional variations of olivine spectra and pyroxene mixture spectra, providing a solid basis for interpretation of unknown spectra.
