Abstract

Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade, with advancement in laboratory spectral calibrations and validation of interpretive methodologies by spacecraft rendezvous missions. This has enabled the accurate identification of several meteorite parent bodies in the main asteroid belt and helped constrain the mineral chemistries and abundances in ordinary chondrites and basaltic achondrites. With better quantification of spectral effects due to temperature, phase angle, and grain size, systematic discrepancies due to noncompositional factors can now be virtually eliminated for mafic silicate-bearing asteroids. Interpretation of spectrally featureless asteroids remains a challenge. This chapter presents a review of all mineralogical interpretive tools currently in use and outlines procedures for their application.
