Reflectance spectra of heated carbonaceous chondrites

Abstract

We aim to understand the spectral characteristics of carbonaceous chondrites (CCs) heated on their parent bodies. Weakly heated CCs show positive spectral slope, the 0.7-μm band, and sharp 3-μm band. Strongly heated CCs show decreased slope and shallowed and rounded 3-μm band, and no 0.7-μm band. Serpentine dehydration and secondary anhydrous mineral formation could be the cause of spectral changes.
