Particle size dependency in the diffusion reflective spectrum of L6 chondrite Y75102

Abstract

Space weathering has been invoked to explain the mismatched spectra between asteroid type and meteorite classes. It affects on the reflectance spectra as the darkening and reddening of planetary surface materials and the changes to the depths of absorption bands.
In this study we measured the bidirectional diffused reflectance spectra of L6 chondrite Yamato-75102, from 300nm to 2600nm with the particle size varied. The sample is not so suffered by weathering on terrestrial. We discuss quantitatively the dependence on particle size for the reflectance spectra characterization.
