Olivine is a major basaltic mineral in hightemperature volcanic rocks and in stony meteorites. The D’Orbigny angrite contains large olivine crystals (up to ~ 1 cm in size) that are present throughout the rock, mimicking xenocrysts or forming olivinite (polycrystalline olivine) [1-3]. The olivinites are of particular interest, as very little is known about them. Here, we study three types of D’Orbigny olivines: honey olivine (HOl), green olivine (GOl), and olivinite (POl), by Raman, Fouriertransform infrared (FTIR), and Mössbauer spectroscopy, and compare their structural and spectral features
