Crust morphology, mineralogical composition and structure are studied. Optical data are established by microscopical analysis of eight thin sections and two polished surfaces. Compared with electron‐probe analysis, they are found in good agreement. Bur‐Gheluai is an holocrystalline, olivine‐bronzite chondrite, with evident features of recrystal‐lization and met
