Petrography: (A. Tomkins, Monash) Chondrule edges are indistinct, matrix and chondrule mesostases are strongly recrystallised, and plagioclase grains are up to 50 µm across, but mostly less than 20 µm. Discernible chondrule varieties include RP, BO, PO, PP, POP. Olivine has sharp optical extinction, there are irregular fractures and no melt pockets. About 20% of the metal has been destroyed by rusting, whereas most troilite remains.
