Petrography: The meteorite displays a grayish to slightly greenish interior and is a carbonaceous chondrite composed of large chondrules (up to 3 mm sized), whitish CAIs (up to 4 mm sized), and olivine amoeboids all set into a fine-grained grayish matrix. Opaque phases are Ni-rich sulfides, trolite, and rare metal.
