Composition and classification

This meteorite is intermediate between L and LL ordinary chondrites, possibly indicating formation on a separate parent body. ^[3] Its fayalite, ferrosilite place this stone at the extreme higher end of L chondrites, the metal content is typical of LL chondrites and the Co abundance in matrix kamacite (15 mg/g) is at the extreme lower end of LL chondrites.
