# NASA data for ALH 77061 Weathering: B Fracturing: A Pairing: ALH 77021 Fa: 18 mol % Fs: 17 mol %
Approximately one-half of the specimen's surface is covered by a thin, brownish-black fusion crust. The other half of the specimen is a light-to-medium gray, fracture surface with appreciable iron oxide staining. Chondrules appear to be present on fractured surface, however, they are not prominent. This is not a complete stone. From field photographs it is apparent that the B surface was in contact with the ice. Maximum dimension is approximately 2.5 cm.
