Physical Description: Roberta Score

Stone is totally covered with dull brown and black fusion crust. Chipping exposed mostly weathered material. Two inclusions are visible, both are rounded 2 mm in diameter, and gray in color. Dimensions: 2.5 x 1 x 1.5 cm.


Petrographic Description: Brian Mason

Chondritic structure is well developed, with chondrules ranging from 0.3-2.2 mm across. Fusion crust, up to 0.5 mm thick rims most of the section. Brown limonitic staining pervades the section, and is concentrated around the nickel-iron grains and below the fusion crust. Microprobe analyses give the following compositions: olivine, Fa23; pyroxene, Fs20; accessory merrillite was identified with the microprobe. The meteorite is classified as an L5 chondrite.
