Physical Description: Roberta Score All except one surface is covered with a thin brown and black colored fusion crust. That one surface is a planar weathered fracture surface that ranges in color from yellow to reddish brown. Chipping revealed an interior with a small (1 mm) weathering rind. Chondrules are obvious in the unweathered (50% of the stone) interior material. Dimensions: 3.5 x 2 x 1 cm.
Petrographic Description: Brian Mason Chondritic structure is moderately well-developed, chondrules ranging up to 1.8 mm across. The groundmass between the chondrules is fine-grained olivine and pyroxene, with minor amounts of nickel-iron and troilite. Some limonitic staining is present, concentrated around the nickel-iron grains. Microprobe analyses gave the following mineral compositions: olivine, Fa18; pyroxene, Fs16.
