Physical Description: Roberta Score

Fusion crust covers two surfaces of this weathered stone. One fracture surface has slickenslides visible on it. Chipping exposed an area of - 1 cm of medium to dark gray colored material and a large weathering rind. Dimensions: 2 x 1.5 x 1.5 cm

 

Petrographic Description: Brian Mason

Chondritic structure is moderately well developed, with chondrules up to 1.3 mm in diameter. They are set in a granular groundmass of olivine and pyroxene, with minor amounts of nickel-iron and troilite and a little plagioclase. Brown limonitic staining is present around the metal grains. Microprobe analyses give the following compositions: olivine, Fa19; pyroxene, Fs16; plagioclase, An12; accessory merrillite was identified. The meteorite is classified as an H5 chondrite.
