Petrographic Description: Brian Mason

Chondrules are abundant and well-developed, ranging up to 1.5 mm in diameter; a variety of types are present, the commonest being granular and porphyritic olivine and olivine-pyroxene (much of the pyroxene is polysynthetically twinned clinobronzite). The chondrules are set in a ground-mass consisting largely of fine-grained olivine and pyroxene, with minor amounts of coarser-grained nickel-iron and troilite. A moderate degree of weathering is indicated by brown limonitic staining concentrated around metal grains. Microprobe analyses give the following compositions: olivine, Fa24; pyroxene, Fs20. The meteorite is an L4 chondrite.
