Petrographic Description: Brian Mason

Chondrules are abundant, ranging from 0.3 to 1.5 mm in diameter; a wide variety is present, the commonest being granular olivine and olivine-pyroxene, and fine-grained pyroxene. The granular chondrules have intergranular glass, sometimes pale brown and transparent, but commonly turbid and partly devitrified. Irregular granular clasts and chondrule fragments are also present. Most of the pyroxene is polysynthetically twinned. The matrix consists of fine-grained olivine and pyroxene, with minor subequal amounts of nickel-iron and troilite. Veinlets of limonite and brown limonitic staining pervade the section. Microprobe analyses show olivine ranging in composition from Fa15 to Fa29, with a mean of Fa20; pyroxene ranging from Fs6 to Fs28, with a mean of Fs13. This range of composition, together with the presence of glass, indicates type 3, and the low content of nickel-iron suggests L group; the meteorite is therefore tentatively classified as an L3 chondrite.
