Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules and chondrule fragments, up to 1.8 mm across, in a black matrix containing small amounts of nickel-iron and troilite. The chondrules are mainly granular and porphritic olivine and olivine-pyroxene, with a few radiating and cryptocrystalline pyroxene. Microprobe analyses show olivine and pyroxene of variable composition; olivine, Fa1-32, mean Fa14; pyroxene, Fs4-18. The meteorite is classified as an L3 chondrite (estimated L3.4).
