Macroscopic Description: Cecilia Satterwhite

Both specimens are covered with weathered fusion crust. The interior of both fragments is-fed-brown. Light colored chondrules are visible in LEW85437.

Thin Section (LEW85434,5; LEW85437,3) Description: Brian Mason

These sections are very similar, and the same description applies to both; they are probably paired. They show a close-packed aggregate of chondrules and chondrule fragments, up to 1.8 mm across, in a small amount of dark matrix containing a little troilite and nickel-iron. Chondrule types include granular and porphyritic olivine and olivine-pyroxene, barred olivine, and fine-grained radiating pyroxene. Weathering is extensive, with brown limonitic staining pervading the sections. Olivine and pyroxene show a wide range in composition: olivine, Fa1-23, mean Fa10 (CV FeO is 76); pyroxene, Fs2-11. This range of compositions indicates type 3, and the small amount of nickel-iron suggests L group; the meteorite is therefore classed as an L3 chondrite (estimated L3.4).
