291 grams. 85 x 50 x 40 mm. Eucrite-pmict AMN writes:Macroscopic Description - Roberta Score Dull black fusion crust covers 80% of LEW86001. Large vugs, typical of all Antarctic eucrites, are abundant. Exterior surfaces without fusion crust have a dirty gray color and show some small inclusions. Some oxidation is present. The interior is lighter gray in color and has areas of heavy oxidation. Numerous clasts some as large as 0.5 cm are present. Thin Section Description (,6) - Brian Mason The section shows a groundmass of comminuted pyroxene and plagioclase (grains up to 0.5 mm), with numerous clasts up to 3 mm across. The clasts consist of pyroxene and plagioclase, with a variety of textures from fine-grained granular to ophitic to gabbroic. A small amount of opaques is present. Microprobe analyses show pyroxene compositions clustered around Wo2Fs56 but ranging to Wo44Fs22, with fairly uniform En content. Plagioclase compositions are An76-88. The meteorite is a eucrite.
