Macroscopic Description: Kathleen McBride
The exterior of these achondrites has very small patches of black fusion crust. Areas without fusion crust expose an interior that is gray-green in color with yellow-rust colored patches and haloes. The interiors are fine-grained, yellow ochre in color with rust stained, white or gray inclusions and chondrules/chondrule-like spheres. 082 has areas that are black in color.

Thin Section (, 2) Description: Tim McCoy
These meteorites are very similar and tentatively paired. The sections show a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with basaltic and orthopyroxenite clasts ranging up to a few mm. Pyroxene includes orthopyroxene of Fs21Wo2 and finely-exsolved (1-3 µm) orthopyroxene/augite intergrowths of Fs57Wo2 and Fs24Wo40, respectively. A single olivine grain in MET 01087 is Fa26; plagioclase is An85-90Or0.5 and a single SiO2 grain was analyzed. The meteorites are howardites and, on the basis of similarity in find site with MET 01082 and 01087 and petrographic features, may be paired with MET 96500.
