Thin Section (, 2) Description: Tim McCoy
These two meteorites, found within 1 km of each other, are so similar that a single description suffices. The sections exhibit numerous large, well-defined chondrules (up to 3 mm) in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Olivines range from Fa_10-31; pyroxenes from Fs_3-22. The meteorites are L3 chondrites (estimated subtype 3.6).

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.

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 An_85-90Or_0.5 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.
