Original Classification Diogenite
Macroscopic Description - Cecilia Satterwhite
Dull black fractured fusion crust covers about 70% of the exteriors. Areas without fusion crust are tannish gray. Some white/lighter inclusions visible. 107 has some evaporites on the surface. The interiors are a crème colored/tan matrix with some dark and light clasts/inclusions. A few larger yellowish clasts are visible.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The sections show coarse (up to 5 mm) comminuted pyroxene with minor interstitial plagioclase and SiO2. Pyroxenes exhibit blebby exsolution, with low-Ca pyroxene hosts of compositions Fs29-53Wo1-11 and high-Ca pyroxene exsolution of composition Fs14Wo40.  Fe/Mn ratios of the pyroxenes are ~30.  Feldspars are An82-91Or0.2-0.5.  These meteorites are diogenites, although the pyroxene is on the FeO-rich end of diogenites towards cumulate eucrites.  These are likely paired with MIL 07613.
