RARE, Lunar Meteorite! NWA 2977 is a beautiful, Lunar meteorite from the Sahara Desert. It has a total known weight of only 233 grams, and is full of shock melt veins (dark veins seen in photos). It has been classified as a minimally weathered Lunar Olivine Gabbro.

The following description is part of the excerpt on NWA 2977 from Meteoritical Bulletin 90:
Northwest Africa 2977
Find: 2005 November
Achondrite (Lunar, Gabbro)
History: A single minimally weathered fusion-encrusted stone of 233 g was purchased in Tagounite, Morocco in November 2005.
Petrography and Geochemistry: (J. Wittke and T. Bunch, NAU; A. Irving, UWS) The specimen consists of a single yellow-green, relatively coarse-grained rock traversed by thin, black glass-rich veins. It is an olivine-rich, two-pyroxene cumulate gabbro composed of olivine (Fa31.7; FeO/ MnO = 96; 52 vol%), (Fs26.6Wo6.7; 23 vol%), augite (Fs16.2Wo29; 9 vol%), and plagioclase (An56; 14 vol%) with minor amounts of Ba-K feldspar, chromite, ilmenite, and merrillite. Larger pigeonite grains commonly enclose equant olivine grains, which contain abundant melt inclusions (0.025–0.125 mm). Plagioclase is partially converted to maskelynite, and pyroxenes and olivine exhibit shock lamellae and undulatory extinction. Note: This specimen is identical in texture and mineral composition to the gabbro clasts in NWA 773 and NWA 2700 and thus appears to be paired with those breccia specimens.
Classification: Achondrite (lunar, gabbro); minimal weathering.
