Abbreviation: NWA 4799 Observed fall: No Year found: 2007 Country: Algeria Mass: 365 g Classification history: Meteoritical Bulletin: MB 94 (2008) Aubrite Recommended: Aubrite [explanation] This is 1 of 66 approved meteorites classified as Aubrite. [show all] Search for other: Achondrites, Aubrites, Enstatite achondrites, and Enstatite-rich meteorites Comments: Approved 17 Apr 2008 Writeup Writeup from MB 94: Northwest Africa 4799 Algeria Find: May 2007 Achondrite (aubrite) History: Purchased by Greg Hupé in May and October 2007 from a Moroccan dealer in Tagounite. Physical characteristics: Eighty-six light brown stones and fragments (total 365 g); most are complete, some are broken, and some have remnant fusion crust. Petrography: (A. Irving and S. Kuehner, UWS) The overall texture is that of a brecciated igneous rock, with larger angular to rounded clasts (some showing cumulus texture) in a matrix of smaller grains. The dominant mineral is pure enstatite with lesser amounts of interstitial albite (some in graphic intergrowths with a silica polymorph) and accessory Si-bearing kamacite, Ti-Cr-bearing troilite, oldhamite, niningerite, Ti-bearing daubreelite and schreibersite. The enstatite grains exhibit polysynthetic twinning indicative of inversion from former clinoenstatite. Grain boundary coatings of goethite or limonite and orange staining along enstatite cleavage planes, as well as veinlets of calcite, are evidently products of terrestrial desert weathering. Geochemistry: Enstatite (En99.5Fs0.1Wo0.4), kamacite (Fe 92.1 wt%, Ni 4.5 wt%, Si 3.4 wt%). Classification: Achondrite (aubrite). Specimens: A total of 20.1 g and one polished thin section are on deposit at UWS. GHupé holds the main mass.
