Northwest Africa 2828Basic informationName: Northwest Africa 2828 This is an OFFICIAL meteorite name. Abbreviation: NWA 2828 Observed fall: No Year found: 2005 Country: (Northwest Africa) Mass: 8.67 kg Classification history:Meteoritical Bulletin: (2007) AubriteRecommended: EL-melt rock This is 1 of 23 approved meteorites classified as EL-melt rock. Comments:Approved 11 Jun 2006 Revised 1 Sep 2019: Reclassified by Rubin (2016) Northwest Africa 2828Mauritania or AlgeriaFind: December 2005Achondrite (aubrite)History: Purchased in December 2005 by Greg Hupé from a Moroccan dealer in Tagounite.Physical characteristics: Thirty-six pale gray to whitish stones lacking fusion crust with a total weight of 8672 g. Several stones have exterior light orange staining, and two stones contain one or two dark brown cross-cutting veins (1–2 mm wide) of magnetic, fine-grained iron oxide and hydroxide minerals.Petrography: (A. Irving and S. Kuehner, UWS) Monomict microbreccia, which is mostly fairly uniform but contains sporadic small, rounded clasts (up to 4 mm across). Relatively fine but variable grain size (0.3–1.5 mm), and composed predominantly of bladed grains of essentially pure enstatite (exhibiting lamellar twinning) with ~15 vol% oligoclase, accessory altered troilite with fresh, subparallel exsolution blades of daubreelite, and sporadic rounded to ellipsoidal grains of graphite (up to 1.2 mm across). Small (<0.2 mm) lobate cavities partly filled with fine-grained calcite, silica, and an Fe-bearing mineral are present in the interior of even the freshest stones, and may represent former oldhamite grains. Small grains found as inclusions within enstatite are fresh Ti-free troilite, pure Mn-alabandite, daubreelite, fresh oldhamite (some Mn-bearing), schreibersite, and very rare specks of kamacite and taenite. Minor barite and calcite are present, probably the products of terrestrial weathering.
