Description from the seller
Northwest Africa 8681 (NWA 8681)
(Northwest Africa)
Purchased: 2014 Jun
Classification: HED achondrite (Eucrite, brecciated)
History: Purchased by Sergey Vasiliev from a Moroccan dealer at the Ensisheim Show in June 2014.
Physical characteristics: Single stone (590 g) with a light reddish-brown weathered exterior. The interior is dark gray with whitish clasts visible.
Petrography: (A. Irving and S. Kuehner), UWS) Breccia consisting of gabbroic eucrite clasts set in a very dark brown matrix containing related crystal debris plus minor unexsolved pigeonite. Gabbroic eucrite clasts are composed of exsolved pigeonite (commonly with wavy clinopyroxene exsolution lamellae), polycrystalline calcic plagioclase, silica polymorph, chromite, ilmenite and Ni-free metal. Secondary minerals from terrestrial weathering include, barite, calcite and iron hydroxides.
Geochemistry: Orthopyroxene host crystals (Fs61.0-62.2Wo4.4-2.1, FeO/MnO = 32-35, N = 3), clinopyroxene exsolution lamellae (Fs26.8-28.3Wo43.6-42.5, FeO/MnO = 30-33, N = 3), pigeonite (Fs36.2Wo5.6, FeO/MnO = 23).
Classification: Eucrite (brecciated). Likely paired with NWA 7989, NWA 8036, NWA 8588 and related stones.
Specimens: 24.8 g including one polished thin section at UWB; main mass with Mr. S. Vasiliev.
