Northwest Africa 10666 (NWA 10666)

(Northwest Africa)

Purchased: 2015 Oct

Classification: HED achondrite (Diogenite)

History: Purchased by Gary Fujihara in October 2015 from a Moroccan dealer.

Physical characteristics: A single fusion crusted stone (46.83 g); the fresh interior is mostly beige with some white and black grains visible.

Petrography: (A. Irving and S. Kuehner, UWS) Coarse-grained aggregate of predominantly orthopyroxene with ~6 vol.% calcic plagioclase and accessory clinopyroxene, chromite, troilite and rare ilmenite. Both orthopyroxene (which is notably ferroan) and plagioclase exhibit marked undulose extinction.

Geochemistry: Orthopyroxene (Fs35.1-35.2Wo2.2-1.9, FeO/MnO = 29, N = 3), clinopyroxene (Fs14.3-14.4Wo43.5-43.3, FeO/MnO = 21-24, N = 2), plagioclase (An81.3Or3.0; An86.3Or0.6; N = 2).

Classification: Diogenite (feldspathic).

Specimens: 9.56 g including one polished thin section at UWB; remainder with Mr. G. Fujihara.
