Writeup from MB 104:

Northwest Africa 10411 (NWA 10411)

(Northwest Africa)

Purchased: 2015

Classification: HED achondrite (Howardite)

History: Purchased by John Higgins in August and September 2015 from Moroccan dealers.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed mostly of diogenite debris plus ~12 vol.% of eucrite clasts (with intersertal textures) and related debris. Minerals are orthopyroxene, chromite, exsolved pigeonite, calcic plagioclase, olivine, silica polymorph, chromite, ilmenite and troilite, plus rare zircon and Ni-free metal.

Geochemistry: Olivine (Fa43.1-44.1, FeO/MnO = 53-54, N = 2), diogenitic orthopyroxene (Fs22.1-24.4Wo2.1-2.4, FeO/MnO = 31, N = 3), orthopyroxene host (Fs52.4Wo3.5, FeO/MnO = 30), clinopyroxene exsolution lamella (Fs24.2Wo39.0, FeO/MnO = 26), orthopyroxene host (Fs40.6Wo3.1, FeO/MnO = 28), clinopyroxene exsolution lamella (Fs19.6Wo42.1, FeO/MnO =27).

Classification: Howardite.

Specimens: 26.9 g including one polished thin section at UWB; remainder with Mr. J. Higgins.
