Writeup from MB 104:

Northwest Africa 10444 (NWA 10444)

(Northwest Africa)

Purchased: 2015 May

Classification: HED achondrite (Howardite)

History: Purchased by Fabien Kuntz in May 2015 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Fresh fragmental breccia containing some basaltic eucrite clasts but mostly composed of related mineral fragments plus some diogenitic orthopyroxene (~12 vol.%). Minerals include calcic plagioclase, exsolved pigeonite, fayalite, Ti-Al-chromite, troilite and ilmenite (some in intergrowths with Ni-free metal, troilite and silica polymorph).

Geochemistry: Orthopyroxene host (Fs61.0Wo3.3, FeO/MnO = 30), augite exsolution lamella (Fs28.3Wo42.4, FeO/MnO = 29), augite host (Fs30.5Wo39.8, FeO/MnO = 30), low-Ca pyroxene exsolution lamella (Fs56.4Wo7.7, FeO/MnO = 29), diogenitic orthopyroxene (Fs27.9Wo3.6; Fs42.4Wo1.9; FeO/MnO = 30-31, N = 2), fayalitic olivine (Fa70.8-72.7, FeO/MnO = 44-45, N = 2).

Classification: Howardite.

Specimens: 21.72 g including one polished thin section at PSF; remainder with Kuntz.
