Writeup from MB 102:

Northwest Africa 8000 (NWA 8000)

(Northwest Africa)

Purchased: 2013 Jun

Classification: HED achondrite (Diogenite)

History: Purchased by Stefan Ralew in June 2013 from a dealer in Agadir, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Relatively coarse grained, equigranular assemblage of predominantly orthopyroxene plus ~10 vol.% calcic plagioclase with accessory clinopyroxene, chromite and troilite.

Geochemistry: Orthopyroxene (Fs34.1-34.2Wo2.4-2.5, FeO/MnO = 28-31), plagioclase (An88.1-89.0Or0.5-0.2), clinopyroxene (Fs13.6-13.8Wo43.3-43.4, FeO/MnO = 25-26).

Classification: Diogenite (noritic). Like NWA 6928, this is a rare example of a noritic lithology related to diogenites.

Specimens: 4.76 g and one polished thin section are at UWB. The remainder is held by Mr. S. Ralew.
