Northwest Africa 8055 (NWA 8055)

(Northwest Africa)

Purchased: 2013 Sep

Classification: Lunar meteorite (feldspathic breccia)

History: Purportedly found near Boujdour and purchased in Agadir, Morocco, by Adam Aaronson in September 2013.

Physical characteristics: A single stone (98 g) broken into three pieces that fit together. Small white clasts are visible in a dark gray matrix.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia consisting of numerous mineral fragments and rare ophitic-textured, basalt clasts in a finer grained matrix. Minerals are anorthite, olivine, unexsolved pigeonite, subcalcic augite, augite, exsolved pigeonite, ilmenite, Ti-rich chromite, troilite, and rare kamacite and barite. Sparse clasts composed of intergrown fayalite+hedenbergite+silica polymorph are present.

Geochemistry: Olivine (Fa19.8-38.8, FeO/MnO = 86-105), pigeonite (Fs47.0Wo19.6, FeO/MnO = 59), subcalcic augite (Fs39.9Wo33.2, FeO/MnO = 58), augite (Fs52.0Wo41.9, FeO/MnO = 74). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave (in wt.%) FeO 5.9, Na2O 0.42, and (in ppm) Sc 14.8, La 1.9, Sm 0.98, Eu 0.93, Yb 1.0, Th 0.2.

Classification: Lunar (feldspathic fragmental breccia).

Specimens: 19.6 g (including a polished end-cut specimen and a polished mount) are at UWB. The remainder is held by Aaronson.
