Northwest Africa 8001

(Northwest Africa)
Purchased: 2013 June
Mass: 23.4 g

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Darryl Pitt in June 2013 from a Moroccan dealer.

Petrography: (A. Irving and S. Kuehner, UWS) Complex polymict breccia composed of angular mineral clasts, some mare basalt clasts and glass spheres in a fine grained matrix. Sparse grains of forsterite are present; other minerals are more ferroan olivine, low-Ca pyroxene, subcalcic augite, anorthite, ilmenite and troilite.

Geochemistry: Forsterite (Fa5.7-9.0; FeO/MnO = 91-104), ferroan olivine (Fa39.7-47.7; FeO/MnO = 89-95), low-Ca pyroxene (Fs31.2-33.5Wo5.6-3.9; FeO/MnO = 56-63), subcalcic augite (Fs17.2-44.4Wo36.5-26.6; FeO/MnO = 49-62), subcalcic ferroaugite (Fs58.8Wo33.4; FeO/MnO = 72), anorthite (An96.8-97.3Or0.1-0.2). Bulk composition (R. Korotev, WUSL): INAA of subsamples gave mean abundances of FeO 4.8 wt.%, and (in ppm) Sc 9, La 7.9, Sm 3.7, Eu 0.96, Yb 2.7, Th 1.3.

Classification: Lunar (mingled regolithic breccia). Olivine as magnesian as that present in this meteorite is unknown among other lunar specimens.

Specimens: 4.7 g and one polished thin section are at UWB. The remainder is with DPitt.
