Writeup from MB 93:

Northwest Africa 3190

Northwest Africa

Find: 2006

Achondrite (lunar, mingled breccia)

History and Physical characteristics: A. Aaronson purchased a 40.7 g partially crusted, complete stone in Rissani, Morocco, in December 2006. The hand specimen exhibits an abundance of large (between 0.6 and 2.1 mm in diameter) anorthositic clasts. The weathered portion of the crust is pale vermillion to light brown; the fresher crust is dark gray to black.

Petrography: (T. Bunch and J. Wittke, NAU; A. Irving, UWS) This mingled breccia contains anorthositic lithologies that include anorthosite, anorthositic norites, gabbros, and troctolites, in addition to variolitic and subophitic basalt clasts, breccia-within-breccia clasts, and an abundance of olivine and plagioclase fragments. Melt and fragmental matrices are heterogeneously distributed. The interior shows very low weathering effects.

Mineral compositions: Anorthositic norite orthopyroxene (Fs_28.5Wo_3.8; FeO/MnO = 65). Olivine gabbro contains olivine (Fa_26.2; FeO/MnO = 96), plagioclase (An_92.3), subcalcic pyroxene (Fs_21.6Wo_14.4; FeO/MnO = 48), and ilmenite with MgO = 6.5 wt%. Variolitic basalt has olivine (Fa_35.7; FeO/MnO = 103), pigeonite (Fs_24.6Wo_8.7) and plagioclase (An_95.5). Bulk composition: (R. Korotev, WUSL) FeO = 9.6 wt%, Sm = 3.9 ppm, Th = 1.4 ppm, Ir = 6.5 ppb.

Classification: Achondrite (lunar, mingled breccia). Probably paired with NWA 2995, based on essentially identical bulk compositions.

Type specimens: A total of 8.8 g is on deposit at NAU. The main mass holder is anonymous.

Submitted by: T. Bunch, NAU.
