Northeast Africa 014 (NEA 014)


Purchased: 2020 Aug

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased in August 2020 from a Libyan dealer.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed of mineral clasts of anorthite, relatively abundant exsolved pigeonite and subordinate olivine set in a very fine grained matrix (sparsely vesicular) containing ilmenite, aluminous chromite, troilite and taenite. Pyroxene grains consist of augite lamellae within orthopyroxene or pigeonite hosts.

Geochemistry: Orthopyroxene host (Fs28.4-31.0Wo3.1-3.3, FeO/MnO = 54-61, N = 3), pigeonite host (Fs36.7Wo9.3, FeO/MnO = 65), pigeonite lamella (Fs27.2Wo21.5, FeO/MnO = 67), augite lamellae (Fs13.1-19.1Wo40.1-40.9, FeO/MnO = 50, N = 2), olivine (Fa21.0-23.5, FeO/MnO = 81-103, N = 3), anorthite (An95.6-97.1Or0.1, N = 3).

Classification: Lunar (feldspathic breccia, olivine-poor).

Specimens: 20.5 g including one polished mount at UWB; remainder with Labenne.
