Writeup from MB 95:
Northwest Africa 5406
Find: July 2008
Achondrite (lunar, feldspathic breccia)
History: Purchased by Greg Hupé in July 2008 from a dealer in Ouarzazate, Morocco, who reported that these stones were found in the same area as NWA 4936 near Siksou Mountain in southern Morocco.
Physical characteristics: Six, dark gray, mostly very fine-grained stones (total weight 281 g) with hackly fracture and lacking obvious fusion crust. The interior of each stone resembles devitrified glass with dispersed small white clasts.
Geochemistry: Pigeonite (Fs34.7Wo9.8, FeO/MnO = 59.9), augite (Fs55.8Wo26.4, FeO/MnO = 72.6), olivine (Fa25.7–27.0, FeO/MnO = 85.3–120), plagioclase (An96.2–97.2Or0.0). Bulk composition (R. Korotev, WUSL): FeO 5.8 wt%, Th 2.0 ppm, Sc 9.1 ppm, Ni 520 ppm, Sm 6.3 ppm.
Classification: Achondrite (lunar, feldspathic breccia). These stones have essentially the same distinctive textures, mineral compositions and bulk composition as NWA 4936, and are almost certainly paired with the latter stones.
Specimens: A total of 20.0 g of is on deposit at UWS. The main masses are held by Mr. G. M. Hupé.
