Writeup from MB 100:

Northwest Africa 6292 (NWA 6292)

(Northwest Africa)

Found: 2010

Classification: Ungrouped achondrite

History: Purchased in June 2010 by Marc Jost from a Moroccan dealer

Physical characteristics: A single brownish, dense 725 g stone

Petrography: (A. Irving and S. Kuehner, UWS) Protogranular texture. Aggregate of predominantly olivine with subordinate orthopyroxene, clinopyroxene, chlorapatite, chromite, partly altered kamacite and troilite.

Geochemistry: Olivine (Fa30.2-30.3; FeO/MnO = 51.7-53.5), orthopyroxene (Fs24.1-24.3Wo1.9-2.0; FeO/MnO = 36.9-41.1), clinopyroxene (Fs9.4Wo44.1; FeO/MnO = 27.9; Al2O3 = 0.75 wt.%; Cr2O3 = 0.91 wt.%). Oxygen isotopes (D. Rumble, CIW): δ17O 2.42; δ18O 4.55; Δ17O +0.031 per mil

Classification: Achondrite (ungrouped, brachinite-like). This specimen has the same mineralogy and oxygen isotopic composition as NWA 5400, and is paired with it.

Specimens: A total of 21 g and one polished thin section are on deposit at UWS. The main mass is held by Marc Jost.
