Writeup from MB 106:

Northwest Africa 11050 (NWA 11050)

(Northwest Africa)

Purchased: 2006 Jun

Classification: HED achondrite (Eucrite, monomict)

History: Purchased from a Moroccan dealer at the mineral fair in Sainte-Marie-aux-Mines, France.

Physical characteristics: Many fragments with remnants of fusion crust.

Petrography: (K. Metzler, IfP) Monomict breccia consisting of eucritic lithic clasts with ophitic to subophitic textures set in a fine-grained clastic matrix of related debris. Pyroxene crystals with thin augite exsolution lamellae. Lithic clasts frequently contain melt pockets consisting of a silica polymorph, ilmenite, and troilite.

Geochemistry: Mineral compositions and geochemistry: Eucritic pyroxene (host): Fs57.3±0.6Wo2.9±0.2 (Fs56.4-58.0Wo2.7-3.2, n=11). Eucritic pyroxene (exsolution lamellae) Fs27.4±0.6Wo41.5±0.7 (Fs26.6-28.5Wo40.4-42.4, n=9). Plagioclase An86.0±2.9Or0.7±0.6 (An80.3-89.1Or0.0-2.1, n=10).
