meteorite (feldspathic breccia)
History:
Purchased by Jay Piatek in Morocco, 2016.
Physical
characteristics: Single stone, weathered exterior
without fusion crust; broken surface reveals numerous white feldspathic
clasts set in a dark-gray groundmass.
Petrography:
(C. Agee, UNM) Microprobe
examination of a polished mount shows a fragmental breccia with numerous
olivine, pigeonite, and augite grains set in a dominant feldspathic matrix.
Lithic and melt clasts also observed. Pigeonite, augite, and olivine show
igneous crystallization, iron-enrichment trends.

(C. Agee and S. Spilde, UNM) Olivine Fa22.2±15.5, Fe/Mn=91±7, n=15;
pigeonite Fs32.3±10.6Wo5.7±3.4, Fe/Mn=58±4, n=7;
augite Fs21.2±13.4Wo39.1±5.3, Fe/Mn=50±14, n=3;
plagioclase An95.3±2.4, n=2.
Classification:
Lunar feldspathic breccia.
Specimens:
20.8 g including a probe mount on deposit at UNM, Jay Piatek holds the main mass.
