The Meteoritical Bulletin, No. 105
Mass: 2014 g
meteorite (feldspathic breccia)
Purchased by Jay Piatek in Morocco, 2016.
characteristics: Single stone, weathered exterior without
fusion crust; broken surface reveals numerous white feldspathic clasts set
in a dark-gray groundmass.
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.
