Purchased: 2018

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased in March 2018 by Dustin Dickens from a meteorite dealer in Mali.

Physical characteristics: Several identical appearing dark stones covered partially with a milky-green fusion crust. Broken surface reveals a fragmental breccia with numerous white feldspathic clasts set in a dark colored ground mass.

Petrography: (C. Agee, UNM) This meteorite is a breccia of primarily feldspathic clasts, with lesser amounts of olivine and pyroxene fragments. The shock melt composition has a very high alumina content, vesicles occur throughout.
