Description: Hello up for sale is NWA 13788, classified as a Lunar Melt Breccia!! This meteorite was found in December, 2020 near Ouargla Algeria, its a rather large find with many dark stones on the surface and light colored stones buried in the sand. This gorgeous shapedendcut weighs 10.222 grams, beautiful high quality piece with polished surface and insane melted matrix. The impact melt texture of the sample would suggest that it was melted by impacts while either on the surface of the moon, or was excavated from the near-surface. The area it came from had to have been impacted at least twice; once to cause the melting, and a second time to launch it out of orbit. This lunar meteorite appears to have sampled near-surficial material from the moon with contribution from exogenous impactor material. This comes with a COA card and display case. Thanks for your interest and take care. Name:Northwest Africa 13788 This is an OFFICIAL meteorite name.

Comments:Approved 28 Mar 2021 Writeup from MB 110: Northwest Africa 13788(NWA 13788) Ouargla, Algeria Find: 2020 Dec Classification: Lunar meteorite (melt breccia) History: Purchased in 2021 by Matthew and Travis Stream from a meteorite dealer in Algeria. Physical characteristics: Specimen contains a dark-brown fusion crust. An interior slice reveals light and dark clasts within a darker matrix. Petrography: (D. Sheikh,FSU) Sample is an impact melt breccia composed of angular to sub-rounded mineral and lithic clasts (<4 mm) set in a predominantly vitreous matrix composed of brown, flow-banded, vesicular, partly devitrified glass and fine-grained crystalline impact melt. Lithic clasts consist primarily of anorthitic plagioclase (some partially coverted to maskelynite) with smaller quantities of olivine, pigeonite, low-Ca pyroxene, sub-calcic augite, and Si-Na-Ca-Mg-rich glass; a variety of lithic clasts were observed to display poikilitic, granulitic, dendritic, porphyritic, or subophitic textures in thin section. Accessory phases present include kamacite, troilite, chromite (some containing Ti), and ilmenite. Classification: Lunar (melt breccia).
