Writeup from MB 112:

Northwest Africa 15062 (NWA 15062)

(Northwest Africa)

Purchased: 2018 Jul

Classification: Lunar meteorite (feldspathic breccia)

History: Purchosed by Bing’an Miao from a meteorite dealer Rex in Beijing in July, 2018.

Physical characteristics: The sample weighs 40.18 g and is brown in color.

Petrography: The polished section of this meteorite shows a granulitic brecciated texture. A large number of mineral fragments set in a granoblastic matrix dominated by plagioclase and small mafic minerals. The major minerals are plagioclase (62 vol%, partly transformed to maskelynite), olivine (26 vol%) and pyroxene (12 vol%), and the minor minerals are chromite, spinel and troilite.

Geochemistry: Plagioclase: An_96.1-98.5Or_0.05-0.25(n=21); Olivine: Fo_79.1-81.3, Fe/Mn=80-102 (n=11); Pyroxene: Fs_15-18.2Wo_1.9-16.8En_75.2-82.6, Fe/Mn=44-75(n=17)

Classification: Lunar (feldspathic breccia). Although there is no information on the exact location where NWA 15062 and NWA 15063 were found, they have similarities in lithic texture and major mineral composition, and they were purchased from the same meteorite dealer, so they may be paired meteorites.

Specimens: One polished thin section and the type sample of 8.5 g are deposited in GUT. The main mass of the meteorite is kept by the owner of Bing’an Miao.
