Writeup from MB 111:

Northwest Africa 14930 (NWA 14930)

(Northwest Africa)

Purchased: 2021 Apr

Classification: Ordinary chondrite (L5, melt breccia)

History: Purchased by Blaine Reed in April 2021 from a Moroccan dealer at the Tucson Gem and Mineral Show.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) The specimen is composed mainly of a very fine-grained, melt-textured chondritic assemblage containing blebby metal and sulfide, plus dispersed small lithic clasts of shock-darkened L5 chondrite material. Both lithologies are composed of equilibrated olivine and low-Ca pyroxene together with accessory kamacite (unaltered), sodic plagioclase, augite, chromite, troilite and chlorapatite.

Geochemistry: Olivine (Fa24.7±0.3, range Fa24.2-25.0, N = 6), low-Ca pyroxene (Fs20.9±0.2Wo1.7±0.2, range Fs20.6-21.3Wo1.3-1.8, N = 6), augite (Fs8.4Wo43.9).

Classification: Ordinary chondrite (L5-melt breccia). Clasts have shock stage S4.

Specimens: 87.2 g including one polished thin section at PSF; remainder with Reed.
