NWA 14930 meteorites were recovered out of the Saharan Desert of Morocco in April 2021. Samples were analyzed by Dr. Tony Iriving at the University of Washington's Dept. of Earth and Space Sciences. It was officially classified as a shocked L5 melt breccia. It has a two lithologies that comprise the L5 chondrite host and melted flow sections with a glassy texture. Large metal blebs (as opposed to smaller metal flecks) are seen, along with sparse chondrules in the first lithology. 

The specimen being offered here is a professionally-prepared, thick slice with a mirror polish. It is a showy piece with a lot of glittering metal that looks like stars set against a dark sky. It weighs 4.8 grams.

(Northwest Africa)

Purchased: 2021 Apr

History: Purchased 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.
