Writeup from MB 109:

Northwest Africa 13282 (NWA 13282)

Western Sahara

Find: 2018

Classification: Ordinary chondrite (L3)

History: Found in Western Sahara in late 2018. Purchased on January 11, 2019, by John Higgins from a meteorite dealer in Morocco.

Physical characteristics: Single stone with dark-brown fusion crust.

Petrography: (D. Sheikh, FSU) Sample is a chondrite composed of well-defined chondrules (Av. 750±50 µm) set in a dark, fine-grained matrix containing silicates, Fe-Ni metal, troilite, and chromite. Most chondrules contain devitrified mesostasis.

Geochemistry: Olivine (Fa22.1±5.7, range Fa3.1-28.7, n=26), Low-Ca Pyroxene (Fs14.0±5.8Wo0.8±0.5, range Fs2.2-20.4Wo0.2-2.2, n=16).

Classification: Ordinary Chondrite (L3) due to chondrule size, Fa,Fs heterogeneity, and magnetic susceptibility.

Specimens: 22.25 grams at UCLA; main mass with John Higgins.
