Writeup from MB 109:

Northwest Africa 13388 (NWA 13388)

Morocco

Find: 2019

Classification: Ordinary chondrite (L5)

History: Purchased online in 2019 by Daniel Sheikh from a seller in Morocco.

Physical characteristics: Sample contains a dark-brown fusion crust.

Petrography: (D. Sheikh, FSU) Sample is an equilibrated ordinary chondrite with blurred chondrule boundaries (Av. 700±50 µm, n=6) and contains olivine, orthopyroxene, Fe-Ni metal, troilite, iron oxide, and secondary recrystallized plagioclase (12±4 µm).

Geochemistry: Olivine (Fa22.8±0.5, n=14), Orthopyroxene (Fs20.9±0.8Wo1.2±0.3, n=15).

Classification: Ordinary Chondrite (L5) Based on Fa and Fs homogeneity, secondary recrystallized plagioclase grain size, and magnetic susceptibility.

Specimens: 21.01 grams at UCLA; main mass with Daniel Sheikh.
