Writeup from MB 109:

Northwest Africa 13136 (NWA 13136)

Algeria

Find: 2017

Classification: Ordinary chondrite (L3)

History: Purchased in 2018 by Matthew Stream from Didi Baidari in Algeria.

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

Petrography: (D. Sheikh, FSU) Abundant chondrules (750±100 μm) and some clasts set in a fine-grained matrix containing accessory troilite, Fe oxides, and Fe-Ni metal.

Geochemistry: Olivine (Fa12.0-43.5, n=30), Low-Ca Pyroxene (Fs1.3-34.0 Wo0.2-2.1, n=60).

Classification: Ordinary Chondrite (L3) due to chondrule size and magnetic susceptibility.

Specimens: 21.78 grams at UCLA; main mass with Matthew Stream.
