Writeup from MB 109:

Northwest Africa 13322 (NWA 13322)

Morocco

Find: October 2019

Classification: Carbonaceous chondrite (CV3)

Petrography: Chondrite with large chondrules (~1 mm), AOAs, and CAIs set in abundant fine-grained Fe-rich matrix. Main silicates include olivine, low-Ca, and Ca-pyroxene. Opaque areas are basically made of terrestrial alteration products, although some sulfides are still visible.

Geochemistry: Most olivine in chondrules and AOAs is Fo-rich. The average composition of these olivines is Fa3.7±2.7 (range: Fa0-12; N=23). Low-Ca pyroxene is Fs 2.0±1.4 (range Fs0-6; n=12).

Classification: Carbonaceous chondrite (CV3)
