Northwest Africa 13321 (NWA 13321)

Morocco

Find: 2018 Mar

Classification: Carbonaceous chondrite (CV3)

Petrography: Chondrite with large chondrules (~mm), AOAs, and CAIs set in an abundant fine-grained Fe-rich matrix. Opaque minerals include sulfides and metals. Metals are often included within the chondrules. Opaque areas between the chondrules contain abundant terrestrial alteration products.

Geochemistry: Most olivine in chondrules and AOAs is Fo-rich. The average composition of these olivines is Fa3.7±4.6 (range: Fa0-23; N=22). Low-Ca pyroxene is Fs1.6±0.7 (range Fs0-4; n=12).

Classification: Carbonaceous chondrite (CV3)
