Acfer 402        27°30’42.7"N, 3°56’54.7"E

Tamanghasset, Algeria

Find: 2019 Nov

Classification: Carbonaceous chondrite (CV3)

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

Geochemistry: Most olivine in chondrules and AOAs is Fo-rich. The average composition of these olivines is Fa4.2±4.8 (range: Fa0-22; N=24). Low-Ca pyroxene is Fs2.0±1.0 (range Fs1-5; n=10).

Classification: Carbonaceous chondrite (CV3)
