Northwest Africa 4362

Morocco

Find: 2005

Carbonaceous chondrite (CK5/6)

History:An anonymous finder collected the meteorite in the western part of the Sahara. The main mass holder purchased the sample in 2005 in Erfoud, Morocco.

Physical characteristics: One oriented stone of 60.1 g covered with fresh fusion crust was recovered.

Petrography: (A. Greshake, MNB). The meteorite shows a fine-grained texture with recrystallized matrix dominating over rare and mostly poorly defined chondrules and mineral fragments. Feldspar is abundant in the matrix and minor phases include Cr-rich magnetite and Ca-pyroxene.

Mineral compositions and geochemistry:Olivine (Fa29.9), low-Ca pyroxene (Fs25.5). Oxygen Isotopes (I. A. Franchi and R. C. Greenwood, OU): δ17O = -4.72, δ18O = -0.63, Δ17O = -4.39 (all ‰).

Classification: Carbonaceous chondrite (CK5/6); minimal shock, moderate to extensive weathering.

Type specimens: A total of 14.4 g plus one polished thin section are on deposit at MNB. HSSH holds the main mass.
