Writeup from MB 111:

Northwest Africa 6209 (NWA 6209)

(Northwest Africa)

Purchased: 2010 Feb

Classification: Ordinary chondrite (L3-5)

Petrography: (K. Metzler, IfP) Brecciated ordinary chondrite with moderate amounts of Fe-Ni metal, consisting of clasts of petrologic type 5 (up to 2 cm in size), embedded in chondritic material of petrologic type 3. Grain sizes of secondary plagioclase grains in the clasts mostly <50 µm.

Geochemistry: Mineral compositions and geochemistry: Mean compositions of olivine and Ca-poor pyroxene: Petrologic type 3 (host): Fa20.7±10.7 (Fa1.6-36.4; n=12); Fs14.6±6.3 Wo0.5±0.4 (Fs5.1-24.0Wo0.1-1.0; n=18). Clasts of petrologic type 5: Fa24.8±0.6 (Fa23.8-25.8; n=12); Fs21.0±0.3Wo1.0±0.3 (Fs20.6-21.3Wo0.5-1.3; n=5).

Classification: L chondrite, based on the metal content and mineral chemistry of the equilibrated chondrite clasts. Petrologic type of the clasts based on the equilibrated state of olivine and pyroxene and crystal size of secondary plagioclase.
