Writeup from MB 107:

Northwest Africa 5908 (NWA 5908)

(Northwest Africa)

Purchased: 2007

Classification: HED achondrite (Eucrite, brecciated)

History: The meteorite was purchased from a Moroccan meteorite dealer on the mineral fair in Munich, Germany.

Physical characteristics: Small dark-grayish individual partly covered with fusion crust.

Petrography: The meteorite is a fragmental breccia composed of basaltic clasts and up to 1 cm sized black impact melt clasts set into a fine-grained clastic matrix. Basaltic clasts and matrix are dominantly composed of exsolved pyroxene and plagioclase grains about 20 to 300 µm in size. Few matrix pyroxenes display magmatic zoning. Minor phases include chromite, ilmenite, pyrrhotite, silica and metallic iron.

Geochemistry: low-Ca pyroxene: Fs_42.1±3.6Wo_2.1±0.3(Fs_34.7-45.8Wo_1.8-3.0, n=12, FeO/MnO=36-42); Ca-pyroxene: Fs_27.1±1.0Wo_40.8±1.3(Fs_26.1-29.0Wo_37.9-42.1, n=12, FeO/MnO=31-36); calcic plagioclase: An_87.6±1.8(An_84.1-90.0, n=14)
