Northwest Africa 10734 (NWA 10734)

(Northwest Africa)

Purchased: 2016

Classification: HED achondrite (Eucrite, brecciated)

History: The meteorite was bought in 2016 from a local meteorite dealer in Erfoud, Morocco.

Petrography: The meteorite is brecciated eucrite composed of basaltic and melt clasts set into a more fine-grained clastic matrix. Dominant minerals are exsolved pyroxene, pigeonite displaying compositional zoning and plagioclase grains of variable grain size ranging from 0.1 to 0.5 mm. Accessories include chromite and silica.

Geochemistry: Pyroxene host to augite lamellae: Fs58.5±0.8Wo3.4±1.5 (Fs57.2-59.5Wo2.1-6.1, n=10, FeO/MnO=32-38); Ca-pyroxene: Fs33.8±1.8Wo35.3±2.2 (Fs19.6-27.6Wo35.7-46.4, n=14, FeO/MnO=30-37); zoned pigeonite: Fs43.1±8.3Wo8.8±3.3 (Fs33.0-56.2Wo6.4-18.3, n=19, FeO/MnO=30-34); calcic plagioclase: An91.4±2.0 (An87.7-93.4, n=15)
