Writeup

Writeup from MB 103:

Northwest Africa 8326 (NWA 8326)

(Northwest Africa)

Purchased: Dec 2013

Classification: HED achondrite (Diogenite)

Physical characteristics: The eight individuals are partly to totally covered by black fusion crust and show a light greyish interior.

Petrography: The meteorite displays a pronounced cumulate texture of predominantly large orthopyroxene and plagioclase crystals. Orthopyroxene is heavily fractured and plagioclase partly converted to maskelynite due to shock. Accessory minerals include augite, SiO₂ polymorphs, chromite and troilite.

Geochemistry: low-Ca pyroxene: Fs_35.5±0.4Wo_2.5±0.5(Fs_34.4-36.1Wo_1.7-4.2, n=17), FeO/MnO: 26-32; Ca-pyroxene: Fs_14.9±0.2Wo_43.8±0.2(Fs_14.6-15.1Wo_43.5-44, n=10), FeO/MnO: 22-26; clacic plagioclase: An_84.4±1(An_83.2-86.3, n=12)
