Writeup from MB 104:

Northwest Africa 10375 (NWA 10375)

(Northwest Africa)

Purchased: 2015

Classification: Martian meteorite (Shergottite)

History: The meteorite was purchased from the meteorite dealer Med Lamine Ahmed.

Physical characteristics: Four small greenish individuals lacking any fusion crust were recovered from the northwestern Sahara.

Petrography: The meteorite displays a coarse-grained basaltic texture and is dominantly composed of blocky up to 1.5 mm sized clinopyroxene and plagioclase grains. Pyroxene shows complex patchy zoning, fine exsolution lamella and strong mosaicism. Often chromite inclusions are found enclosed in pyroxene. Plagioclase is intermediate in composition and converted into maskelynite due to strong shock metamorphism. Minor phases include ilmenite, ulvöspinel, and merrillite.

Geochemistry: Pyroxene: Fs40.1±14.1Wo21.7±8.6 (Fs20.5-62Wo12.4-34.5, n=36, FeO/MnO=24-38); feldspar: An50.1±3.6Ab47.2±1.4 (An40-53.6Ab44.2-50, n=23)

Classification: Martian, basaltic shergottite
