Writeup from MB 104:
Jiddat al Harasis 910 (JaH 910) 19°43.14’N, 55°48.52’E Al Wusta, Oman Find: 2011 Feb 25 Classification: Martian meteorite (Shergottite) History: The meteorite was found in 2011 during a field trip in the Oman desert. Petrography: The meteorite displays a speckled black-greenish interior and is dominantly composed of blocky, up to 0.5 mm-sized clinopyroxene and plagioclase grains. Pyroxene shows complex patchy zoning, fine exsolution lamella and strong mosaicism. Plagioclase is intermediate in composition and recrystallized to tiny grains with strong undulatory extinction. There is no maskelynite present. Plagioclase is largely anisotropic showing a crystalline fibrous appearance similar to that observed in Dhofar 378, suggesting recrystallization after shock. Accessory minerals include ilmenite, ulvöspinel, pyrrhotite, and merrillite; shock-melt pockets are present. Geochemistry: pigeonite: Fs52.8±5.2Wo14.5±1.8 (Fs41.4-60.4Wo12-20.6, n=20), FeO/MnO=30-36; augite: Fs31.1±7Wo31.9±2.1 (Fs19.5-41Wo28.6-35.9, n=20), FeO/MnO=25-35; plagioclase: An51.5±2.9Or1.4±0.8 (An45.4-57.1Or0.4-3.6, n=18). | ||||||||||||||||||||||||||||||||
