Gandom Beryan 012 31°52.223’N, 57°08.846’E Kerman, Iran Find: 3 Jan 2017 Classification: Ordinary chondrite (H5) History: The meteorite was found 3 January 2017 by the UrFU meteorite expedition-2017 in Iran (Pastukhovich A.Yu., Larionov M.Yu., Kruglikov N.A., Zamyatin D.A.) in the northern sandy part of the Lut desert. Physical characteristics: A dark-brown fragment with angular shape. The surface and interior of the meteorite is light to dark brown in color due to abundant Fe-hydroxides. Some parts have glassy-like surface due to desert weathering. No fusion crust was observed. Petrography: Classification (K. Dugushkina, RAS-UB). Chondrite with recrystallized texture. Predominantly porphyritic olivine (PO) and porphyritic olivine-pyroxene (POP) chondrules. Weathering grade is W3, heavy oxidation of metal and troilite. There is a network of thin metal-troilite shock veins in fractures in olivine, pyroxene and plagioclase. Plagioclase is not melted. Shock stage is S3/4. Geochemistry: EDX analyses by K. Dugushkina, RAS-UB. The chondrite paragenesis includes olivine Fa16.9±1.9 (N=33), orthopyroxene En84.7±0.8Fs14.2±0.7Wo1.1±0.2 (N=17), clinopyroxene En44.7±1.1Fs6.7±0.7Wo44.7±1.1 (N=4), plagioclase An23.3±1.5 (N=8), chromite, apatite, troilite, taenite and kamacite. The average composition of chromite (N=5): Cr2O3 57.4±0.3 wt%, FeO 27.3±0.3 wt%, MgO 4.6±0.3 wt%, Al2O3 7.4±0.6 wt%, TiO2 1.7±0.3 wt%, SiO2 0.7±0.3 wt%, NiO 0.1±0.04 wt%. Classification: (K. Dugushkina, RAS-UB) H5, ordinary chondrite. Specimens: 293 g sample and 4.19 g cut-off and thin section UrFU | ||||||||||||||||||||||||||||||||||||
