Los Vientos 363 (LoV 363)        24°38.659’S, 69°52.231’W

Antofogasta, Chile

Find: 4 Nov 2019

Classification: Ordinary chondrite (L5)

History: One fragment of meteorite (14 g) was found 4 November 2019 by the KFU meteorite expedition-2019 in Chile (Nurgaliev D., Kuzina D., Kuzin D., Pastukhovich A.).

Physical characteristics: Total mass is 14.0 g. The meteorite has roughly rounded shape. Exterior of the stone is desert polished. The surface and interior of the meteorite is light to dark brown in color due to Fe-hydroxides. No fusion crust was observed.

Petrography: (Kseniya Dugushkina, RAS-UB) The meteorite has a dark-brown color. The meteorite consists mainly of a fine-grained, inequigranular, recrystallized matrix; chondrules make up 20% of the volume. Predominant porphyritic olivine (PO) and porphyritic olivine-pyroxene (POP) chondrules. Chondrules have vague boundaries. Chromite-plagioclase assemblages are found in recrystallized matrix. The assemblages range in size from 10-450 µm and consist of 0.2-30-µm rounded and euhedral chromite grains surrounded by plagioclase. Heavy oxidation of metal and troilite, 60-95% being replaced (W3). Shock stage is S1.

Geochemistry: EDX analyses by Kseniya Dugushkina, RAS-UB. The chondrite paragenesis includes olivine Fa25.2±0.8 (N=27), orthopyroxene En77.8±0.3Fs20.6±0.3Wo1.6±0.3 (N=22), clinopyroxene En47.4±1.2Fs8.8±1.1Wo43.8±1.4 (N=9), plagioclase An26.8±1.9 (N=16), chromite, apatite, troilite, taenite (Ni 27.9-35.9%) and kamacite (Ni 6.3-6.4%). The average composition of chromite (N=5): Cr2O3 56.6±0.9 wt%, FeO 30.1±1.1 wt%, MgO 2.7±0.4 wt%, Al2O3 6.7±0.4 wt%, TiO2 2.5±0.5 wt%, MnO 0.7±0.1 wt%, SiO2 0.5±0.2 wt%.

Classification: Ordinary chondrite, L5.

Specimens: 12.39g 1 sample and 1.61 g cut-off and thin section UrFU
