Chug Chug 110        22°29.177’S, 69°11.081’W

Antofagasta, Chile

Find: 25 Oct 2019

Classification: Ordinary chondrite (LL6)

History: The meteorite (1 piece) was found in autumn 2019 by Atali Agakhanov during a meteorite searching expedition organized by Timur Kryachko.

Physical characteristics: Total mass is about 350 g. The exterior is dark brown whereas the interior of meteorite is grey-brown with visible metal.

Petrography: (Kseniya A. Konovalova, FMMR). Petrographic observation of a polished section shows that the main part of meteorite consist of coarse-middle matrix with very rare chondrules. The mineral matrix are olivine, low-Ca pyroxene and maskelynite (>60 µm) with minor amounts metal and troilite. Chromite-plagioclase object (about 1.1 mm) was also observed in the matrix. Metal partially oxidized (weathearing grade W1).

Geochemistry: Mineral composition and Geochemistry: EDS analyses (Atali Agakhanov, Ksenia Konovalova, FMMR). The primary chondrite paragenesis includes olivine 26.64±0.58 (N=15), Low-Ca pyroxene Fs23.0±1.0Wo1.58±0.19 (N=17), high-Ca pyroxene Fs16.1±0.4Wo44.60±0.28 (N=3), maskelynite Ab79.7An14.7Or5.5 (CaO - 2.11-2.49 wt. %, N=3). Composition of kamacite (in wt. %, n = 3): Fe - 93.19, Ni - 5.52, Co - 1.46, chromite Crt74.03Spl8.62 (N=3)

Classification: (Kseniya A. Konovalova, FMMR). Ordinary chondrite. LL6, S4, W1.

Specimens: Atali Agakhanov holds main mass. 22.97 g and thin section - FMMR
