Chug Chug 107        22°29.183’S, 69°10.810’W

Antofagasta, Chile

Find: 2019

Classification: Ordinary chondrite (H5)

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

Physical characteristics: Total mass is about 168 g. The surface of the meteorite is dark brown.

Petrography: (Kseniya A. Konovalova, FMMR).Petrographic observation of polished section shows that the meteorite consists of coarse-grained matrix and rare small chondrules. The chondrules size vary from 200 to 300 µm. Plagioclase grains in matrix has are 20-40 µm in size. Olivine large crystalls have planar fractures without mosaicism (shock stage S3). Metal blebs and troilite with oxide products (weathering grade W1).

Geochemistry: Mineral composition and Geochemistry: EDS analyses (Atali Agakhanov, Ksenia Konovalova, FMMR). The primary chondrite paragenesis includes olivine 19.70±0.45 (N=25), Low-Ca pyroxene Fs17.8±0.8Wo1.22±0.29 (N=22), plagioclase Ab71.0An18.0Or4.5 (N=11). Composition of kamacite (in wt. %, n = 3): Fe - 92.90, Ni - 6.40, Co - 0.83, taenite (in wt. %, n = 2): Fe - 82.02, Ni - 16.85, Co - 0.64.

Classification: (Kseniya A. Konovalova, FMMR). Ordinary chondrite. H5, S3, W1.

Specimens: Atali Agakhanov holds main mass. 21.66 g and thin section, FMMR.
