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 241 g. The interior and surface are rusty brown to dark brown.

Petrography: (K.A. Konovalova, FMMR). Petrographic observation of a polished section shows that meteorite consist of coarse grain matrix with nonporphyritic chondrules with unclear boundaries. The matrix minerals are olivine, low-Ca pyroxene, high-Ca pyroxene and plagioclase. Metal and troilite are a little oxidized (weathearing grade W0/1).

Geochemistry: Mineral composition and Geochemistry: EDS analyses (A. Agakhanov, K. Konovalova, FMMR). Olivine 26.42±0.46 (N=20), Low-Ca pyroxene Fs22.8±0.3Wo1.56±0.24 (N=20), high-Ca pyroxene Fs16.8±1.4Wo44.88±0.65 (N=4), plagioclase Ab80.0An12.1Or7.8 (N=6). Composition of kamacite (in wt. %, n = 4): Fe - 90.58, Ni - 7.43, Co - 0.81, taenite (in wt. %, n = 3): Fe - 75.04, 26.11, 0.71

Classification: (K. A. Konovalova, FMMR). Ordinary chondrite. LL6, S1, W0/1.
