Maslyanino meteorite - IAB iron meteorite from Russia The Maslyanino meteorite was found on May 25, 1992, by agronomist V. G. Okel in a field near the village of Maslyanino in the Novosibirsk region, Western Siberia. The main mass weighing approximately 26 kg is the only recorded specimen. Classification It is an iron meteorite of the so-called IAB complex, specifically a fine octahedrite with a metallic matrix and the presence of silicate inclusions. Maslyanino contains 12.4 % nickel and trace elements such as germanium, gallium, and iridium. The matrix consists of metallic phases – kamacite and taenite – with a well-developed Widmanstätten pattern, as well as sulfide phases (troilite) and various silicate inclusions such as olivine, pyroxenes, plagioclase, and graphite. Scientific significance Maslyanino is particularly interesting because of the presence of silicate inclusions within an iron meteorite – a relatively rare phenomenon typical of the IAB meteorites. Analyses have shown that its mineral composition corresponds to a subgroup similar to the Pitts meteorite, representing slow cooling processes characteristic of a differentiated planetesimal core. Sample location The main mass of the meteorite is preserved at the Geological Museum of the Institute of Geology and Geophysics, Siberian Branch of the Russian Academy of Sciences in Novosibirsk.
