Omolon - Pallasite, PMG

Omolon is a rare Main Group Pallasite from the Omolon River basin in Magadanskaya Oblast, Russia. A bright fireball was reported by a meteorological station on 16 May 1981, and a 250 kg mass was later found by reindeer-breeder I. Tynavie, who had observed the fall. The meteorite was recovered in June 1990 and is officially classified as a Pallasite, PMG, placing it within the Main Group of Pallasites.

Omolon specimens are composed of iron-nickel metal and olivine, the classic combination that defines Pallasites. Published descriptions report olivine with a composition around Fa12.2 and metal containing approximately 10.6 percent nickel. Cut and polished pieces can show olivine crystals set within a metallic matrix, while natural or less prepared material may display weathered exterior character from its time on Earth.

Studying Omolon provides insight into Pallasite formation, metal-silicate mixing, and the complex history of early differentiated asteroid bodies. Its Russian provenance, reported witnessed fall history, large recovered mass, and Main Group classification make it especially desirable for collectors of Stony-Iron meteorites. Each specimen represents ancient asteroid material preserved as a mixture of metal and olivine, formed over 4.5 billion years ago.
