Pallasovka is apallasitemeteorite found in 1990 near the town ofPallasovka,Russia.
One single mass of 198 kilograms (437 lb) was found 27.5 kilometres (17.1 mi) from the town ofPallasovka by N. F. Kharitonov (a local resident) on adike on the edge of an artificialwater reservoir. Thepond and dike were built in 1978 using explosives so the mass has probably been lifted to the surface from a depth of about 2 m.[2] In fall 2004, Kharitonov gave a small sample to A. Ye. Milanovsky who transferred it to the Vernadsky Institute (Moscow) and then proved its meteoritic origin.
The town of Pallasovka was named afterPeter Pallas (1741-1811), a famous naturalist who took part in the discovery and the study of the firstpallasite, a type of stony-ironmeteorite named after him. Coincidentally, Pallasovka is a pallasite meteorite named after a town named after the discoverer of pallasites.
Thispallasite consists of approximately equal parts ofolivine and metal. Some olivine crystals reach a size of 3 centimetres (1.2 in). Its composition is similar to the Main Group pallasites, however it is called anomalous because chromites differ in composition both from that of the Main and Eagle Station pallasite groups.[2]
The main mass has abundant rusty fusion crust with someregmaglypts and was held by an anonymous purchaser.[1]
A 9336 g sample and one polished section are on deposit atVernad.
