History
One single mass of 198 kilograms (437 lb) was found 27.5 kilometres (17.1 mi) from the town of
Pallasovka and Peter Pallas
The town of Pallasovka was named after Peter Pallas (1741-1811), a famous naturalist who took part in the discovery and the study of the first pallasite, a type of stony-iron meteorite named after him. Coincidentally, Pallasovka is a pallasite meteorite named after a town named after the discoverer of pallasites.
Composition and classification
This pallasite consists of approximately equal parts of olivine 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]
Specimens
The main mass has abundant rusty fusion crust with some
A 9336 g sample and one polished section are on deposit at Vernad.
