Pallasite
In 1772, Pallas was shown a 680 kilogram lump of metal which had been found near the city of Krasnoyarsk. Pallas arranged for it to be transported back to St Petersburg. Subsequent analysis of the metal showed that it was a new type of stony-iron meteorite. This new type of meteorite was called Pallasite after him, whereas the meteorite itself is named Krasnojarsk or sometimes also called Pallas Iron (the name given to it by Ernst Chladni in 1794).
