(Tatar Republic, Russia) CO3.1 (stone)
Fell 13th September 1937
Kainsaz is an extremely rare Russian carbonaceous chondrite and a witnessed fall in the old USSR back in 1937. Carbonaceous chondrites represent some of the most primitive of all meteorites and are intensely studied. Many small chondrules and a surprising amount of fine nickel-iron metalflake are visible in cut sections of this very rare meteorite.
