Carbonaceous chondrite (CO3.2; S1; W0)
Observed fall, 13 September 1937; 15 stones, mass ~ 200 kg.

Kainsaz is the most massive CO Chondrite and, as such, has provided material for a number of studies. Studies of some high temperature Ca & Al rich inclusions (CAIs) formed at high temperatures during the very early epochs of the Solar System have been of continuing interest. In the last two decades, studies of small diamonds, silicon carbide, and other exotic presolar components have also begun to appear.
