Aumakivi is a tor corestone. It is a piece of granitic bedrock that has been preserved after surrounding rocks have disintegrated due to weathering. The weathering process is particularly strong in hot and humid climate. Finland enjoyed such a climate just several tens of millions of years ago. The granite of Aumakivi is 1900 million years old and the formation of the tor happened some 70 to 20 million years ago.
