I dont know. Unfortunately, I do not know much about stones. Usually there are granite boulders, but this stone is not granite. Although it is also sturdy (I worked with similar stones, only small ones, the structures of which are quite durable, these stones do not crumble from dampness and temperature changes).
I have long wanted to go to the store and buy a good encyclopedia of local stones, birds and plants, but I'm too busy all the time...
The terrain here is relatively hilly, but there are no mountains at all. At the same time here periodically find these stones. Usually they are dug and put somewhere near the road like a decoration.
Sometimes they are used for building foundations of private houses.
Sometimes any mayor put the stone in the center of a town and write something on them ))
Geologists argue that these stones are from the time of the Ice Age.
Sometimes people dig wells and meet such a stone in the mine, and the whole problem begins.
