Slättemossa Klotdiorit

Spheroidal diorite is a rare rock that solidified at great depths and then came to the surface in folds in the Earth's crust.

There are two visible mountains here, both smaller than 20 square meters. They consist of diorite balls covered with one or more layers of soda ash and hornblende. The space between the balls is filled with granite mass. When the ice sheet ground the mountains, a cross-section of the balls became visible.
