Bear rockWe regularly share interesting shaped rock formations formed by erosion. This granite work
Bear rockWe regularly share interesting shaped rock formations formed by erosion. This granite work of nature’s art is located in Sardinia. The type of structure is called Tafoni, or honeycomb structure, and results from water leaching dissolved minerals to the rock surface. As it dries the minerals precipitate and flake off layers of rock in a process called cavernous weathering. The shape of the formation therefore reflects the movement of fluids through the granite.LozImage credit: Martin Wintsch -- source link
