Geologically the massif consists mainly of
granite. The history of its
orogeny begins in the
Precambrian about 750–800 million years ago – almost 20% of the
earth's history. Only a few of these mountain stump ranges (
Rumpfgebirge) remain today. File:Kristalle waldstein 002.JPG|Crystal from the Waldstein File:Kristalle waldstein 010.JPG|
