  • Greifensteine - Wikipedia

    en.wikipedia.org/wiki/Greifensteine Geology. Geologically, the Greifensteine is the top of a pluton.During the Variscan orogeny, magma intruded along structural zones, but cooled and solidified before reaching the earth surface. When the Erzgebirge block raised, the resulting granite formation raised with it. The surrounding softer material eroded and the harder granite remained, creating the tors of the rock formation.
