Osterzgebirge
The Karsdorf Fault ( or "Karsdorfer Verwerfung") is a striking tectonic fracture line, which is part of the Central Saxon Fault, and is located in the eastern Ore Mountains and the Elbe Valley Slate Mountains of Germany. It forms the northern geological boundary of the Eastern Ore Mountains in the district of Sächsische Schweiz-Osterzgebirge with the Elbe zone, where it is adjoined by the Döhlen Basin and the Kreischa Basin.
