Broad saddle
A broad saddle is a geological saddle or dome structure created by halokinesis , in which the outer layers are bulged over a relatively wide and flat salt structure ( salt cushion or low salt dome). The cover layers are therefore relatively shallow, bite out over a large area in the core of the saddle structure and are only slightly disturbed .
A broad saddle manifests itself on the earth's surface, depending on whether the core is erosion-resistant or erosion-prone rocks, either as a wide, gently rising ridge or as a hollow lined with narrow, low ridges. Broad saddles can be found in Germany in large numbers in the northern Harz foreland, such as the Elm , the Große Fallstein , the Oderwald and the Hakel .
The counterpart to the broad saddle is the narrow saddle .
