The Oderwald is a salt structure, such as the Elm, the Aces or the Harly. Rock salt has moved upwards because of its lower density compared to limestone, sand and clay stones and has bulged the superimposed layers. As a result, sedimentary rocks from greater depths at the earth’s surface are open to the surface. In the Oderwald, which is only flat, the rocks of the Cretaceous period have reached the surface.
