The limestone area rises from the lower surfaces on the Wupperknie near Hammerstein (height at 130 m), which consist of gravel deposits , to the north in stages to high limestone plateaus that reach up to 200 m in height. These limestone plateaus are divided into individual plateaus by side valleys and dry valleys . Further north and south, steep slopes rise to high ridges and plateaus, which consist of greywacke and slate . In the east, the Nützenberger Querriegel delimits the Sonnborn limestone area from the Elberfeld limestone basin . In the west the limestone area merges into the Vohwinkel depression .
In the limestone area there are numerous sinkholes , which are filled with Middle Miocene sands .
