Rollover anticlines are fault related anticlines.

Examples of these fault related anticlines can be found over the Mardin High in southeast Turkey. It is an anticlinal feature that has as steeply dipping south limb, while the north flank is gently dipping. This anticline is directly above the town of Mardin, hence where it gets its name. Cretaceous aged sediments dominate the surface geology of the Mardin Structure, and its western limits are slightly past the point where Midyat Limestone dominates the surface.
