A three-dimensional (3-D) visualization technique is used to build a structural model linking a complex series of thrust sheets in an external area of the northern Apennines, central Italy. This foreland fold and thrust belt consists of faulted anticlines and broad synclines, involving a Triassic-Paleogene succession that is detached from the underlying basement. Reactivation of basement faults has influenced the geometry and kinematics of the overlying structures in a mix of thin-skinned and thick-skinned tectonics. Upper detachment horizons within the sedimentary succession form shallow structures in the crestal zone of the major anticlines. All the structures are scantily cylindrical, and the model demonstrates the soft linkages between oblique and frontal structures through relay ramps.
