Sandbox experiments with different boundary conditions demonstrate that antiformal stacks result from a forward-breaking thrust sequence. An obstacle blocks forward thrust propagation and transfers the deformation back to the hinterland in a previously formed true duplex. In the hinterland. continued shortening causes faults to merge toward the tectonic transport direction until the o... https://www.roneverhart.com/RME-Fireface-UFX-III-Audio-Interface-p32300/
