Pic of the day #236 (Hinterland dipping Duplex)
Hinterland-dipping duplexes– The general process lies in that the successive thrust faults cut into the foot-wall forming horses. Younger faults tilt the previous fault and the horse back toward the hinterland. New horses do not move beyond the tip of the next successive thrust fault into the foot-wall Displacement is progressively transferred from the faults bounding the duplexes to the floor thrust and the roof thrust is never active as a distinct fault.
