We must make the distinction between pre-orogenic deformation and orogenic deformation of sedimentary basins because there is a great deal of evidence that important deformation occurs in sedimentary basins while they are accumulating sediment on a subsiding sedimentary column — particularly in the terminal regressive sequence. The regressive sequence itself is due to a neighbouring orogeny outside the sedimentary basin: the creation of mountains creates sediment in increasing amounts until the supply of sediment to a sedimentary basin exceeds the volume created by subsidence of the sedimentary basin. The sea then tends to become shallower, and the sediments prograde away from the orogeny.
