Abstract
Variations in thickness of mid-Carboniferous strata in the Midland Valley reflect variations in the original pattern of subsidence. This pattern is thought to be deep-seated in origin and probably related to the Variscan orogeny. Variations in sedimentation facies in space and time suggest the operation throughout Carboniferous times of an epeirogenic movement with at least two orogenic episodes. It is suggested that the Carboniferous strata were deposited in a delta-flank depression, the rhythmic character of the succession being due to alternating phases of abundance and scarcity of clastic detritus superimposed on a history of more or less continuous subsidence.
