Description :
Valleys formation was controlled by a complicate temporal and spatial pattern of the earthcrust movements (both of glaciaoisostatic and tectonic origin); by frequent changes in local base levels formed by meltwater proglacial lakes; by changes in the World Ocean level which opened and closed intermittently the connection with ancient Baltic basins the latter were a base level for Baltic rivers during the finiglacial and postglacial time); a certain effect on the valleys formation had changed in rivers discharge after ten water supply form the ice sheet had been stopped and proglacial lakes drained. Three cycles of active terrace formation are distinguished : (Pre-Alleröd, Alleröd-Boreal and middle and late Holocene. - (D'après l'A.).
