From: Pliocene to Quaternary deformation in the Var Basin (Nice, SE France) and its interpretation in terms of “slow-active” faulting

Sketch evolutionary model for the activity of the St Blaise-Aspremont and Donaréo fault systems. (1) The Pliocene molasse-type sediments were deposited in submarine conditions after the Messinian crisis at ca. 5.3 Ma. The molasse-infilled incised valleys were formed during the Messinian crisis, and thus sealed the pre-Pliocene deformation. (2) Reactivation of the strike-slip system in Pliocene to Quaternary times resulted in basin axial valley migration to the side of the developing morphology. (3) A significant part of the uplift (a minimum of 100 m) is ascribed to tectonic movements along the faults, which resulted in the Pliocene verticalization
