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

Block diagram derived from 3D-geological modelling using the BRGM software developed with the methods of Lajaunie et al. (1997). The 3D model illustrates the relationship of basin formation and strike-slip faulting along the western margin of the Nice Arc. Two superposed (Pliocene marine and Plio-Quaternary lacustrine) basins are emplaced along the fault runoff. Double unconformity is shown by relatively flat-lying Plio-Quaternary basin, tilted by about 40° above verticalized Pliocene molasse sealing the Messinian topography. These relationships are in agreement with basin migration during topographic building along the Mont Cima-Les Salettes mountains. In turn, topographic building is geometrically related to the location of the fault along the Mont Cima
