EVAPORITE STRATIGRAPHY OF THE FRENCH TRIASSIC BASINS - EXAMPLE OF CARNIAN SERIES DEPOSITIONAL SEQUENCES AND THEIR MORPHO-STRUCTURAL EVOLUTION

A review of current dating information on French Triassic basins indic ates that major evaporitic episods occurred at remarkably similar time s throughout Peritethyan basins. More recent studies based on sequence stratigraphy analysis allow to establish the depositional sequence ge ometry of evaporitic series and their clastic and carbonate equivalent s. From examples taken on the evaporitic Carnian series of French basi ns, it is possible to point out local tectonical events. These events control evaporitic sedimentation and may have a more extended origin a t the scale of the West European craton.
