a: Sketch map of the paleoenvironments in the Guzargues basin, in relation with the Priabonian tectonics. b: Conceptual tridimensional representation (no scale intended) of the interaction between Priabonian kinematics and sedimentation in the Guzargues basin. Braided fluvial conglomerates accumulate in the most subsiding parts, i.e. the actively deforming synclines that affect the Mesozoic-Lutetian cover, detached over the basement. See text for explanations.
