Associated transgressive and downlap surfaces coincide with boundaries of biozones. Lowstand systems tracts consist of estuarine and braid delta systems. Transgressive and highstand systems tracts are composed of carbonate banks and reefs. Slow thrust-induced changes of the basin topography conditioned the basic type and the areal distribution of carbonate highstand and clastic lowstand systems. Rapid relative sea level changes controlled the activity and internal dynamic of the depositional systems. E-W directed blind thrust anticlines are covered during highstand periods by carbonate fringing banks withNummulites bars. N-S orientation of thrust anticlines leads to the evolution of reef-dominated barrier banks and shelf lagoonal homoclinal ramps. On-bank transport of carbonate sands dominates during transgressions, off-bank transport during highstand periods. Continuous thrusting during the Ilerdian caused angular unconformities only in combination with relative sea level fall. Sequence-internal onlap configurations result from contemporaneous tectonic tilting. Fourth order carbonate bank margin cycles contain well developed lowstand tracts due to increased subsidence rates. Fourth order flooding surfaces are marked by paleosoil horizons at their landward continuation.
