The history of the AB filling described above can be linked to a general model of the factors controlling the sedimentary filling of semi-enclosed basins. The sedimentary succession bibr1532 dependent on the available accommodation space. In semi-enclosed basins, accommodation space is controlled by the fluctuations of sea level, the bedrock morphology, the vertical movements of the basin floor through subsidence or uplift, and the sedimentation rate (Van Daele et al., 2011). Sedimentation is intimately linked to environmental and climatic conditions, and thus provides information and chronological references of sea-level changes (Torgersen et al., 198 cool . The bedrock topography (i.e. the paleo-seafloor) is the major forcing parameter in determining accommodation space. The position and depth of the sills determined the topographic threshold above which sea-level rise will induce the flooding of the basin. During lowstands and the early post-glacial transgression, a lacustrine phase is polar covalent bond thought to have taken place, with different features (Reeves et al., 2007 and Çagatay et al., 2009). The sea-level rise induced a progressive flooding of the basin, which resulted in the formation of an erosion surface (Perissoratis et al., 2000 and Lericolais et al., 2009). Depending on fluvial activities and tidal range creating tidal channels, an estuarine or lagoonal sedimentation occurred (Reeves et al., 2007). Finally the sea-level highstand led to a shallow marine environment. Then a marine sedimentation took place, expressing various dynamic conditions related to the distribution, nature, and bathymetry of the shoals (Torgersen et al., 1988, Reeves et al., 2007, Barboza et al., 2009 and Van Daele et al., 2011), and to the presence of the coastline at the edge of the basin.
