This study demonstrates that systems tracts composing
sequences can be found in fully back-barrier successions that do
not include the shoreline, and therefore, they can be documented
also where shoreline transgressions and regressions cannot be
directly recognized. As shown across the surface S2, different
depositional trends can be expressed by the abrupt superposition
of distinct generations of tidal channels and tidal and subtidal
flats, reflecting local physiographic changes that are the consequencehydrodynamic changes in adjacent areas, as testified by the surface
S3 that reflects a local transgressive episode affecting the
southern lagoon. Finally, the persistence of a back-barrier environment
during highstand conditions also favored the development
of surfaces that are more characteristic of transgressive
phases, such as TRSs related to tidal currents.

depositional trends of local significance can also be recorded by
