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 consequence
of the interplay between the rates of base-level rise and of
local sediment supply in adjacent areas. Moreover, variations of
depositional trends of local significance can also be recorded by
