A 160 m thick Pliocene-Pleistocene sedimentary succession, cropping out in NE Sicily (Rometta Succession), was subdivided into three unconformity-bounded units, overlying deformed bedrock: (i) a Middle Pliocene sandy-marly R₁ unit; (ii) an Upper Pliocene-Lower Pleistocene biocalcarenitic R₂ unit; (iii) a Middle Pleistocene mudstone R₃ unit. The R₂ unit is composed of at least three sub-units, bounded by truncation surfaces, and showing aggradational patterns of strata. Each of these sub-units records a sudden seaward-shifting of the facies tract. A stratigraphic gap of ~870 kyr at the R₁/R₂ boundary, marks an abrupt change from offshore transition to shoreface environments. A second gap of ~260 kyr at the R₂/R₃ boundary corresponds to a sudden deepening of the environments, from shoreface to fully offshore. The Rometta units represent three incomplete, tectonically-enhanced depositional sequences. The R₁ unit is a HST of a lower sequence, marked at the top by a slightly angular unconformity. The R₂ unit is a HST of a younger depositional sequence, aggrading above a ravinement surface. During these relative sea level still-stands, the local tectonic uplift combined with the high-frequency eustatic oscillations, produced three forward-stepping sets of minor sequences within the R₂ HST, simulating the typical FSST stratigraphic arrangement. The top of the R₂ is bounded by an erosive surface, representing the transgressive surface of the subsequent R₃ depositional sequence. The R₃ unit is a late TST+HST of a Pliocene-Pleistocene sequence, the LST of which probably occurs basinward. The foresetted R₂ biocalcarenites are unimodal in their paleocurrents. This feature resulted from shore-directed wind stress, applied to the water surface and reflected by a steep paleocoast, generating basinward-directed bottom currents.
