“…In the growing fold and thrust belt, the simultaneous development of thrusts, backthrusts, and lateral displacement and the occurrence of clockwise nappe rotations [44][45][46] during Late Miocene -Early to Middle Pleistocene, create morphostructural depressions filled by syntectonic deposits during a continuous forward migration. In this regional context, the TRV which crops out in the study area has been interpreted as the sedimentary record of the inner portion (wedge-top depozone sensu [11]) of the Late Miocene (Tortonian-Messinian) (SFBS, [1,3]). TRV was unconformably deposited above already deformed units characterizing two "end member"units, named [2,3] inner (IWS) and outer (OWS) wedge-top sequence, respectively (Fig.…”

Detailed field sedimentological and facies analyses have been performed in the Terravecchia Formation cropping out in NW Sicily, in order to differentiate and describe, for the first time, wave-and river-dominated shallow-marine (deltaic) siliciclastic successions. The latter were deposited filling syntectonic basins, developed between the late Tortonian and early Messinian time, within the wedge-top depozone of the Sicilian Foreland Basin System. It has been observed that river-dominated successions, recording the deposition of small fan-deltas are characterized by fining-to coarsening upward, transgressive-regressive sequences which were mostly deposited filling relatively narrow and often oversupplied basins. These basins were probably located in a proximal sector of the wedge-top depozone, closer to emergent sectors of the chain and probably sheltered from the main marine areas. Wavedominated successions, on the other hand, are characterized by upward fining, mostly transgressive sequences which were deposited filling wider basins open to major marine regions and located in a more distal position of the wedge-top depozone. The documented partitioning between river-and wave-dominated successions, as a function of the position of the sedimentary basin within the wedge-top depozone, is coherent with data from analyses of the deformational patterns of the Terravecchia Formation in this study area. Furthermore, the data here presented could be considered as a preliminary database for future characterization and analysis of siliciclastic reservoirs from Sicilian outcrop analogues.
