“…The integrated analyses performed here highlight that tectonics played a key role in the basin's genesis and evolution (Turco et al 1991;Cifelli et al 2007;Tansi et al 2007). The reconstructed geomorphological and sedimentary history shows that the study area experienced a number of morphogenetic cycles since the Pliocene (Piacenzian?)…”

“…Their evolution has been controlled by a series of roughly NW-and WNW-trending strikeslip fault zones formed during the Neogene. They controlled the migration of the Calabrian Arc and experienced episodes of extension (Van Dijk et al 2000), responsible for the dissection of the Calabrian Arc (Lanzafame & Zuffa 1976;Lanzafame & Tortorici 1981;Tortorici 1981; Knott & Turco 1988;Turco et al 1990;Tortorici et al 1995;Schiattarella 1998;Cifelli et al 2006;Tansi et al 2007). This resulted in an alternation of morphostructural ridges and Plio-Quaternary tectonic depressions bounded by high-angle fault scarps (Fabbri et al 1981;Barone et al 1982;Argani & Trincardi 1993;De Rosa et al 2002;Milia et al 2008;Filocamo et al 2009;Robustelli et al 2005Robustelli et al , 2009Pepe et al 2010;Spina et al 2011;Tripodi et al 2013;Longhitano et al 2014;Robustelli et al 2014;Zecchin et al 2015).…”

Abstract:In this paper, we present the results of an integrated geomorphological and stratigraphical study carried out in the eastern side of the Crati River valley (northern Calabria, South Italy). This area is characterized by the occurrence of three order palaeosurfaces that, along with low-sloping palaeovalleys and structural landforms, are striking features of the landscape. The relationships between morpho-tectonic and sedimentary evolution of the Crati Basin has been assessed through sandstone detrital modes, morphostratigraphy and geomorphological correlation with adjacent areas. The two main unconformity surfaces that typify the Quaternary fill were correlated to different steps of landscape evolution. The presence of both erosional and depositional palaeosurfaces has been a useful marker for reconstructing sedimentary and morphogenetic events, and hence to detect drainage network evolution and changes in source sediment area. In particular, we recognized that the study area experienced, during the late Pliocene-Early Pleistocene a period of subaerial landscape modelling as suggested by low-sloping palaeovalleys and related fluvial deposits (1 st Order Palaeosurface). At that time, the source of the detrital constituents of the PPS Unit sandstones was mainly from the Sila Massif. The onset of Coastal Range identification and uplift (Early Pleistocene) marks a change in the geomorphic scenario with tectonic driven stream incision and valley development along the eastern side of Coastal Range, along with the occurrence of depositional and erosional landsurfaces (2 nd Order Palaeosurface) at footslopes. During this period, the Coastal Range and Sila Massif were the sources for the detrital constituents of the PlS Unit sandstones. The progressive uplift of Coastal Range during late Early Pleistocene and the marked backstepping of the depositional systems along the Sila footslope was accompanied by alternating phases of down-cutting and base-level stability resulting in the development of a step-like distributed 3 rd Order Palaeosurface. The presence of dolostone in detrital modes is clear evidence of stream piracy phenomena of ancient palaeovalleys by the Crati valley-facing drainage network.

Deformed Pleistocene marine terraces along the Ionian Sea margin of southern Italy: Unveiling blind fault‐related folds contribution to coastal uplift

et al. 2013

Morphotectonic analysis and fault numeric modeling of uplifted marine terraces along the Ionian Sea coast of the Southern Apennines allowed us to place quantitative constraints on middle Pleistocene‐Holocene deformation. Ten terrace orders uplifted to as much as +660 m were mapped along ~80 km of the Taranto Gulf coastline. The shorelines document both a regional and a local, fault‐induced contribution to uplift. The intermingling between the two deformation sources is attested by three 10 km scale undulations superimposed on a 100 km scale northeastward tilt. The undulations spatially coincide with the trace of NW‐SE striking transpressional faults that affected the coastal range during the early Pleistocene. To test whether fault activity continued to the present, we modeled the differential uplift of marine terraces as progressive elastic displacement above blind oblique‐thrust ramps seated beneath the coast. Through an iterative and mathematically based procedure, we defined the best geometric and kinematic fault parameters as well as the number and position of fault segments. Fault numerical models predict two fault‐propagation folds cored by blind thrusts with slip rates ranging from 0.5 to 0.7 mm/yr and capable of generating an earthquake with a maximum moment magnitude of 5.9–6.3. Notably, we find that the locus of predominant activity has repeatedly shifted between the two fault systems during time and that slip rates on each fault have temporally changed. It is not clear if the active deformation is seismogenic or dominated by aseismic creep; however, the modeled faults are embedded in an offshore transpressional belt that may have sourced historical earthquakes.
