“…A crude time-averaged incision rate (approximately corresponding to total uplift) can be thus estimated to be in the range $0.15-0.3 mm/year. This range is comparable with the mean values of uplift rates constrained in the range of 0.1-0.5 mm/year proposed for the Central and Northern Apennines (Alvarez 1999;Coltorti and Pieruccini 2000;Cyr and Granger 2008, and references therein). The comparison with thermochronometry data (indicating post-4.5 Ma long-term exhumation rates of $1.2 mm/year; Zattin et al 2002) would suggest erosion rates close to 1 mm/year, or alternatively that exhumation rates have slowed significantly in the last million year (Cyr and Granger 2008).…”

This work examines the connection between Quaternary tectonics and erosion/incision processes in the primary TuscanRomagna watershed of the Northern Apennines, which essentially coincides with the topographic culmination of the Nero Unit structural ridge. Tectonic and geomorphic information were collected in the area where this ridge is crossed by the upper Tiber River course forming a deep gorge. Structural analysis and field mapping have revealed that the region experienced polyphase tectonics with superposed thrust folding events identifiable both at the map and mesoscopic scales. Hinterland-SSW-verging thrusts and thrust-related folds deformed the whole thrust pile during the latest deformation phase. Backthrusts/backfolds controlled the development of intermountain basins nearby the main watershed during the Early Pleistocene and seemingly deformed, in the Tiber gorge, a low-relief landscape developed in the Early Pleistocene (ca. 1.1 Ma). Successively, the upper Tiber River course area and Apennines axial zone underwent a generalized uplift, which is manifested by the deep incision of palaeo-morphologies. This proposed sequence of events correlates well with the major geodynamic change of the Apennines revealed by an acceleration of uplift rates in the Middle-Late Pleistocene. This latter event may also correlate with increased rates of river incision recorded in Europe as a consequence of uplift and/or climate change.

“…This deformation caused the complex superimposition of the tectonic units one over the other and over synorogenic pelitic arenaceous turbiditic sequences. The consequent tectonic thickening led to the emersion of the chain and the shaping of the incipient landscape composed of low hilly relief, gentle surfaces and islands, bordered by bays and small marine basins (Coltorti & Pieruccini 2000;Parotto et al 2004;APAT 2006 a,b,c,d;Patacca et al 2008;ISPRA 2010 a,b,c,d;Vezzani et al 2010;Calamita et al 2012;Miccadei et al 2012 a;Bonini et al 2014 and references therein). Compressional deformation was followed by strikeslip tectonics along mostly NW-SE to NNW-SSE-oriented faults poorly constrained in age and largely masked by later extensional tectonic events.…”

Abstract:The most recent research studies into the long-term landscape evolution of the Abruzzo area, carried out over the last twenty years at the "G. d'Annunzio" University of Chieti-Pescara, are based on an integrated approach incorporating structural geology and geomorphology and, in particular, the geomorphometry of topographic and hydrographic aspects, geological and structural-geomorphological surveys and mapping supported by morpho-stratigraphic and chrono logical constraints.The geomorphological analyses have allowed us to outline the main stages of geomorphological evolution and to identify the factors that have contributed to the landscape shaping of the Apennine Chain, the Adriatic Piedmont and the fluvial plains and coastal sectors, up to the Tremiti islands. In the Apennine Chain, landscape evolution -in a ridge, valley and basin system -is connected to the regional uplift, local tectonic subsidence and local base level variations, which have led to changes in the drainage systems, from exoreic to endorheic (in the intermontane basins) and then to exoreic again. In the Adriatic Piedmont, landscape shaping is connected to uplifting and eustatic sea-level fluctuations, which have induced the formation of a structure-controlled drainage system and the shaping of systems of entrenched alluvial fans and large consequent river valleys, with flights of river terraces. In the coastal Adriatic area -composed of a coastal plain-coastal slope system (northern and southern coast) and of a cliffed rocky coast (central coast, Tremiti) interrupted by river valleys -landscape shaping is the result of selective erosion due to the interaction between marine geomorphic processes and slope processes connected to Late Quaternary eustatic fluctuations.

“…For the Apennines that are one of the youngest mountain chains in the world, these approaches have been successfully applied in several sectors of the central and southern Apennines (Brancaccio et al 1979(Brancaccio et al , 1988(Brancaccio et al , 2000Bosi et al 1996;Amato & Cinque 1999;Coltorti & Pieruccini 2000;Bartolini et al 2003;D'Alessandro et al 2003;Schiattarella et al 2003Schiattarella et al , 2006Coltorti et al 2005;Di Bucci et al 2005;Aucelli et al 2011;Amato et al 2014;Gioia et al 2014). With particular reference to the Molise sector of the Apennines, several studies have been conducted and published by our research group (Aucelli et al 2001(Aucelli et al , 2012Russo Ermolli et al 2010;Amato et al 2011Amato et al , 2012Amato et al , 2013Amato et al , 2014Bracone et al 2012a), while others are still in progress.…”

This paper concerns the reconstruction of the main stages of the long-term landscape evolution of the Molise portion of the central-southern Apennines along a transect divided into three sectors (SW, Central and NE). Analysis mainly focused on geomorphological, stratigraphical and structural data supported by chronological constraints, coming from an overall review of past literature and several studies carried out by the authors of the paper during the last 20 years. The results obtained allowed the elaboration of a conceptual model of the long-term evolution of the Molise sector of the central-southern Apennines. Starting from the Pliocene, the emersion of the Molise area occurred gradually from SW to NE, allowing a polycyclic landscape to evolve under the major controls first of compression then transtensional to extensional tectonics as well as climatic variations. Principal markers of the Quaternary geomorphological evolution of the Molise area are represented by the infill successions of the intermontane tectonic depressions located in its internal, SW sector and by four orders of palaeosurfaces that developed between the Early Pleistocene and the beginning of the Late Pleistocene across the region. These markers testify to the alternation of phases of substantial tectonic stability and uplift whose spatial-temporal distribution could be assessed along the investigated transect. Results highlight that the most important stages of landscape evolution occurred during the Early and Middle Pleistocene. At the beginning of the Late Pleistocene, the Molise sector of the Apennine chain had already reached its present setting and further landscape evolution occurred under the major control of climate and land-use.
