“…The frontal portion of the Southern Apennines consists of imbricate thrust sheets, made up essentially of Irpinian and Lagonegro units that tectonically overlie the Pliocene-Early Pleistocene foredeep deposits of the Bradanic Trough (Piedilato and Prosser 2005;Palladino 2011). The allochtonous units are thrust over the Plio-Pleistocene sediments along a shallow-dipping surface.…”

The proposed geological itinerary connects a series of impressive outcrops distributed between the front and the inner portion of the Southern Apennine thrust belt. It offers the opportunity to visit some of the most interesting and bestexposed Southern Apennine geosites, inserted within landscapes typical of the different sectors of the thrust belt, in order to illustrate its geological evolution. The itinerary has been designed in such a way as to intersect different stacked tectonic units and a great variety of sedimentary successions whose age ranges from Triassic to Pleistocene. Each of the chosen geosite contains multidisciplinary geological information that may be of interest for researchers, but may be also appreciated by a general public interested in geology. In particular, the stratigraphy, the structural geology and the geomorphology are the most recurrently treated topics. Most of these outcrops extend for many hundreds or thousands of metres and include villages or mountain reliefs. Therefore, every single site can be considered as an areal geosite containing particular geological features. However, the largest geosite can also be observed in a panoramic view from suitable locations. Thus, each of these sites provides different evidence and when combined together provides an opportunity to understand the complex geological history of the Southern Apennines. The motivation for establishing this itinerary mostly resides in the great scientific interest of the chosen outcrops; this will hopefully facilitate their conservation and the development of geotourism.

“…Lucanian Apennines tectono-stratigraphic units are derived from the Afro-Adriatic paleomargin deformation and are tectonically layered as follows: the Liguria-Piedmont Ocean units of the Liguride and Sicilide complex, from Cretaceous to Oligocene; Apennine Platform carbonate units, from Late Triassic to Tertiary; and the Lagonegro Basin units, from late Paleozoic to Tertiary (e.g., Scandone, 1967;Ogniben, 1969;D'Argenio et al, 1975;Mostardini and Merlini, 1986;Carbone et al, 1991;Roure et al, 1991;Monaco et al, 1998;Cello et al, 2000a;Menardi Noguera and Rea, 2000;Lentini et al, 2002;Tavarnelli and Prosser, 2003;Piedilato and Prosser, 2005). Thrust sheet top siliciclastic deposits (e.g., Gorgoglione Flysch) are emplaced by Tertiary upon tectonostratigraphic units indicated above (Carbone et al, 1991;Butler and Tavarnelli, 2006, and references therein).…”

Abstract.A landslide, to the west of Montemurro (a small village in southern Italy), has recently caused damage to buildings and other infrastructure in an urbanized area; as a result the development of new economic activities has been prohibited. The landslide phenomenon started in the last century and has been studied since the 1990s using classical geotechnical methods; however the sliding body continues to move. This paper presents the results of a study carried out using field surveys, geognostic investigations and TDR (time domain reflectometry) measurements in order to reconstruct the stratigraphy of the sediments involved and to further understand the geological and geomorphological context of the slope. This study is part of a larger multidisciplinary project, the results of which will also be presented in this paper. The landslide (rotational slide in the upper sector, developing into a translational slide in the lower part) affects Quaternary continental clastic deposits resting on a bedrock formed by Tertiary siliciclastic sediments of the Gorgoglione Flysch. TDR measurements did not show any significant movement during the period monitored (January 2013-January 2014). Slip zone geometries were hypothesized using inclinometric measurements taken from previous studies, stratigraphic data and geomorphological interpretations of topographic scarps. Feedback from monitoring will confirm this hypothesis.

“…The architecture of the southern Apennines is broadly characterized by two distinct orogenic wedges (e.g. Patacca & Scandone, 2007;Piedilato & Prosser, 2005). The upper and older wedge outcrops forming the relief of the chain; it consists of allocthonous units which represent the Oligocene-Miocene frontal accretion and thin-skinned shortening of palaeogeographical domains belonging both to the Mesozoic -Paleogene divergent margin of the Adria (Apenninic Platform and Lagonegro-Molise Basin) and to the Miocene -Pliocene convergent setting of the Southern Apennine Foredeep; these structural units are imbricated beneath the Liguridi and Sicilidi nappes, a western-traveled structural lid offscraped from the subducting oceanic crust of NeoThetys (Lentini, Carbone, Di Stefano, & Guarnieri, 2002).…”

“…Anticlinal stacks and thrust from the lower wedge (Apulia duplex) punched up into the upper wedge causing complex deformation that propagated toward the foreland as breaching thrust, asymmetric folds and strike slip faults (e.g. Mostardini & Merlini, 1986;Patacca & Scandone, 2007;Piedilato & Prosser, 2005). Middle Pleistocene -Holocene shortening has resulted in the subduction of thicker, more buoyant Adria lithosphere which has driven peninsula-wide regional uplift of the foreland and Apennine wedge (e.g.…”

Morphostructure of the Lucania Apennines front between the Basento and Salandrella rivers (Southern Italy)

We have produced a morphostructural map to explore the tectonic geomorphology of the Lucania part of the southern Apennines mountain front to assess the relative role that tectonic and erosion processes played in shaping the topography of this part of the orogen. Data were collected mainly through field work and airphoto interpretation. The main morpho-tectonic elements seem to be affected by out-of-sequence thrusting and wide regional uplift which played an important role in the latest stage of orogenic wedge evolution.The geomorphic expression of the local tectonics of individual structures reflects the structural and stratigraphic heritage and were overprinted in the Middle Pleistocene when regional rock uplift lifted the entire mountain front and its foredeep above sea level, imparting a new tectonic slope that dictates erosion and landscape evolution to the present day. Distinct geomorphological features such as asymmetrical ridges, relict valleys and paleosurfaces, have developed on rocks of variable durability and are exposed by regional uplift and erosion along non-cylindrical structures, fault transfer zones, and lateral ramps.This map also identifies for the first time a relict strike valley at the mountain front and a set of geomorphic markers that highlight the particular relationship between drainage evolution and thrusting.
