“…The average direction of the chain axis is about N150°, cor-responding to the strike of the main thrusts and coaxial normal faults. The axial zone of the belt was also affected by strike-slip faults trending, mainly N120°±10° and N 50°-60°a nd by low-angle normal faults (Schiattarella 1998;Schiattarella et al 2003, and references therein) during PliocenePleistocene times, extensional tectonics characterized the Middle Pleistocene to Present time interval (Schiattarella 1998;Giano et al 2000).…”

“…During the Early Pleistocene, the Agri basin developed in response to left-lateral strike-slip N120° trending master faults, reactivated as normal faults after the Middle Pleistocene Schiattarella et al 1998). This tectonic regime is also responsible for the development of many Quaternary intermontane basins of the southern Apennines, even though a more complex structural setting has been suggested for the Agri valley's evolution (Di Niro & Giano 1995;Giano et al 1997;Schiattarella et al 1998;Giano et al 2000;Cello et al 2000). Meso-structural analysis performed on fault planes indicates a recent regime with a NE-SW tensile axis.…”

Abstract:The Agri River high valley is a Quaternary intermontane basin located in southern Italy. The tectonic evolution of this basin was controlled by Lower Pleistocene strike-slip master faults, subsequently reactivated as normal faults until the Middle Pleistocene. The Quaternary sediments of the basin infill are mainly constituted of continental clastics, represented by coarse-grained alluvial deposits divided by unconformities. The arrangement of clastic deposits suggests that the Pleistocene to Holocene alluvial fan system developed along the eastern margin of the valley. Five generations of slope and alluvial fan systems have been recognized in the Agri basin. The oldest fans have formed on both slope and alluvial deposits. The younger alluvial fans are located along the entire valley floor and arose upon the earlier fan apexes originating in these valleys. The youngest fans are arranged in two different generations and show proximal facies distributed along the foot slopes. Plan view morphology, fan slope profiles, and sedimentary features of the fan system have been used here to determine the magnitude of the tectonic deformation episode affecting the faulted mountainous front of the Agri basin eastern margin. Both fast and slow tectonic episodes occurred during the different regional Quaternary tectonic stages that affected the southern Apennine chain. These tectonic episodes have therefore been analysed in relation to climatic conditions in order to determine their contributions to the evolution of the Pleistocene to Holocene fan systems.

“…In particular, at this locality, a N160°E trending fault, showing a left-lateral component can be seen to crosscut a N30°E-oriented fault connected to the formation of the graben. In addition, N160°E trending faults crosscut cemented slope deposits referred to the Early-Middle Pleistocene (Giano et al 2000). This indicates that Pleistocene N160°E trending faults, possibly connected to the formation of the Agri valley, formed after the minor N30°E trending graben.…”

“…These faults are the result of the recent tectonics that has affected the axial sector of the Southern Apennines since the Middle Pleistocene (Giano et al 2000). In more detail, 'Il Monte' is bounded by a series of normal faults, oriented approximately N30°E, controlling the Fig.…”

A Geological Itinerary Through the Southern Apennine Thrust Belt (Basilicata—Southern Italy)

et al. 2015

View full text Add to dashboard Cite

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.
