Abstract. Thrust propagation through previously faulted continental margins may result in fold and thrust belts whose structure is strongly controlled by the inherited basin architecture. A detailed geological study has been carried out in the external zone of the Umbria-Marche Apennines, from Monte San Vicino to the north, to Montagna dei Fiori to the south. Stratigraphic and structural data, together with the construction of a series of balanced and restored geological sections, point out the fundamental role played by the preorogenic basin architecture in controlling the geometry and evolution of the fold and thrust belt. Pre-thrusting structures include not only those inherited from the Mesozoic rifted continental margin, but also synsedimentary faults associated with Miocene extension which occurred ahead of the advancing thrust front. The latter structures produced important facies and thickness variations in the units deposited during the late Burdigalian-early Messinian, pre-evaporitic stages of foredeep development. In the southern sector (Montagna dei Fiori), high values of Messinian regional subsidence, bathymetry and sedimentation rate overcome the effects of synsedimentary extensional tectonics, which is best recorded in pre-Messinian sequences. On the other hand, Messinian regional subsidence was significantly less in the northern sector (Monte San Vicino). Here, several minor sub-basins developed within the foredeep, generally reaching evaporitic conditions during the middle Messinian (marked by the deposition of the Gessoso-solfifera Fm). In this area, a major control by pre-thrusting normal faults on sedimentation is recorded in the foredeep siliciclastic sequences. Late Burdigalian-early Messinian extension, possibly associated with flexure of the foreland lithosphere, peripheral bulge uplift and/or foreland tectonic activity, was followed by a late Messinian (post-evaporitic) contractional episode of regional extent. During shortening, inversion of preexisting MioceneCorrespondence to: S. Mazzoli (s.mazzoli@geo.uniurb.it) extensional structures was quite limited. Hanging wall basin fills were retained and pre-thrusting faults show very limited or no reversal of slip. However, these faults and their hanging wall basin fills are generally deformed by buttressing phenomena, and fault planes are often tilted and/or locally reactivated in strike-slip. The present-day structure is dominated by newly-formed thrusts that cut across the preexisting extensional architecture, which is in general quite well preserved within different thrust sheets.

“…Barchi et al, 1998). However, the notion that some fold-thrust structures in the Apennines might not conform to the simple fault-bend relationships developed by compression acting on a layer cake stratigraphy has been questioned recently.…”

“…The tectonic Ligurian and Tuscan nappe stack in the northern Appennine is unconformably overlain by Eocene to Pliocene Epiligurian units, deposited in marine thrust-top piggyback basins (Ricci Lucchi 1986;Barchi et al 2001;Cibin et al 2001). Epiligurian units, which outcrop in the central-northern part of the investigated area, consist, from bottom to the top, of Bismantova formation (Lower-Middle Miocene), Ranzano sandstones (Oligocene) and Loiano sandstones (Lower Miocene), and are mostly made of siliciclastic and bioclastic marly-silty sediments, alternating with pelitic-arenaceous and arenaceous bodies, calcarenites and sandstones (Bettelli et al 2002).…”

This paper illustrates the contribution of Persistent Scatterer SAR Interferometry (PSInSAR) technique to landslide detection, using interferometric data acquired in C-band by European remote-sensing satellite (ERS) 1/2 and environmental satellite (ENVISAT) satellites. The main purpose is to update a pre-existing landslide inventory map, by changing or confirming the landslide geometry and state of activity and eventually, identifying new phenomena.This work presents an application of satellite remote sensing to analyse ground displacement movements in the Setta basin, located on the northern Appennine (Bologna province, Italy) and extended up 268 km 2 .The proposed methodology, resting upon pre-existing works already consolidated in the scientific community, combines interferometric measures with aerial imagery and other auxiliary data, in order to detect landslide indicators, finally validated with field surveys. The use of an activity matrix allows the identification of the state of activity of landslide phenomena with respect to the velocity of the radar displacement rates. Field validations are carried out in the areas that are more relevant because of the highest ground velocities and the presence of structures extensively affected by ground movements.The final updated landslide database of the Setta basin, based on Persistent Scatterer Interferometry analysis and in situ checks, consists of 1550 landslides, 236 of which have persistent scatterer information.
