“…They developed firstly during the Upper Triassic at the same time as the rifting in Central Atlantic (Leleu et al, 2016;Olsen, 1997;Withjack et al, 1998 and references therein) and in the Alpine domain (Bertotti et al, 1993). Then, whereas slow oceanic accretion or mantle exhumation began in the Central Atlantic (Labails, 2007;Sibuet et al, 2012), they recorded a new rifting phase in the Lower Jurassic.…”

-The Tell-Rif (Tell in Algeria and Tunisia; Rif in Morocco) is the orogenic system fringing to the south the West Mediterranean basins. This system comprises three major tectonic-palaeogeographic zones from north to south: (1) the internal zones (AlKaPeCa for Alboran, Kabylies, Peloritan, Calabria) originating from the former northern European margin of the Maghrebian Tethys, (2) the "Flyschs zone" regarded as the former cover of the oceanic domain and (3) the external zones, forming the former southern Maghrebian Tethys margin more or less inverted. The Tell-Rif is interpreted as the direct result of the progressive closure of the Maghrebian Tethys until the collision between AlKaPeCa and Africa and, subsequently, the propagation of the deformation within Africa. This gives a consistent explanation for the offshore Neogene geodynamics and most authors share this simple scenario. Nevertheless, the current geodynamic models do not completely integrate the Tell-Rif geology. Based on the analysis of surface and sub-surface data, we propose a reappraisal of its present-day geometry in terms of geodynamic evolution. We highlight its non-cylindrical nature resulting from both the Mesozoic inheritance and the conditions of the tectonic inversion. During the Early Jurassic, we emphasize the development of NE-SW basins preceding the establishment of an E-W transform corridor connecting the Central Atlantic Ocean with the Ligurian Tethys. The Maghrebian Tethys developed just after, as the result of the Late Jurassic-Early Cretaceous left-lateral spreading between Africa and Iberia. By the Late Cretaceous, the occurrence of several tectonic events is related to the progressive convergence convergence between the two continents. A major pre-Oligocene (pre-35 Ma) compressional event is recorded in the Tell-Rif system. The existence of HP-LT metamorphic rocks associated with fragments of mantle in the External Metamorphic Massifs of the Eastern Rif and Western Tell shows that, at that time, the western part of the North-African margin was involved in a subduction below a deep basin belonging to the Maghrebian Tethys. At the same time, the closure of the West Ligurian Tethys through east-verging subduction led to a shift of the subduction, which jumped to the other side of AlKaPeCa involving both East Ligurian and Maghrebian Tethys. Slab rollback led to the development of the Oligo-Miocene back-arc basins of the West-Mediterranean, reworking the previous West Ligurian Tethys suture. The docking of AlKaPeCa against Africa occurred during the Late Burdigalian (17 Ma). Subsequently, the slab tearing triggered westward and eastward lateral movements that are responsible for the formation of the Gibraltar and Tyrrhenian Arcs respectively. The exhumation of the External Metamorphic Massifs occurred through tectonic underplating during the westward translation of the Alboran Domain. It resulted in the formation of both foredeep and wedge-top basins younger and younger westward. The lack of these elements in the eastern part ...

“…The complexity of Piemonte geology is the result of a continuous geodynamic process which, since the Rhaetian-Hettangian, led to the formation of two continental 'passive' margins: the 'Palaeo-European Margin' and the 'Palaeo-Adriatic Margin', and two oceanic zones: the Liguria-Piemonte Domain and the Valais Domain (Bernoulli & Jenkins, 2009;Bertotti, Picotti, Bernoulli, & Castellarin, 1993;Dal Piaz, 1974;1999;Dal Piaz, Bistacchi, & Massironi, 2003;Dal Piaz, Hunziker, & Martinotti, 1972;Dewey & Bird, 1970;Dewey, Pitman, Ryan, & Bonnin, 1973;Handy, Schmid, Bousquet, Kissling, & Bernoulli, 2010;Mohn, Manatschal, Müntener, Beltrando, & Masini, 2010;Sturani, 1975;Trumpy, 2001). Since the Late Cretaceous, the European and Adriatic continental plate margins began to converge (Le Pichon, 1968) inducing the subduction of the interposed oceanic lithosphere.…”

The geological map of Piemonte Region (Italy) is a graphic representation of the geology of the region, grounded on a large geodatabase, that can be also browsed as an interactive scalable map (GeoPiemonte Map) using a WebGIS application. The Map, produced at 1:250,000 scale, is the first original release of the 'GeoPiemonte Map' project. The geological data represented on the map derive from a thorough revision of available geological maps and literature, integrated with unpublished original data. The revision and harmonisation of existing and new data have been based on explicit criteria used for the classification of geologic units and their representation on the Map. These criteria firstly aimed at providing a lithostratigraphic, hierarchic subdivision of Piemonte geologic units and describing them using shared concepts and vocabularies, consistent with IUGS Descriptive Standards for the Geosciences.

“…This configuration was controlled by extensional faulting linked to a Norian-Lias rifting phase which led to the opening of the Mesozoic Tethyan basin (Winterer and Bosellini, 1981;Doglioni, 1987;Bertotti et al, 1993;Bernoulli, 2001;Fantoni and Franciosi, 2010). Several authors have suggested that Adria was a promontory of the African plate (Staub, 1951;Dercourt, 1972;Channell and Horvath, 1976) while others consider it as an independent microplate (Dewey and Burke, 1973;Makris, 1981;Finetti, 1982Finetti, , 2005Dercourt et al, 1986;Dercourt, 2000;Stampfli and Mosar, 1999).…”

-The Southern Adriatic Sea is one of the five prospective areas for CO 2 storage being evaluated under the three year (FP7) European SiteChar project dedicated to the characterization of European CO 2 storage sites. The potential reservoir for CO 2 storage is represented by a carbonate formation, the wackstones and packstones of the Scaglia Formation (Upper CretaceousPaleogene). In this paper, we present the geological characterization and the 3D modeling that led to the identification of three sites, named Grazia, Rovesti and Grifone, where the Scaglia Formation, with an average thickness of 50 m, reveals good petrophysical characteristics and is overlain by an up to 1 200 thick caprock. The vicinity of the selected sites to the Enel -Federico II power plant (one of the major Italian CO 2 emittor) where a pilot plant for CO 2 capture has been already started in April 2010, represents a good opportunity to launch the first Carbon Capture and Storage (CCS) pilot project in Italy and to apply this technology at industrial level, strongly contributing at the same time at reducing the national CO 2 emissions.Re´sume´-Le sud de l'Adriatique, un secteur potentiel pour le stockage du CO 2 -Le sud de la mer Adriatique est l'un des cinq secteurs a`avoir e´te´e´value´pour le stockage du CO 2 dans le cadre du projet europe´en FP7 SiteChar qui a dure´trois ans.
