“…In the Ligurian Briançonnais area Cortesogno et al (1988Cortesogno et al ( , 1992Cortesogno et al ( , 1993 report that a first period of ignimbrites, tuffs, ashes and lavas of intermediate, mainly trachyandesitic composition for the Latest Carboniferous was followed, during the Early Permian, by a calc-alkaline series of pyroclastites, ashes, ignimbrites and rhyolites. Comparable volcanites of middle Permian age are known in the southern Alps (Pichler 1959) and in southern Europe in general (Cassinis et al 1988(Cassinis et al , 1995, and a comparable magmatic evolution is observed in Corsica (Fumey-Humbert et al 1986;Bonin 1990;Ménot and Orsini 1990;Thevoux-Chabuel et al 1995).…”

“…Upper Carboniferous and lower Permian non-marine sediments comprise sequences deposited by braided, anastomosing and meandering river systems with coal measures and, towards the Permian, playa lakes, formation of caliche and, finally, alluvial fans. This holds for the Saar-Nahe trough (Schäfer 1989), the French Massif Central and neighbouring areas, the northern region of Switzerland (Matter 1987), the Alpine External massifs (Franks 1966(Franks , 1968Schenker 1987;Pilloud 1991;Dobmeier 1996;Niklaus and Wetzel 1996;Capuzzo et al 1997), the Penninic "Zone Houillère" (Fabre et al 1987;Cortesogno et al 1993;Mercier 1993;Thélin et al 1993), and the eastern Alps (Krainer 1992(Krainer , 1993 and southern Alps (Cassinis et al 1988(Cassinis et al , 1995. Denudation had attained mid-crustal levels, where detrital fans were nourished with granitoids, migmatites and detrital white micas (Saar-Nahe basin ;Schäfer 1989;western Alps, Carme 1965a;Barféty et al 1997;Capuzzo et al 1997).…”

More than 50% of the Alps expose fragments of Palaeozoic basement which were assembled during the Alpine orogeny. Although the tectonic and metamorphic history of the basement units can be compared to that of the Variscan crust in the Alpine foreland, most of the basement pieces of the Alps do not represent the direct southern continuation of Variscan structural elements evident in the Massif Central, the Vosges-Black Forest or the Bohemian massif. The basement units of the Alps all originated at the Gondwana margin. They were derived from a Precambrian volcanic arc suture fringing the northern margin of Gondwana, from which they were rifted during the Cambrian-Ordovician and Silurian. A short-lived Ordovician orogenic event interrupted the general rifting tendency at the Gondwana active margin. After the Ordovician, the different blocks drifted from the Gondwana margin to their Pangea position, colliding either parallel to Armorica with Laurussia or with originally peri-Gondwanan blocks assembled presently in Armorica. From the Devonian onwards, many basement subunits underwent the complex evolution of apparently oblique collision and nappe stacking. Docking started in the External massifs, the Penninic and Lower and middle Austroalpine units in approximately Devonian/early Carboniferous times, followed by the Upper Austroalpine and the South Alpine domains, in the Visean and the Namurian times, respectively. Wrenching is probably the best mechanism to explain all syn and postcollisional phenomena since the Visean followed by postorogenic collapse and extension. It explains the occurrence of strike-slip faults at different crustal levels, the formation of sedimentary troughs as well as the extrusion and intrusion of crustal and mantle-derived magmas, and allows for contemporaneous rapid uplift of lower crustal levels and their erosion. From the Stephanian onwards, all regions were deeply eroded by large river systems.

“…8 & Table 5), the Permian System is widespread, and may reach more than 2000 m in thickness (Toutin-Morin & Vinchon 1989; Toutin-Morin, in Cassinis et al 1992Cassinis et al , 1995Durand 2001Durand , 2006Durand et al 2002). In the Early Permian, some general W-E grabens (Toulon-Cuers, Luc, Bas-Argens, Est6rel), which are related to extensional movements, began to open on the margin of horsts trending roughly N-S/W-E along the border of the Variscan Maures massif.…”

“…There are no formations of evaporites on the surface, nor marine sediments, although occasionally marine sediments have erroneously been described. Some radiometric dating of volcanic rocks Lago et al 2004a, b) and Autunian and Thuringian macro-and microfloral assemblages (Sopefia et al 1995;Virgili in Cassinis et al 1995) are the most valid chronostratigraphical references, but it should not be forgotten that these two terms correspond to floral groups and not to temporal units. Thuringian microflora has also been found in the Zechstein and in the Changshingian and therefore its attribution to the Upper Permian is of no doubt.…”
