“…Homologous successions can be found eastward over long distances similar to those in the Lesser Kabylia (northern Algeria) where the Achaiches series also contain radiolarites with limestone microbreccias (Bouillin 1979, Durand-Delga 1979. In the Sicily-Calabrian Arc, Tithonian radiolarites of the Contarada Lanzeri Fm (Bouillin et al 1995) and the Caloveto-type series (Santantonio & Teale 1987) are considered to be lateral equivalents of the flysch substratum remnants.…”

International audienceSince the 1970s, radiolarians have been used extensively to study and characterize basin successions from the peri-Mediterranean regions. However, no data was ever produced in Tunisia in spite of the occurrence of Jurassic siliceous series previously described by many authors. Our study presents the biostratigraphical results obtained on sections from the Jédidi Formation, which characterizes the basinal series of the Tunisian Trough. We provide new direct age determinations from the base, the middle part and the top of the formation, which ranges from the latest Bajocian–middle Bathonian to the Oxfordian (Tethyan biozones UAZ 5-6 to 8-9). The onset of these radiolarianbearing series of the Tunisian Trough, adjacent to partly coeval Ammonitico Rosso successions, is interpreted as resulting from regional palaeotopographical gradient and palaeoceanographical conditions. Inaccurately interpreted as “true” radiolarites, theses series are different from coeval radiolarites of the Maghrebian “Dorsale calcaire” and from more recent homologous deposits of the Flysch domain. They are instead correlative with series exposed in the Babors and the west-Numidian ranges of northern Algeria that belonged to the same Jurassic North African margin of western Tethys. During Alpine convergence s.l., this external domain was overthrust by nappe complexes of the Maghrebide inner zones and the Flysch domain units

“…In northern Calabria, sedimentation started in the early on October 3, 2012 gsabulletin.gsapubs.org Downloaded from Hettangian with fl uvial red beds (Baudelot et al, 1988) resting on the Paleozoic basement, and the Triassic is entirely missing (Young et al, 1986;Mariotti et al, 2007). Much of Sardinia and Calabria (Calabride units;Amodio Morelli et al, 1976;Santantonio and Teale, 1987;Mariotti et al, 2007) therefore stood emergent (central and eastern Sardinia; Carmignani et al, 2001), and/or were uplifting (Calabria; Festa et al, 2003), or were covered by very shallow waters in conditions of tectonic stability ("epicontinental sea") and extremely slow subsidence (western Sardinia) through most of the Early Jurassic.…”

“…Petrologic characteristics of the sandstone and conglomerate suggest that the sedimentary strata of the two main late Miocene wedge-top depozones of the southern Italy foreland-basin system were derived mainly from the nearby crystalline (plutonic and metasedimentary rocks) and associated Mesozoic to early Miocene sedimentary source areas. The key candidate for the main source areas is the Sila Mountain allochthon, where Paleozoic low-grade to high-grade metamorphic rocks and plutonic rocks are widely present (the Sila unit) and are overlain by Mesozoic rifted-continental-margin sequences (Longobucco Group; e.g., Zuffa et al 1980;Santantonio and Teale 1987) or early Miocene (Aquitanian) clastics (Paludi unit; e.g., Bonardi et al 2005). In spite of the rather homogeneous detrital modes of the entire basin fill, some significant petrologic differences allow differentiation of diverse sandstone petrofacies corresponding to the key tectonic and climatic signals within the inner portions of the southern Italy foreland-basin system.…”

The composition and stratigraphic relations of sandstones and associated conglomerates derived from erosion of the northern Calabrian terranes provide important constraints for paleotectonic and paleogeographic models of the Neogene wedge-top depozone evolution of the southern Italy foreland basin system.After onset of continental collision in the southern Italy orogenic belt during late Oligocene to early Miocene, the Calabrian Arc drifted northeastward, accreting over the Adria lithosphere during mid to late Miocene time. Since the Tortonian, the northern Calabrian terranes represented an uplifted thrust belt in which along its leading edge tectonic subsidence was responsible for accumulation of a thick Tortonian to Quaternary succession, dominantly siliciclastic (up to 3300 meters thick), deposited in the wedge-top depozones (Rossano and Crotone basins).Sandstone assemblages have a homogeneous quartzofeldspathic composition in the Rossano and Crotone basins, characterized by a compositional trend, through time in response to regional tectonics. Evolution of the basins fill occurred during (1) Serravallian?-Tortonian, (2) late Tortonian to early Messinian, and (3) late Messinian. Detritus shed into those basins was derived mainly from terranes within the strongly deformed Sila Mountains allochthon, which was one of the principal structural elements of the nearby northern Calabrian terranes, consisting of Hercynian plutons intruding Paleozoic (Cambrian to Carboniferous) metasedimentary host rocks, and locally having a sedimentary cover of Mesozoic (Longobucco Group) or early Miocene (Paludi unit) clastics. Low-to medium-grade metamorphic and minor plutonic grain types (metamorphiclastic petrofacies) represent the main detritus in the earliest (Serravallian?-Tortonian) sedimentation that accompanied progressive flexural bending of the western margin of the foreland-basin system. Tortonian to early Messinian time was characterized by isolation of the Mediterranean region from the global marine realm, leading to evaporite sedimentation in the foreland in addition to intense regional and local tectonics. Compositional response to those events was a marked increase in sedimentary detritus (sedimenticlastic petrofacies) related to cannibalization of early Messinian evaporite successions; after the evaporitic events within the basins and the gradual re-establishment to the normal marine conditions, sandstone detrital modes are characterized mainly by a return of the Serravallian?-Tortonian compositional modes (i.e., metamorphic-plutoniclastic petrofacies). The post-evaporitic sedimentation corresponds to a major tectonic rearrangement on both Rossano and Crotone basins related to extrusion and inversion of the basal portion of the Serravallian?-Tortonian sequences in the intermediate zone to form an intervening ''Cirò structural high.'' In the Crotone Basin during late Messinian, deposition of the Carvane Conglomerate records an abrupt sudden arrival of distinctive sedimentary containing clasts of detritus of reddish l...
