“…In Molise, partially to fully reset ages as young as ≥1 Ma are from lower Messinian sediments that were over-thrust by the far-traveled Sicilide units, which represent upper Messinian-lower Pliocene wedge-top basins (Cosentino et al, 2018). In this region, intermontane basin are not present and cooling might have started during the Pleistocene, as indicated by the thermal modeling of one of the partially reset samples.…”

Transition from slab roll-back to slab break-off in the central Apennines, Italy: Constraints from the stratigraphic and thermochronologic record

et al. 2021

Stratigraphic and thermochronologic data are used to study the processes that shaped the topography of the central Apennines of Italy. These are part of a major, active mountain belt in the center of the Mediterranean area, where several subduction zones control a complex topography. The Apennines were shaped by contraction at the front of the accretionary wedge overlying the subducting Adria microplate followed by extension at the wedge rear in response to eastward slab roll-back. In the central Apennines, intermontane extensional basins on the western flank rise eastward toward the summit. We contribute with new data consisting of 28 (U-Th-Sm)/He and 10 fission track ages on apatites to resolve a complex pattern of thermal histories in time and space, which we interpret as reflecting the transitional state of the orogen, undergoing a two-phase evolution related to initial slab retreat, followed by slab detachment. Along the Tyrrhenian coast, we document cooling from depths ≥3−4 km occurring between 8 and 5 Ma and related to the opening of marine extensional basins. Post−5 Ma, a broader region of the central Apennines exhibits cooling from variable depths, between <2 km in most areas and ≥3−4 km in the northeast, and with different onset times: at ca. 4 Ma in the west, at ca. 2.5 Ma in the center and northeast, and at ca. 1 Ma in the southeast. Between 5 and 2.5 Ma, exhumation is associated with modest topographic growth during the late stages of thrusting. Since 2.5 Ma, exhumation has concurred with the opening of intermontane basins in the west and in the east, with regional topographic growth and erosion, that we interpret to be associated with the locally detaching slab.

“…The late Tortonian and Messinian migration phases were responsible for the construction of almost 90% of the chain (Cipollari & Cosentino, 1995a; Cosentino et al, 2010; Vitale & Ciarcia, 2013). The late Tortonian and Messinian compressional tectonics were also important for the orogenesis of the southern Apennine chain (Cosentino et al, 2018; Vitale & Ciarcia, 2013, 2018) and the Sicilian Maghrebides (Gugliotta, 2012; Gugliotta & Gasparo Morticelli, 2012). Late Tortonian and Messinian foredeep and wedge‐top basins also developed in response to the deformation of the Betic Cordillera (e.g., Crespo‐Blanc, 2007; Crespo‐Blanc et al, 2016; Jiménez‐Bonilla, Expósito, Balanyá, Barcos, et al, 2015; Jiménez‐Bonilla, Expósito, Balanyá, Díaz‐Azpiroz, et al, 2015; Mattei et al, 2006; Ruiz‐Constán et al, 2009; Viseras et al, 2005; Weijermars, 1985) and the Rif Chain (Bernini et al, 1999; Chalouan et al, 2008; Di Staso et al, 2010; Roldán et al, 2014; Sani et al, 2000, 2007; Zizi, 1996).…”

During the Neogene, the Western Mediterranean subduction-related orogen developed under differing modes and senses of subduction, resulting in the formation of the Apennines, Maghrebides, Rif, and Betics. In this work, we present the Neogene kinematic evolution of the Rif, based on literature data and new results from structural-stratigraphic analyses and biostratigraphic investigations carried out in the External Zone of the Rif. We analyzed three stratigraphic sections: Dar Zhirou, Saf Lahmame, and Seguedla. The results of these analyses allow us to reconstruct a wide Tortonian-Messinian wedge-top basin in the Tanger-Al Manzla area, when the leading edge of the Rif was at the frontal thrust of the Prerif. The presence of this wedge-top basin points to a Tortonian-Messinian compressional deformation that affected a wide area of the Rif, including the Prerif, Mesorif, and Intrarif. The late Miocene compressional deformation that affected the Mesorif and Intrarif occurred as out-of-sequence thrusting, due to renewed compressional tectonics in the internal zone of the chain triggered by the collision of the Rif accretionary wedge with the North African Margin. In the Neogene evolution of the Western Mediterranean subduction-related orogen, the late Miocene was a major pulse in the interplay between African and European plates, as evidenced by the increase in migration rates of some segments of the circum-Mediterranean fold-and-thrust belt, the out-of-sequence thrusting in the Rif, as well as the occurrence of late Miocene imbricate thrust structures in oceanic fracture zones of the African Plate (Central Atlantic Ocean).

“…In the Marecchia river valley (Gennari et al, 2013) and in Irpinia (Matano et al, 2005) the PLG unit rests conformably above a pre-MSC shelfal shale succession. Conversely in the Molise area Cosentino et al (2018), having observed that the PLG unit rests indistinctly above the Varicolored Clays (Cretaceous-Paleogene) or the Faeto flysch (Aquitanian-lower Messinian) deposits, suggested the presence of an unconformity at its base. In the area south-west of Termoli, between the Saccione and the Trigno rivers, 13 boreholes crossed an evaporite unit that can be assigned to PLG on the basis of the analogies in term of thickness and trend of the geophysical logs with that drilled a few km to the north resting above the Autochthonous Domain.…”

“…Conversely, its top is unconformable and overlain by terrigenous deposits containing scarce hypohaline ostracods and mollusks that can be assigned to the stage 3. A reduced succession is found in the outer portion of the Molise allochthonous both in outcrop and subsurface, including blocks of PLG unconformably capped by the Lago-Mare deposits (Cosentino et al, 2018).…”
