“…On the other hand, when interpreting the Val Marecchia Nappe as a part of the Sub-Ligurian Domain some problems arise because the latter is considered to be at least partly an oceanic belt, and because of its paleogeographic location. Evidently, as already pointed out by Vai and Castellarin (1992) and Perrone et al (1998Perrone et al ( , 2008, development and age of the stratigraphic succession of the Val Marecchia Nappe are very similar to those of the Sub-Ligurian units. For example, the Groppo di Vescovo Limestone Fm., which characterizes the Sub-Ligurian Units in the Emilian Apennines and which consists of carbonate turbidites, revealed the same Oligocene age of the Monte Morello Fm.…”

“…Consequently, it is widely believed that the Val Marecchia Nappe sedimentary succession has been deposited in the easternmost zone of the External Ligurian Domain, close to the western margin of the Adria Plate; it became deformed in the Middle-Late Eocene following the Ligurian tectonic phase, after which it was overlain by the Epiligurian piggy-back basins. In contrast, Vai and Castellarin (1992) and Perrone et al (1998) questioned this interpretation and considered the Val Marecchia Nappe as originating from the Sub-Ligurian Domain (Fig. 1).…”

The succession of the Val Marecchia Nappe (Northern Apennines, Italy) in the light of new field and biostratigraphic data

This paper challenges the classical idea that the Val Marecchia Nappe, the highest of the north-eastern Apennines, is a nappe that originated from the External Ligurian Domain and consisting of Upper Cretaceous-Middle Eocene rocks, accreted to the Palaeo-Apenninic Chain in the Middle-Late Eocene due to the Ligurian tectonic phase. Its succession comprises a Middle-Late Jurassic ophiolitic substratum and its sedimentary cover of Late Jurassic to Early Miocene age. This succession is quite similar to those of the North-Calabrian and Parasicilide Units of the Southern Apennines and of many Maghrebian and Betic Flysch Domain Units, all originating from the Western Tethys and deformed since the Early Miocene. The Val Marecchia Nappe succession was likely deposited in an oceanic realm that differs from that of the Ligurian Domain and was located in a more external palaeogeographic position with respect to that of the Ligurian Domain. The oceanic realm of the Val Marecchia Nappe constituted the northwards extension of the Maghrebian Flysch Basin-Lucanian Ocean system.

The Ligurian Unit formations span in age from Early Cretaceous to Middle Eocene for the Marecchia Valley area (part of these units are ascribed to a more external domain by Perrone, De Capoa, & Cesarini, 1998and by De Capoa et al, 2015.…”

A detailed geological map at 1:50,000 scale of the Marecchia Valley and adjoining areas\ud (Northern Apennines, NA, Italy) is presented here. The Marecchia Valley represents a\ud geological ‘unicum’ for the NA and it has been the focus of scientific debate for a long time,\ud due to the occurrence in the area of the ‘Coltre della Val Marecchia (CVM)’, a complex stack\ud of allochthonous and semi-allochthonous units emplaced in a foredeep basin during the Late\ud Miocene to Early Pliocene. In order to clarify the geological evolution for this area, the\ud lithostratigraphic relationships and the tectonic framework have been studied, allowing\ud better understanding of the complex relationships between tectonics and sedimentation.\ud The main result has been a new evolutionary framework for this sector of the orogen during\ud the Late Miocene-Early Pliocene. Several new findings about the geological-structural setting\ud and stratigraphy, result from the geological map presented here. These are overall supported\ud by stratigraphic and tectonic evidence, which suggest time and modes of the CVM\ud allochthonous emplacement within the Messinian-early Pliocene foredeep successions.\ud Relationships between the allochthonous and autochthonous formations allowed recognition\ud of two different bodies in the CVM, gravitationally emplaced following different trajectories\ud and timing

“…Instead, in the CalvanaLucania Basin, deep marine successions developed above the Jurassic oceanic crust (Plesi et al 2002) up to the Early Miocene (Perrone et al 1998;de Capoa et al 2003;Di Staso et al 2009;and references therein).…”

recognizable in different tectonic units of the Apennines, Maghrebian, and Betic Chains show petrofacies and chemical-geochemical features related to a similar calc-alkaline magmatism. The characterization of this event led to the hypothesis of a co-genetic relationship between volcanic activity centres (primary volcanic systems) and depositional basins (depositional processes) in the Early Miocene palaeogeographic and palaeotectonic evolution of the central-western Mediterranean region. The results support the proposal of a geodynamic model of this area that considers previously proposed interpretations.
