Abstract: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 t… Show more
“…The cliffs are part of the Val Marecchia Nappe (called Coltre della Valmarecchia ) which is a complex stack of allochthonous and semi-allochthonous units emplaced in a foredeep basin during the Late Miocene to Early Pliocene (Fig. 3 , Cornamusini et al 2017 ). The Nappe is formed by Ligurian Units overlain by Epi-Ligurian ones.…”

Born from a desire to promote the landscape by integrating its origins and physical aesthetics with its naturalistic, cultural, and artistic heritage, we develop narratives about three locations in central Italy, telling them in the language of popular science, supported by the language of art. The different disciplines of science, poetry, and ancient music are applied to the same sites, producing emotional experiences where the encounter and interplay between different representations, and combinations of representations, become an expression of a place. The research introduces three geosites from the Marche Region, central Italy: I Sassi Simone e Simoncello, La Grotta della Beata Vergine di Frasassi, and the Infernaccio Gorge, in order to propose our multidisciplinary approach to the international public. These have been chosen for their value and charm, for their different processes of genesis and evolution, and for the cultural context and feelings they evoke. In a new approach to science communication, our study uses art in the form of music and poetry to encourage people to learn about landscapes. The paper explains the genesis and evolution of the three places, suggests trekking itineraries, includes a poem written specifically for each site, and describes a piece of ancient music and video and cultural offerings relating to each location. Our goal is to educate by fashioning a new perception of landscapes, starting with their physical beauty, and then building on scientific research in co-operation with arts, to improve what we know about their problems and weaknesses, but also about their culture and other strengths.

“…The Ligurian Units, characterized by argillitic clays, are the main responsible for the translating movement of the formations that lay above them, providing a preferential detachment zone to the migration, which occurred during the Miocene Apennine chain uplift. A complex mechanism for the emplacement of the Valmarecchia Nappe is proposed in [20], which includes a tectonic origin due to the Mt. Nero Thrust and a submarine gravitational sliding development within the foredeep basin.…”

Studying fluvial dynamics and environments, GIS-based analyses are of fundamental importance to evaluate the network geometry and possible anomalies, and can be particularly useful to estimate modifications in processes and erosion rates. The aim of this paper is to estimate short-term erosion rates attributable to fluvial processes in two sample catchment sub-basins of the Marecchia river valley, by conducting quantitative morphometric analyses in order to calculate various descriptive parameters of the hierarchisation of the river networks and the mean turbid transport of streams (Tu). Sediment yield transported by streams can in fact partially express the amount of erosional processes acting within the drainage basin. The study area includes two sub-basins of the Marecchia valley (Senatello river, 49 km2 and Mazzocco river, 47 km2), chosen because of their similar extent and of the different location in the major catchment basin. Starting from geomorphological maps of the two river basins, the Tu parameter has been calculated and converted in short-term rate (average value 0.21 mm/year). Moreover, the comparison of these short-term mean data with the uplift rates calculated on a regional scale (0.41 ± 0.26 mm/year) in the Marecchia valley confirms that the northern Apennines may represent a non-steady state system.
“…The Val Marecchia Nappe (e.g., Ruggieri 1958Ruggieri , 1970Veneri 1986;Ricci Lucchi 1987;de Feyter 1991;Conti 1994), widely exposed in the upper Tiber, Savio, Marecchia and Foglia valleys, constitutes the structurally highest nappe within the frontal parts of the Tuscan-Romagnan Apennines (Boccaletti et al 1987;Conti 1994;Cornamusini et al 2010;and references therein). This nappe overthrusts both Tuscan and Umbro-Marchean units, including the earlier formed tectonic contact between these units (Fig.…”

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.
