The geology of Sicily has a long and complicated history that originates during the Mesozoic. The features that make up the current Mediterranean are the result of two main processes: the subduction of the African plate under the Eurasian plate and the closure of the Mediterranean Sea. Deposits of carbonate sediments and marine organisms deposited from the Tethys Sea (Upper Triassic to Lower Cretaceous), constitute the oldest rocks exposed in western Sicily. During this period, the structural setting of the area was largely dominated by transtensional plate movements resulting in fault block morphologies with alternating horst and graben structures and east-west trending normal fault systems (Hsu and Bernoulli, 1978; Nigro and Renda, 2002). The structural setting has had a strong impact on depositional environments, including: elongate shallow-water platforms, seamounts, and deep-water basins. Depositional environments at the time were largely influenced by the tectonic setting that changed several times during the Late Jurassic to Late Cretaceous. Between the Upper Jurassic and the Lower Cretaceous the tectonic structure of the region changed from a transtensional system to a strike-slip system. This period is characterized by deep calcareous deposits, shallow to intertidal seamounts, and shelf calcarenites (Catalano et al., 1998; Cirilli et al., 1999; Bellanca et al., 2002). In the Upper Cretaceous, a transition from the strike-slip phase to an extensional phase occurs, together with the reactivation of the normal faults of the African paleomargin, probably due to the change in movement between the African and European plates (Tortorici et al., 2001). Basin sedimentation continued into the Late Cretaceous following normal fa...... middle of paper ......fi streams and drainage basins were found using the Calculate Geometry tool in ArcMap. This information gave us the minimum, maximum, average and total length of the stream, along with the area of ​​the watersheds. Once this information was obtained it was used to calculate the morphometric relationships (Table 1). The sinuosity of the BRV was determined through a custom tool in ArcMap that took the length of the stream across the entire valley. After calculating the morphometric parameters, a multi-ring buffer was performed around the Strait. You essentially created rings of a specific distance (500 m in this case) around a point of interest (the Strait). The purpose here was to better understand the actual distance from the Straits to the BRV to see how feasible it would be to travel on foot to the BRV for resources.
