Seismic stratigraphy and structural setting of the Adventure Plateau (Sicily Channel)

Evidence of positive tectonic inversion in the north-central sector of the Sicily Channel (Central Mediterranean)

“…1 and 10), along which some volcanic centers (Cello 1987;Finetti and Del Ben 2005), as well as push-up structures , were identified. Most of the deformation along this structure seems to have been produced mainly during Pliocene time (Civile et al 2014), but an earlier activity cannot be excluded, as inferred by Argnani et al (1986). Thus, the deformation could be connected with the coeval emplacement of the Gela Nappe.…”

“…Inside this belt are also located the volcanic center of Linosa Island and the Nameless, Terribile and Graham banks (Fig. 1), that, together with Pantelleria Island, characterize the Pliocene to Recent widespread alkali basalt volcanism of the Sicily Channel (Calanchi et al 1989;Civile et al 2008Civile et al , 2014Coltelli et al 2016), mainly associated with the extensional phase of the channel.…”

“…Much younger volcanic manifestations were identified, on the basis of seismic profiles and bathymetric data, just out of the westernmost portion of the study area ( Fig. 1): they are relative to the Holocene volcanism of the Graham and Terrible banks (Civile et al 2014;Coltelli et al 2016).

A submerged monolith in the Sicilian Channel (central Mediterranean Sea): Evidence for Mesolithic human activity

“…This tectonic extension was also responsible of the formation of the two volcanic islands of Pantelleria and Linosa, and other submerged volcanic edifices lying along the eastern margin of the Adventure Plateau (Calanchi et al, 1989;Rotolo et al, 2006;Lodolo et al, 2012). It occupies the north-western sector of the Sicilian Channel, where available oil exploratory wells have shown that the sedimentary sequence ranges from Triassic to Plio-Quaternary, with various hiatuses associated with long periods of aerial exposition and/or erosion (Civile et al, 2014). The Adventure Plateau is the shallowest part of the entire Sicilian Channel, and is punctuated by several isolated banks, some of them rising up to less than 10 m below sea level (Colantoni et al, 1985).…”

The Graham Volcanic Field Offshore Southwestern Sicily (Italy) Revealed by High-Resolution Seafloor Mapping and ROV Images

“…The volcanic centers of the GVF, those on the Nameless Bank and in the nearshore of Capo Granitola-Sciacca coast, together with Cimotoe volcanic seamount (Civile et al, 2015(Civile et al, , 2018Coltelli et al, 2016;Lodolo et al, 2019a), are aligned along a nearly N-S oriented belt extending southwards for almost 200 km up to Linosa Island. This belt was related to a lithospheric-scale transpressive transfer zone (the Capo Granitola-Sciacca Fault Zone, CGSFZ; see inset in Figure 1) between the western and eastern sectors of the Sicily Channel Rift Zone, characterized by different amount of rifting (Argnani, 1990;Civile et al, 2014Civile et al, , 2018. The CGSFZ is also positioned between two tectonically independent sectors of the offshore part of the Sicilian-Maghrebian Chain, characterized by different deformation ages, structural trends and tectonic evolution, playing a key role in the Neogene-Quaternary geodynamic evolution of the region (Argnani, 1990;Corti et al, 2006;Civile et al, 2008Civile et al, , 2014Civile et al, , 2018Ghisetti et al, 2009;Calò and Parisi, 2014;Cavallaro et al, 2017;Fedorik et al, 2018;Ferranti et al, 2019).…”
