Palaeogeographical evolution of the Egadi Islands (western Sicily, Italy). Implications for late Pleistocene and early Holocene sea crossings by huma…

2019

Abstract The continental shelf morphology offshore of western Sicily suggests that during the Last Glacial Maximum (LGM, 20 ka cal BP), two of the Egadi Islands, Favignana and Levanzo, were connected to Sicily by a wide emerged plain, while Marettimo was only separated from the other islands by a narrow channel. We studied the relative sea-level variation from the LGM until today, focussing on two important time slices: the Mesolithic (9.5–13 ka cal BP) and the Neolithic (6.5–7.5 ka cal BP). In this research, we discuss a sea-level rise model by means of geomorphological, archaeological and geophysical observations and new radiocarbon dating of marine and terrestrial fossil fauna. The resul…

Gathering different marine geology data (seismics, acoustics, sedimentological) to investigate active fluid seepage (AFS) in the southern region of t…

2017

Active Fluid Seepage (AFS) at the seafloor is a global phenomenon associated with seafloor morphologies in different geodynamic contexts. Advances geophysical techniques have allowed geoscientists to characterise pockmarks, mounds and flares associated with AFS. We present a range of marine geological data acquired in the central Mediterranean Sea (northern Sicily continental margin, northwestern Sicily Channel and offshore the Maltese Islands), which allow us to identify AFSs. The AFSs are spatially distributed as clusters, aligned or isolated at different depths, ranging from few decametres offshore the Maltese Islands, up to 400 m offshore north Sicily and in the northwestern Sicily chan…

Toward an update of the structural model in Italian submerged areas: contributions from the EMODnet Geology Project

2016

The European Marine Observation and Data Network (EMODNet) Project aims at the collection of as many existing data as possible on European Seas to be represented on digital maps at the 1:250,000 scale, accessible via web through a dedicated portal. It is articulated into different Lots concerning Bathymetry, Geology, Biology, Chemistry, Physics, Physical Habitats, Human activities. The Geology Lot is realized by a Consortium in which the Geological Survey of Italy is partner. EMODnet Geology requires the compilation of a number of layers subdivided into Work Packages (WP), referring to seafloor sediments grainsize, sedimentation rates, Quaternary geology, pre-Quaternary geology and stratigr…
