Mesozoic tectonics and volcanism from Tethyan rifted continental margins in western Sicily

2009

Tectonic and volcanic features from the Jurassic-Cretaceous carbonate successions of Rocca Busambra, Balatelle Mount and Vicari-Roccapalumba (central-western Sicily), are here described. These areas represent the easternmost outcrops of the Trapanese domain in Sicily. The Trapanese succession consists of shallow to deep-water Meso-Cenozoic deposits formed in a carbonate platform to pelagic plateau depositional setting. Detailed field work and structural analysis detected indicate the occurrence of paleofaults with different orientation, unconformity surfaces, lateral facies changes, resedimented materials and volcanic products (pillow lavas and tuffitic deposits). These data combined with f…

Sismotettonica del Margine Continentale della Sicilia nord-occidentale: implicazioni per la valutazione del geohazard

2017

I processi tettonici attivi nel margine continentale della Sicilia settentrionale (MCSS) sono stati analizzati per la realizzazione della carta sismotettonica, al fine di ottenere uno strumento utile per la valutazione della pericolosità sismica della regione. La carta sismotettonica è realizzata attraverso la sovrapposizione di layer che rappresentano la distribuzione di tematismi, quali litostratigrafia, tettonica, sismicità, flussi di calore, gravimetria, magnetometria, profondità della Moho, movimenti orizzontali e verticali, frane, fuoriuscite di fluidi, evidenziando la relazione tra questi e le strutture attive. Il MCSS si trova in una zona di transizione tra la catena siciliano-maghr…

Crustal architecture and Miocene to Recent evolution of the W Calabria continental margin (Southern Tyrrhenian Sea)

Miocene to Present evolution of the Calabria Tyrrhenian continental margin (Southern Tyrrhenian Sea)

2009

The Miocene to Present evolution of the Calabria Tyrrhenian Continental Margin (CTCM, Southern Tyrrhenian Sea) are reconstructed using two ENE-WSW oriented, near-vertical seismic profiles (CROP-M27 and SISTER 11 lines). The interpreted profiles were time-to-depth converted, merged and translated in a geological section, which was also extended to the Tyrrhenian bathial plain and the Calabrian arc using wide-angle seismic data [Scarascia et al., 1994], and tested with gravity modelling. Across the CTCM, top of KCU is laterally variable in depth forming basins filled by Oligo-Miocene clastic to terrigenous deposits up to 1500m thick. Basins are separated by major structures with contractional…

The transition between the Marsili oceanic crust and the W Calabria rifted margin: rifting and drifting in the upper plate of the Ionian subduction z…

2012

The western Calabria continental margin forms the transition between the Late Pliocene to Recent Marsili spreading center and continental Calabria. Integrating highpenetration and -resolution upper crustal seismic images with seafloor morphology, ODP well data and geological/geophysical constraints we provide a detailed reconstruction of the architecture of the distal portion of the W Calabria rifted margin and of the adjacent Marsili “oceanic” domain (Fig. 1) and develop a scheme for the Pliocene to present rifting and drifting of the upper plate of the Ionian subduction zone. Our seismic data document the presence of stretched and thinned continental crust, less than 10 Km thick into the …

VARIABILITY OF DEPOSITIONAL SETTING ALONG THE NORTH-WESTERN SICILY CONTINENTAL SHELF (ITALY) DURING LATE QUATERNARY: EFFECTS OF SEA LEVEL CHANGES AND…

2012

The geological, geomorphological and sedimentological features of the north-western Sicily continental shelf are here illustrated with the aim to propose a geological model able to explain the Neogene-Quaternary evolution of the Sicilian continental margin in the context of the central Mediterranean region. Above the continental shelf and upper slope the sedimentary succession, showing along the different sectors of the margin considerably variable internal geometry and stratigraphic relationships with the underlying units, is interpreted as a IV order depositional sequence (Late Quaternary Depositional Sequence, LQDS) deposited during the last eustatic change (last 125 ky). The lower bound…

A simulation study for assessing the impact of energy storage systems for Fast Reserve with additional synthetic inertia control on the Continental E…

2022

This article shows the results of a simulation study on the application of battery storage systems for providing fast frequency regulation (the so-named Fast Reserve) with additional synthetic inertia control. The aim of the study is to assess the impact of the extension of the regulation provided by the FRUs to all the Continental Europe synchronous grid, with the same power proportions of the first Italian FRU auction. The simulations are conducted in two different scenarios: a base one related to 2020 and a future one related to 2040 and based on ENTSO-E projections for load and generation. The results show that, for the reference incident of 3000 MW, the frequency quality parameters in …

Active tectonics, sedimentation history and geomorphological features in the northern Sicily continental margin: implications for the marine geohazar…

2020

Starting from the assumption that seismic events in the active margins are accompanied by evidence of a depositional, geomorphologic and structural type, which constitutes the geological record of their activity, we analysed different features of the Northern Sicily continental margin (NSCM) to reconstruct the deformational field and related stress field in the Southern Tyrrhenian sea. As an outcome of this project we were going to obtain seismotectonic setting and mapping to provide a powerful tool in managing and assessing the marine geological hazards. The study area extends from the San Vito Peninsula to the Termini Gulf along the NSCM, including the Ustica island, and is located in a t…
