Multidisciplinary approach for outcropping and subsurface Permian-Cenozoic deepwater carbonates (Central Sicily): outcome for paleogeography of the S…

2016

An integrated stratigraphic study of the outcropping and buried Permian-Cenozoic deep-water carbonate successions have been performed. These successions form some of the tectonic units, mostly buried beneath the Late Neogene sedimentary cover, in the fold and thrust belt of Central Sicily. Three main successions, pertaining to the well known Lercara, Imerese and Sicanian domains, have been reconstructed on the basis of a detailed facies analysis, seismostratigraphic interpretation, biostratigraphy (mostly based on palynological data) and comparison between outcropping and subsurface deep-water sediments. The main results reveal a continuous sedimentation of the deep-water Southern Tethyan S…

Syn-sedimentary tectonics during early Pliocene time in the northern Madonie Mountains (Sicily

2008

Tettonica sinsedimentaria del Pliocene inferiore nei Monti delle Madonie settentrionali (Sicilia). L'analisi stratigrafico-strutturale condotta in un piccolo bacino infra-pliocenico nelle Madonie settentrionali (Lascari-Capo Plaja) permette di descrivere un evento tettonico sin-sedimentario. La sinclinale EW in cui si sviluppa il bacino sintettonico appartiene ad un sistema di pieghe nord vergenti che deformano un piano di sovrascorrimento più antico (Langhiano-Serravalliano). La geometria di crescita che caratterizza il pattern stratale dei depositi pliocenici e la discordanza angolare alla base suggeriscono che la nucleazione di queste strutture compressionali si possa essere realizzata a…

The submerged structure and stratal architecture of the Neapolitan Yellow Tuff (NYT) caldera, offshore the Campi Flegrei, (Eastern Tyrrhenian Margin)…

2012

The Campi Flegrei is an active volcanic area defined by a quasi-circular depression that covers some 200 km2 of the coastal zone of SW Italy, a large part of which develops off the Naples (Pozzuoli) Bay (Fig. 1). The area has been active at least since 60 ka BP ( Pappalardo et al., 1999), and is structurally dominated by a caldera, 6 km in diameter, associated with the eruption of the Neapolitan Yellow Tuff (NYT), a 40 km3 Dense Rock Equivalent (DRE) ignimbrite (Scarpati et al., 1993) dated at ca 15 ka BP (Deino et al., 2004), that covered the district now occupied by the city of Naples, the Campi Flegrei and a large area of the continental shelf off the Pozzuoli Bay. The volcanological evo…

Paleoecological constraints on reef-coral morphologies in the Tortonian-early Messinian of the Lorca Basin, SE Spain.

2004

Coral reefs represent one of the main carbonate factories that contributed to the control of the stratigraphic architecture of carbonate platforms, which had a widespread development during the late Miocene in the paleo-Mediterranean area. The late Miocene reef complexes of the Lorca Basin in southeastern Spain are composed of five mixed siliciclastic/carbonate units, middle Tortonian to early Messinian in age. The development of coral reefs probably ceased when the first evaporitic event occurred in the basin centre in the early Messinian. This study mainly focuses on the response of reef communities and the modifications of reef organisation to global and regional parameters. At the platf…

Carta Geologica d'Italia alla scala 1:50.000. 608, Caccamo.

2010

Il Foglio 608 "Caccamo" della Carta Geologica d'Italia in scala 1:50.000 è stato realizzato nell'ambito dl Progetto Carg con i fondi della Legge 67/88 tramite convenzione tra Servizio Geologico Nazionale (ora Ispra) e Regione Siciliana. L'area del Foglio ricade nella Provincia di Palermo e ricopre una parte della dorsale settentrionale siciliana. La carta geologica è il risultato della esecuzione di rilievi originali che hanno interessato più di due terzi dell'area e della revisione di alcuni rilievi condotti tra gli anni '80 e '90 da studiosi dell'Università di Palermo. I rilevamenti originali e le revisioni sono stati raccolti e rappresentati su sezioni topografiche alla scala 1:10.000 de…

Tectonics, climate and deposition/erosion cycles during the Quaternary in Western Sicily

2011

Continental to marine Quaternary deposits outcrop in thin and patchily exposed successions in Western Sicily, overlying a previously deformed substrate, known as the Neogene-Early Quaternary chain. These deposits are grouped in sedimentary units bounded by unconformity surfaces. The detected unconformities, often of regional extent, allows us to define seven main synthems: a) Marsala synthem is a Lower Pleistocene 2-80 m-thick body of marine/coastal calcarenites; b) Piana di Partinico synthem is made up of 1-5 m thick marine/continental clastics located on several marine terraces related to sea level highstand phases of Middle Pleistocene (Oxygen Isotope Stages – OISs - 17-7); c) Polisano s…
