Basement and early (pre-Alpine) history

U and Th content in the Central Apennines continental crust: A contribution to the determination of the geo-neutrinos flux at LNGS

“…(Bernoulli, 2001;Vai, 2001) mainly composed by conglomerate and sandstones (Reservoir b3). In some area a Permian shallow-marine carbonate succession also occurs (see Gargano 1 and Puglia 1 wells in Apulia).…”

“…(Crescenti et al, 1969;Bernoulli, 1972Bernoulli, , 2001Parotto and Praturlon, 1975;Coltorti and Bosellini, 1980;Vai, 2001;Finetti et al, 2005a among others). Telford et al (1990) and are in agreement with the densities assumed by Laske et al (2001) for the rest of the world.…”

Carboniferous continental margin deposits in southern Tuscany, Italy: results from geological mapping of the geotopes Farma Valley and San Antonio Mine Area

“…139-150), the Tuscan geological basement is part of the Hercynian nappe-and outer zones (palaeoadriatic wedge), established between the axial zone (Corsica and NE-Sardinia) to the northwest and the panafrican consolidated Hercynian foreland (Adria) to the southeast (Figure 4). Proved constituents of the Tuscan geological basement are Ordovician to early Devonian pelagites (graptolite shales, palaeontologically dated Orthoceras limestones, nodular red limestones) and volcanics (porphyroids, basites and basalts) (Vai 2001a). Gneisses, amphibolites, micaschists and other metasediments are expected constituents of this lowermost tectonic unit Garfagnoli et al 2005).…”

“…It will be important to ascertain, if these phases of organic carbon are related to the global climatic and oceanographic changes, which caused the oceanic anoxic events known for the late Frasnian to late Mississippian age (Kaiser 2005;Negri et al 2006). According to Vai and Cocozza (1986), Gattiglio et al (1989) and (Vai 2001a), similar chert lithofacies of the Central-West Mediterranean Palaeozoic are present in Ordovician-early Carboniferous foreland-and basin-deposits of South and Central Sardinia, in the Longobucco-and Stilo-Units of Calabria, in Eastern Elba as well as in the Apuan and Carnic Alps.…”

Transtensional Tectonics Played a Key Role During the Variscan Cycle in the Sardinia-Corsica Massif

“…The emergence is pre-dated by the Arenig deposits at the top of the Cabitza Fm and post-dated by the Caradocian deposits of the Tuviois Fm (Vai & Cocozza, 1986) This last consists in fluviolacustrine-shallow marine sequences, formed after short-lived emergence. The Silurian-Devonian succession is usually considered the result of a worldwide climatic transgression (Vai, 2001). …”
