Abstract:The Plio-Quaternary magmatism in the Tyrrhenian Sea area exhibits wide compositional variations, which cover almost entirely those observed for volcanic rocks worldwide. Some volcanoes (Etna, Iblei, Sardinia, etc.) range from tholeiitic to Na-alkaline, and display elemental and isotope signatures typical of FOZO and EM-1 ocean-island basalts (OIB). Other volcanoes (Aeolian Arc, Italian peninsula) range from calc-alkaline-shoshonitic to K-alkaline, exhibit typical 'subduction-related' trace element signatures (low Ta-Nb, high Rb-Cs-LREE), and show a large range of radiogenic isotope ratios, from mantle-like in the Aeolian Arc to crustal-like in central Italy. Geochemical data suggest that OIB-type magmatism originated in lithosphere-asthenosphere sources that were unaffected by recent subduction. In contrast, subduction-related magmas come from mantle sources that underwent Eocene to present mixing with various amounts and types of subducted crustal components. Fluxing of the mantle wedge by water-rich fluids from a mid-ocean ridge basalt-type slab occurred in the southern Tyrrhenian Sea, whereas interaction between peridotite and various types of sediments occurred in central Italy. These contrasting styles of mantle contaminations relate to the nature (oceanic or continental) of the foreland, slab geometry and pre-metasomatic mantle compositions, which vary greatly along the Apennine arc and are the reason for the formation of the wide variety of orogenic magmas in Italy.

“…In this framework, the Alps-Apennines orogenic system originated, involving continental and oceanic crustal units that were affected, at a very different extent, by metamorphic and tectonic reworkings (see Dal Piaz, 2010 for a review). In the early Oligocene, magmatic complexes intruded the orogenic belt as a consequence of the crust subduction (see Alagna, Peccerillo, Martin, & Donati, 2010, for a review). Contemporaneously, since the middle Eocene, synorogenic sedimentary basins developed: the middle Eocene-early Oligocene Alpine foreland basin in the outer part of the Alpine chain, the Eocene-Messinian Tertiary Piemonte Basin (BTP) and the Pliocene-Quaternary basins in the inner part.…”

The geological map of Piemonte Region (Italy) is a graphic representation of the geology of the region, grounded on a large geodatabase, that can be also browsed as an interactive scalable map (GeoPiemonte Map) using a WebGIS application. The Map, produced at 1:250,000 scale, is the first original release of the 'GeoPiemonte Map' project. The geological data represented on the map derive from a thorough revision of available geological maps and literature, integrated with unpublished original data. The revision and harmonisation of existing and new data have been based on explicit criteria used for the classification of geologic units and their representation on the Map. These criteria firstly aimed at providing a lithostratigraphic, hierarchic subdivision of Piemonte geologic units and describing them using shared concepts and vocabularies, consistent with IUGS Descriptive Standards for the Geosciences. ARTICLE HISTORY

show abstract

“…The present-day geological and physiographic framework of the central Mediterranean was determined by a complex series of events related to the convergence of the African and Eurasian tectonic plates (Conticelli et al 2007;Alagna et al 2010;Conticelli et al 2010b). The Ionian-Adriatic lithosphere was subducted westwards and north-westwards beneath the Eurasian plate, resulting in the progressive closure of the intervening Tethyan ocean basins.…”

“…In the Eocene, convergence began in the Apennine orogen as a result of westward subduction of the Adriatic lithosphere beneath the southern European margin (Alagna et al 2010;Conticelli et al 2010b). The progress of these movements was expressed in a complex series of events involving sedimentary basin formation, deformation, and rifting resulting in north-south and north-west-south-east trending extensional basins and varied but widespread subduction-related magmatism.…”

Geochemical Methods for Sourcing Lava Paving Stones from the Roman Roads of Central Italy

This paper documents the results of in situ analysis of 306 lava paving stones and 74 possible source rocks using pXRF. Data were collected from sites both in the city of Rome—on major roads beyond the city (including the Viae Flaminia, Cassia, Clodia, Praenestina and Appia)—and in the city of Ostia. Comparison of the pXRF data with lava compositional data from the geological literature allows broad identification of possible sources. The results point to quite distinctive patterns of exploitation for the city of Rome and Ostia, utilizing the Alban Hills lava flows, and the roads of the middle Tiber Valley, drawing on lava flows associated with the Vico and Sabatini volcanoes. The results show the potential of pXRF to produce data to elucidate the exploitation of lava flows for paving the Roman roads.
