“…The CI eruption was followed by minor explosive episodes (Orsi et al, 1996;Cole et al, 1994). The NYT eruption, 14 C dated to about 12k yr BP (Alessio et al, 1973), and recently 39 Ar/ 40 Ar dated at 15k yr BP (Deino et al, 2004), is an important phreatomagmatic episode linked to the origin of the present Campi Flegrei caldera (Lirer et al, 1987). Post-NYT Campi Flegrei activity is represented by a good deal of minor purely magmatic and phreatomagmatic episodes with vents located inside the caldera; the last eruptive event formed the Monte Nuovo cone in AD 1538.…”

Twenty-one primary pyroclastic layers were found embedded in the lacustrine sediments of the San Gregorio Magno basin (Southern Apennines). These sand-sized layers were characterised by a noticeable juvenile fragments content and by a sharp basal contact with the underlying clay and silt sediments. The tephra layers have been correlated with terrestrial counterparts from well-known eruptive events of the Campanian volcanic area, or with reference layers from deep sea sediment cores and from the Monticchio maar sequence. The investigation of the San Gregorio Magno tephra layers made it possible to deduce that lacustrine sedimentation at San Gregorio Magno basin began before 170k yr BP and lasted at least until the emplacement of the Neapolitan Yellow Tuff, which occurred about 15k yr BP. The tephrochronology allowed determination of the varying sedimentation rate that occurred in the basin. Correlation of the lacustrine record with marine sequences has allowed development of a late Quaternary tephrostratotype for southern Italy.

“…Gray color indicates products from eruptions at Ischia (text in italics to the left of the column) and Campi Flegrei (underlined text to the left of the column) However, the CI recognition and its age with respect to that of the Breccia Museo are controversial issues (Rosi and Sbrana 1987;Lirer et al 1991;Scandone et al 1991;Deino et al 1992;Perrotta and Scarpati 1994;Melluso et al 1995;Orsi et al 1996). The first controversy derives from the large amount of 14 C data available for the paleosols underlying and overlying the Breccia Museo (Alessio et al 1971(Alessio et al , 1973(Alessio et al , 1974Lirer et al 1991), which give scattered results (CI younger than 40 ka to younger than 21.3 ka). The 14 C age determinations are in contrast with the K-Ar age of 38.5-38.2 ka and the 40 Ar/ 39 Ar age of 37 ka, both measured on sanidine from the Breccia Museo at Monte di Procida (Cassignol and Gillot 1982;Deino et al 1992), as well as with the 40 Ar/ 39 Ar average data of 39.2 ka from CI sarridines (De Vivo et al 2001).…”

Procida volcanic history: new insights into the evolution of the Phlegraean Volcanic District (Campania region, Italy)

New stratigraphic, major-and trace-element, and Sr-, Nd-and Pb-isotopic data on volcanic deposits older than 14 ka from the island of Procida, Italy, are presented and compared with published analyses from the rest of the Phlegraean Volcanic District (PVD). Procida rocks range in composition from basalt to shoshonite and trachyte and show Pb ratios varying within the ranges 0. 70523-0.70678, 0.512539-0.512630, 18.99-19.29, 15.67-15.69 and 39.10-39.39, respectively. The presence of a compositional gap in the range SiO 2 =54-59 wt % is evidence of magma bimodality, and suggests that the feeding magmatic system was formed by at least two different reservoirs located at different depths. Geochemical and isotopic variations with increasing differentiation can be explained by fractional crystallization mechanisms, that in some cases were associated with crustal contamination that occurred in both deeper and shallower reservoirs; the most evolved magmas formed in the shallower one. Mixing/mingling processes also occurred. The variation of isotopic composition through time observed both for Procida and for Campi Flegrei and Ischia rocks is evidence of strong affinity between magmas that erupted on the entire PVD until about 40 ka. This indicates that they share a common origin and a common plumbing system. Most of the PVD eruptive centers active until about 40 ka lie within a NE-SWoriented volcano-tectonic belt extending from the southeastern part of Ischia, through Procida and Torregaveta volcano to the northeastern sector of the present Campi Flegrei caldera. This not only indicates the existence of a link between regional structures and volcanism in the area, but also suggests that PVD magma genesis and evolution were strongly regulated by extensional tectonics. In the last 40 ka the mafic rocks erupted along this extensional structure -from Torregaveta and the islands of Ischia and Procida -indicate that it still represents an important crustal discontinuity that focuses mantle-derived magmas. Procida trachybasalts are enriched in large ion lithophile elements (LILE) and light and middle rare earth elements (LREE and MREE), and show slight negative anomalies in the high field strength elements (HFSE) relative to average MORB. A slight depletion in HREE is present. Trace element and isotope systematics can be referred to a lithospheric mantle source. The lithospheric mantle source carries intra-plate and slabderived components, the latter probably inherited from a previous subduction event.

ABSTRACT. The Avellino Pumices eruption was one of the most catastrophic volcanic events of Somma-Vesuvius, which hit prehistoric communities during the Early Bronze Age. In the last 30 yr, several authors reported assessments about its chronology, including radiocarbon datings, but with poor internal agreement and frequently with large experimental errors. A new and more accurate 14 C dating of this eruption (1935-1880 BC, 1 σ) was obtained at the CIRCE laboratory in Caserta (Italy) by 3 AMS measurements on a bone sample of a goat buried by the eruption, collected in an Early Bronze Age village at Croce del Papa (Nola, Naples). These results were verified by other measurements on several samples chronologically related to the eruption. Our data show that human resettlement after the eruption occurred rather quickly but lasted only for a short time in areas affected by the volcanic products, like Masseria Rossa and San Paolo Belsito (Nola, Naples), according to 14 C dating of archaeological samples collected below and above the eruption deposits. The state-of-the-art chronology of this eruption, emerging from the results obtained in this work as well as from data in the literature, is discussed.
