“…The White Trachitic Tuff (WTT), emplaced around the volcanic edifice, is the product of the major KS eruptive phase (Giannetti and Luhr 1983;Ballini et al 1989;Giannetti 1990;Valentine and Giannetti 1995). The WTT consists of white and gray trachytic pumices (Giannetti and Luhr 1983) with few lythic accumulation zones (Giannetti and De Casa 2000). The termination of KS period is marked by the emplacement of two effusive, strombolian, latitic domes: the Lattani and the S. Croce domes (Rouchon et al 2008).…”

This is the first hydro-geochemical investigation carried out on the Roccamonfina Volcanic Complex groundwaters. The chemistry of Roccamonfina waters is defined by water-rock and water-rock-gas interactions. In fact, interactions between rocks of the first eruptive high-K formations and circulating groundwaters are recognized by high K concentrations. On the other hand, inverse concentration of calcium versus alkali metals is related to two different rock interactions occurring in different areas of the volcano: (a) within the caldera where groundwaters flow within latite and pyroclastic formations releasing calcium, and (b) similarly at the base of the volcano where groundwaters flowing from surrounding carbonates got strongly enriched in Ca. These geochemical processes are also associated with K (SE of caldera) and Mg/Ca (in sites located at the NE base of the volcano) decrease. Completely different dynamics occurs at Riardo groundwaters (SE). Here waters are the result of a mix between the Roccamonfina deep aquifer and the carbonate aquifer of the Riardo plain. Rich-CO 2 emissions make these waters strongly mineralized. Minor elements show a similar geochemical behavior of major ions and are crucial defining interactions processes. The evolution of Roccamonfina groundwaters is also evident along the simultaneous enrichment of Ba, Sr, and Ca. Ba increase is the result of deep local carbonate alteration enhanced by CO 2 emissions and, the lower Sr/Ca ratio, from 10 to 2 (ppb/ppm), is also due to the same process. In the light of our results the Roccamonfina aquifer can be schematically divided into two main reservoirs: (a) a superficial aquifer which basically follows the volcanic structure morphology and tectonics and (b) a deeper reservoir, originating within the oldest Roccamonfina volcano ultra potassic lavas and then flowing into the carbonate aquifers of the neighboring plain. Eventually, the chemistry of the Roccamonfina aquifer does not show any specific and visible pollution, contrary to what happens in the volcano surrounding plains. In fact, only 14% of the samples we collected (206) show a NO 3 content[30 mg/l. These sites are all located at the base of the volcano, near the plain.

“…The formation of the summit caldera sector collapse around 400 ka marked the passage to the second period of activity characterized by plinian paroxistic volcanic activity with the eruption of five main, caldera forming pyroclastic flow units that are the Brown Leucitic Tuff and the succession of the White Trachytic Tuffs (e.g. De Rita and Giordano 1996; Giannetti and De Casa 2000;Giannetti 2001). Leucite-free lava flows characterized the third and last period of activity in the form of intra-and peri-caldera trachytic domes (Cole et al 1992).…”

Shear wave velocities of the crust and upper mantle are defined beneath the Roccamonfina volcano and surrounding Apennines (southern Italy) from the simultaneous nonlinear inversion of the local group velocity dispersion data, obtained from seismic events recorded in 1988-2004 at Roccamonfina station of the INGV-RSNC network, and regional dispersion data obtained in previous studies. The main features of the representative V S models are a carbonatic basement and a low velocity zone at 6-10 km of depth. The sedimentary succession is *5 km thick below the Roccamonfina volcano and lays above a high V S (3.8 km/s) ascribable to solidified magma body, while it is *10 km thick below the surrounding Apennines. A low velocity layer with an average thickness of 10 km is detected below the Roccamonfina volcano which can be associated with the presence of partial melting and interpreted as magmatic reservoir. Such low velocity layer, also found below the surrounding Apennines but with a reduced thickness of 2-3 km, extends to the Campanian Plain and to the Neapolitan volcanic area, from Campi Flegrei to Somma-Vesuvius.
