The study of explosive volcanism is generally focused in near-vent deposits, which provide several information for evaluating depositional processes, eruptive dynamics and evolution of the volcanic edifice. However, due to the nature of the deposits and the dynamics of volcanic explosive activity, these proximal archives may result "lacunose" and incomplete, since only the deposits of the most recent and/or volumetrically significant eruptions are recorded (Giaccio et al., 2014). In this framework, distal archives represent a powerful tool, that allows a more rigorous and complete reconstruction of the explosive history of a volcano. An increasing number of recent publications (e.g Giaccio et al., 2012, 2013a, 2013b, 2014, 2017; Lowe et al., 2011; Petrosino et al., 2014; Smith et al., 2011; Tamburrino et al., 2012) have shown the wide avaiability and utility of distal archives for volcanological purposes. As a metter of fact, the applicability of the tephrostratigraphic method requires (i) long and continuous sedimentary successions, that can preserve tephra, located in a good range of distance from (ii) sources of intense and recurrent explosive activity. These conditions are both satisfied in central-southern Apennine, where, during the Quaternary, large lake systems hosted in intermountain basins (e.g. Fucino and Sulmona), recorded tephra deposition from the pery-Tyrrhenian and insular volcanic districts. These include the Vulsini, Vico, Sabatini, Colli Albani, Roccamonfina, Somma-Vesuvius, Phlegrean Fields, Aeolian Islands and Etna volcanoes (Pecerillo 2017), which have been characterized by an intense and recurrent explosive activity during the Middle Pleistocene-Holocene. These basins have been almost continuously documenting the sedimentary history since the Late Pliocene-Early Pleistocene (Giaccio et al., 2013b, 2015b) and are in a favorable position with respect to the prevailing eastward direction of the stratospheric winds at these latitudes. Among the Apennine intermountain basins, the Fucino and Sulmona ones were found to host rich tephrostratigraphic sequences (Giaccio et al,, 2012, 2013b, 2017) documenting the explosive history of the peri-Tyrrhenian volcanoes through the Pleistocene-Holocene. However, the two lacustrine succession have been only partially studied and further stratigraphic, geochemical and geochronological analyses are required. The main goal of this PhD project is to improve the general knowledge of tempo, dynamics and evolution of the peri-Tyrrhenian Quaternary explosive volcanism by combining field investigations and laboratory analyses of tephra layers both hosted in the mentioned intermountain basins (distal deposits) and found in near-vent (proximal) deposits. Major, minor, trace element and isotopes analyses will be carried out using several analytical techniques (i.e EPMA, LA-ICP-MS, TIMS) at both national and foreign institutes. Furthermore, 40Ar/39Ar dating will be performed on pristine sanidine or leucite crystals (grain size > 250 um) from selected tephra layers suitable for this kind of analyses (i.e. tephra with abundant and relatively coarse K-rich crystals). Bayesian statistic age modeling will be instead applied for dating tephra layers interbedded within other radio-isotopically dated tephra. These analyses will provide a series of micro-textural, geochemical and geochronological data that will concur in "fingerprinting" the tephra, thus allowing the identification of their volcanic sources, and possibly of the individual equivalent eruptive unit and/or distal tephra layers (some tephra markers are in fact known only in distal settings). Finally, eruption parameters modeling will be performed at the INGV, Sezione di Bologna, under the supervision of Dr. A. Costa, using an appropriate bi- (HAZMAP) and/or three-dimensional (FALL3D) ash-disperal Eulerian software for transport and deposition of volcanic ashes. These software solve equations for advection, diffusion and sedimentation of particles in two or three dimensions and will be applied to the main and most widespread tephra, for which a discrete number of outcrops are known in both proximal and distal areas.
