Objective The purpose of this work programme is to carry out acomprehensive and multidisciplinary study of the sources,chemistry, behaviour and fluxes of volcanic/magmatic volatiles atEtna, in order to contribute to better understanding of the magmafeeding system and the eruptive dynamics of this volcano.Volatiles are studied in the both gas phases and the solidphases. For gas phases the following analyses are carried out inthis project: airborne gas flux measurements and plume sampling,analysis of radioactive and stable trace-metals in Etna's plume,infra-red remote analysis of plume gases, and improvement of Etnamonitoring by UV correlation spectrometry (COSPEC).These experimental approaches are utilized to provide informationabout crater plume emissions. In order to quantify the wholeenergy and volatile output from the volcano, and its temporalvariations, fumarolic and soil gas emissions are studied, withcomplementary actions: prospections, sampling for chemical andisotopic analysis, airborne mapping, automatic continuousmonitoring of CO2, Rn, H2, as well as meteorologicalhydrodynamic parameters.Various sophisticated analytical technics will be also used forchemical and mineralogical analysis of fumarolic sublimates:polarized microscopy, X-ray fluorescence, atomic absorption,scanning emission spectroscopy, ion probe, secondary ion massspectrometry. Data reduction and analysis will be done withavailable computing equipments.Concerning volatiles in lava, the following analyses will becarried out: geochemistry of trace-elements and major volatiles(H,S,Cl,F) in melt inclusions and matrix glasses (neutronactivation, nuclear (PIXE), electron and ionic microprobes, massspectrometry), abundances and isotopic composition of rare gases,carbon and oxygen, and vesicularity and volatile control on themodal composition of Etna lavas.The results of this project are expected to be: Quantitativeassessment of chemistry and total output of volatile emissionsfrom Etna: crater plume, fumaroles and sublimates, soilemanations, gaseous springs (major, minor and trace elements;stable and radioactive isotopic species). Identification andsurvey of their temporal variations with volcanic activity or/andgeophysical events; characterization of their spatialrelationships with the main structures of the edifice and thehydrological system. Chemical and isotopic characterization ofvolatiles in the magma source, of their fractionation duringmagma ascent, differentiation and degassing, and evaluation ofpossible interactions with the local crustal basement.Quantification of the volume, residence time and degassing modeof intrusive magma batches. Improvement of the geochemicalmonitoring of Etna.
