Micro-analytical investigations on Campi Flegrei pyroxene-hosted melt inclusions, H2O-CO2-S-melt and δD modelling

We attempt to reconstruct the architecture of the magmatic feeding system of the Campi Flegrei volcanic field, to shed light on the processes interplaying during magma evolution and ascent to the surface. To this aim, we provide chemical (major, trace and volatile elements) and isotopic (δD) data on melt inclusions from Campi Flegrei eruptions. The datadabase includes major and trace elements analyses of the host-clinopyroxene crystals, from the paper "The source-to-surface journey of volatile-flooded magmas: the archetypal case of the Campi Flegrei unrest caldera" by Ilenia Arienzo, Bruna Cariddi, Carlo Pelullo, Claudia D’Oriano, Etienne Deloule, Massimo D’Antonio, Roberto Moretti. Case studies are the Campanian Ignimbrite eruption (∼40 ka) and explosive events occurred during the last 5 kyrs of volcanic activity. The obtained data were modelled by using the non-ideal, composition-dependent model of Papale et al. (2006) and the CHOSETTO software (Moretti et al., 2003; Papale et al., 2022) implemented by accounting for magma crystallization.
