Description: Das Projekt "Sub project: Characterization of the Campi Flegrei fluid regime in time and space to understand the interplay between fluids/gases and volcanic/seismic processes" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum durchgeführt. This study intends to investigate gases and fluids from the Campi Flegrei caldera at depth and at the surface within the framework of the Campi Flegrei Deep Drilling Project (CFDDP) of ICDP to gain new insights into the evolution of the fluid regime in time and space and to understand the interplay between fluids at depth and volcanic/seismic processes as well as fluid migration and mixing processes. On-line geochemical analysis of gases will be performed (i) from returning drill mud during drilling a 3,5 km deep hole, (ii) from a shallow (500m) well and (iii) at the surface from volcanic gas discharges. Stable isotope and noble gas isotope analysis will be conducted on gas samples from all phases. During drilling, gas is extracted from returning drill-mud and continuously analyzed in real time to reveal information on the molecular composition and distribution of gases at depth. Studies of noble gases and stable isotopes from off-line mud gas samples will deliver information on the origin of these gases. Results from studies on drill mud gas will characterize the Campi Flegrei fluid regime in space. The monitoring of gases and fluids from a shallow well identifies short- and long-term variation in the fluid and gas composition in time to understand the temporal evolution of the Campi Flegrei magmatic system. Geochemical monitoring of volcanic gas emissions will help to assess the input of shallow and deep fluids to the fluid regime and migration processes of fluids from depth to the surface. On-line monitoring of volcanic gas from a vent in the fumarole field of Pisciarelli at the eastern outer flank of the Solfatara volcano has already been started.
