Gas geochemistry has been proven to be a reliable and simple technique to apply, at different scales, to many geological scenarios (Annunziatellis et al., 2003; Lewicki et al., 2003; Baubron et al., 2002; De Gregorio et al., 2002; Ciotoli et al., 1998; Ciotoli et al., 1999; Lombardi et al., 1996; Hickman et al., 1995; Duddridge et al., 1991; Durrance and Gregory, 1988; Eremeev et al., 1973). The importance of fluid geochemistry is rooted in the fact that the Earth is an open system and that fluid-releasing crustal phenomena are the major means for the exchange of matter and energy at different depths. As such, fluid-releasing channels like active faults and fractures are actually a ‘‘window’’ on subterranean physical and chemical variations (Ciotoli et al., 2007). The study of spatial distribution of soil gas anomalies at the surface, can give important and interesting information on the origin and processes involving deep and superficial gas species. This information can be applied and studied in different frameworks, for example: I) seismic zonation, examining, at the surface, anomalous concentrations of deep gas species that upraise throughout preferential pathways (faults and/or fractures). Soil gas distributions can be directly linked to the evolution of the stress regime and gases migrate preferentially through fractured zones but only along pathways whose permeability has been enhanced by seismic activity and/or through areas of brittle deformation. II) Environmental protection, such as the monitoring of naturally occurring toxic gases to highlight zones with high health risks for humans. The presence of magmatic chambers can cause an accumulation of gases in the subsurface and local structural features can favour high degassing phenomena. These events are particularly dangerous in populated areas and it is necessary to build risk maps to define the potential health hazard in terms of both short-term and long-term risk. III) Radionuclide migration, both in the pollution assessment from abandoned uranium mines and in the study of high-level radioactive-waste isolation systems. The main approach is to study the natural migration of radiogenic particles or elements throughout clay formations that are considered an excellent isolation and sealing material due to their ability to immobilize water and other substance over geological timescales. The evaluation of long-term behaviour of clays under normal and extreme conditions is still the main topic 9
