The spa tourism valorize the natural resources with balneary potential (mineral, mineral-thermal water, mofettes, mud therapy, salt mines, aerosols), under a special arrangement of space (infrastructure and appropriate types of treatment facilities) and the presence of qualified medical personnel.
Among various approaches, investigations on [CO.sub.2]-rich locations (i.e., emissions occurring in vents or mofettes), have been selected as specifically attractive introducing a minimum of experimental intervention to these "natural laboratories".
Among them, one should mention contacts of several geological units in the basement, deep faults, granitic massifs, extensive Tertiary sedimentary basins with lignite deposits, Tertiary and Quaternary volcanism, mineral and thermal springs, dry gas vents (mofettes), contrast gravity anomalies, and earthquake swarms in the western part of the rift (Horalek et al., 2000).
