Abstract (in english)
   The studied area of the Oberpfalz and Oberfranken with its Tertiary Basins, basaltic volcanites and mineral springs is general considered as Bavarian part of the Eger-(Ohře-)Rift. The gas composition of the gas phase of these mineral springs was analysed, as well as the delta13C and 3He/4He isotope composition. Additionally, the gas flux and water discharge were measured in order to calculate isotope mass balances. As expected, the geochemical characterisation of these gases is identical with those on the Czech part of the Eger Rift: in the Oberpfalz and Oberfranken there also occur nearly pure CO2 gases with high proportions of mantle-derived helium up to R/Ra values of 3.5 and delta13C values of -3.3 per mille. The distribution pattern of gas flux and gas composition, i.e. the pattern of the migration paths of the magmatic gases reflects the tectonic structure, i.e. the course of the Eger Rift main faults.
   Consequently it is possible to trace the extension of the Erzgebirge main fault with the line of Bavarian mineral springs of Hohenberg, Kothigenbibersbach and Bad Alexandersbad. Likewise, the extension of the Litoměřice deep fault can be seen in the migration path of the springs of Kondrau and Wiesau. Moreover, the narrowing of the Eger Rift by younger NNW-striking faults to the west already observable on the Czech side continues in Bavaria
