New paper about the apparent water ages in the South German Molasse Basin (SGMB) using 14C-DOC and 81Kr is published in Jounal of Hydrology

Here we reported ¹⁴C-DOC and ⁸¹Kr groundwater dating results together with hydrochemical data, stable
water isotopes, noble gases and out-diffusion experiments that indicate that the thermal groundwater
consists of at least two groundwater sources: a formerly unknown young groundwater component with
apparent water ages between around 10,000 and 19,000 a and an old groundwater component, which shows an
apparent water age of up to approximately 300, 000 a. The results of the performed out-diffusion experiments with
core material from the Upper Jurassic aquifer (UJA) suggest that diffusion processes between rock
matrix water and more mobile fracture water represent a controlling mechanism for groundwater flow
and the observed extended apparent groundwater ages within the UJA.

Congrates to Thies for his nice piece of work!
