Isotope hydrological study with carbon-14 and argon-39 in the Bunter sandstones of the Saar region
Abstract
Argon-39, carbon-14 and other isotopes have been measured in a sandstone aquifer in the Saar region (Federal Republic of Germany) where already chemical and isotopic investigations had been carried out. From measurements of two samples showing no detectable 39Ar it was clear that subsurface production of 39Ar can be neglected in this aquifer. For the other three samples, the determination of isotope concentrations (including the usual corrections for the initial concentration of 14C) gave consistent results within the errors of determination and correction. The discussion of the results led to the conclusion that, in addition to 3H, 2H, 18O, 13C and 14C determinations, the 39Ar and 85Kr methods should be applied for isotope hydrological investigations. This is evident especially in systems where mixing of waters with different ages takes place. First steps in investigations of the subsurface production of 39Ar using neutrons for irradiating core material, as well as in elaborating a computer program for calculating isotope production (e.g. 36CI and 37Ar) in parallel with 39Ar, are briefly mentioned.
