• The results of isotopic analyses - deuterium, oxygen-18 and tritium - are discussed far groundwater samples obtained from severals wells and springs with different chemical types, located in the crystalline basin of the Alberche river. The results agree with the hypothesis that both saline and CO3H-Na with reduced forms of sulphur waters can be related with medium or regional f/ows of meteoric waters in the crista/fine body and the same can be interpreted from their tritium contents. There are not enough data to dismiss other sources.
