Isótopos ambientales en las aguas subterráneas del macizo ígneo-metamórfico del Sistema Central (Cuenca del Alberche)

Abstract

The results of isotopic analyses - deuterium , oxygen-18 and tritium - are discussed for ground water 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 C03H-Na with reduced forms of sulphur waters can be related with medium or regional flows of meteoric waters in the cristalline body and the same can be interpreted from their tritium contents. There are not enough data to dismiss other sources
