Sr isotopic signatures of Portuguese bottled mineral waters and their relationships with the geological setting Assinaturas isotópicas de Sr em águas minerais de Portugal e sua relação com o enquadramento geológico

This work presents the 87 Sr/ 86 Sr isotope compositions of nine samples of bottled waters from several regions of Portuguese mainland. The Sr isotopic variability displayed by the analysed waters is strongly correlated with the age and mineralogical composition of the aquifer source rocks, suggesting that the 87 Sr/ 86 Sr isotope signatures of these mineral
