摘要: Abstract A set of analytical data from the Espadan–Calderona Triassic Domain aquifers was processed using hierarchical agglomerative cluster analysis (HCA) and principal component (PCA), to achieve a quantitative independent approach investigate characteristics groundwater composition possible differences between flows (Spain). Mineralization in series has led presence several metals metalloids groundwater, including As, Mn, Fe U. These are associated with fresher bicarbonate groundwaters, characterized by lower Sr/Ba ratios. Levels containing sulfate evaporitic salt, which interbedded through series, seem exert strong influence on chemistry calcium facies high Sr concentration The application multivariate statistical techniques interpretation results allows differentiation types occurring identification role number minor or trace elements their ratios that can be treated as hydrogeochemical tracers. With them it correlate different recharge waters tectonic morphology Domain.
