A geometrical method for quantifying endmembers' fractions in three?component groundwater mixing

We present a new geometrical method capable of quantifying and illustrating the outcomes three-component mixing dynamics. In scenario, classical algebraic equations endmember analysis (EMMA) can be used to quantify contributions from each fraction. Three-component natural waters, either in an element–element plot or by using EMMA subspace is described triangular shaped distribution sample points where placed on apex, while side corresponds function two endmembers at considering third endmembers' contribution equal zero. Along side, theoretical fractions computed mass balance equations. Samples with three will inside triangle, homogeneous barycentric coordinate projections projected onto sides. The geochemistry observed mineralized Ferrarelle aquifer system (southern Italy) results groundwater, diagnostic geochemical compositions. defined boundary conditions allow us parameterize validate procedures for modelling mixing, including selection suitable tracers.
