Paleohydrological mixing portions in one deep borehole at the Swedish Aspo Hard Rock Laboratory
- GeoPoint AB, Sollentuna (Sweden)
A borehole 1700.5 m deep near the AESPOE Hard Rock Laboratory represents the deepest borehole drilled for the project. In order to establish the paleohydrological mixing portions in the present water, a mixing model was constructed using Principal Component Analysis. This multivariate method used both conservative and non-conservative tracers. The mixing model can describe how large portions of a particular type of water are needed in order to explain the chemical composition of the observed water. Six end-members were identified which are believed to represent waters that interact in different degrees in the sampling area. Mixing ratios were calculated for each end-member at various borehole depths. The multivariate calculation technique established the tracers of paleohydrological water in the borehole with greater resolution than univariate analysis.
