- •
Groundwaters in Laxemar are the result of complex mixing and water–rock interactions.
- •
Climatic changes induced the input of different recharge waters generating a salinity gradient.
- •
Disequilibrium states imposed by mixing have conditioned the water–rock interaction.
- •
Main reactions include gypsum and calcite dissolution/precipitation and cation exchange.
