Isotopic and hydrochemical data as indicators of recharge areas, flow paths and water–rock interaction in the Caldas da Rainha–Quinta das Janelas thermomineral carbonate rock aquif
Abstract:

An updated conceptual circulation model for the Caldas da Rainha and Quinta das Janelas thermomineralwaters was developed. These thermomineral waters (T _ 33 _C) are related to a huge syncline ascribed tothe regional flow paths. Two diapiric structures were responsible for the uplift and subsequent folding ofregional Jurassic carbonate rocks. Environmental isotopic (d2H and d18O) data indicates that the mainrecharge area of the thermomineral system is linked to the Jurassic limestones (Candeeiros Mountains,E border of the syncline). The thermomineral waters belong to the Cl–Na sulphurous-type, with a totalmineralization of about 3000 mg/L. The thermomineral aquifer system seems to be ‘‘isolated’’ fromanthropogenic contamination, which is typical for the local shallow groundwater systems, due to theexistence of impermeable layers composed of a series of loamy and detritic rocks of the Upper Jurassic.The presence of 3H in some thermomineral borehole waters, not accompanied by an increase in SO2_4 andNO_3 , could be ascribed to different underground flow paths and different mean residence time. Thed34S(SO4) and d18O(SO4) values of dissolved sulphate of groundwaters of the Caldas da Rainha Spas indicatethat the sulphate is the result of water–rock interaction with evaporitic rocks (e.g. gypsum and anhydrite)ascribed to the regional synclinal structure.
