Abstract :
Amethod is proposed, for low-temperature geothermal systems, for calculating the aquifer temperature and
relative proportions of mixed thermal and shallowgroundwaters from carbonate-evaporite environments. The
fluid is assumed to be in chemical equilibrium with anhydrite and chalcedony in the aquifer, and mixed with
diluted waters during its ascent. An attempt has been made to establish a relationship between reservoir temperature,
the aqueous sulfate and silica contents of the mixed fluid, the proportion of the thermal end-member
and the temperature of the adiabatic mixture. The method calculates mineral solubilities in the field context,
calibrated on representative thermal springs. The method also considers the effects of conductive cooling.
