(Ferraria). At springs occurring in the basal complex the dynamics of tide determines
relevant oscillation of total dissolved solids and of the piezometric level.
The NaCl facies of the waters are directly dependent of sea water mixing processes
and the CO2 total content as deep origin. This CO2-rich acidizing water,
promotes rock leaching contributing to high contents of silica, iron, nickel and
manganese, among others dissolved species.
Flow from primitive exploitation works (dug well located inside the Thermal
Bath of Carapacho and dug well accessible by a gallery, and destroyed by the 1998
earthquake, at Varadouro)
Conclusions
Those mineral waters have electrical conductivities from 6 to 47 mS/cm and
temperatures from 35ºC (Varadouro old spring), to 41ºC (Carapacho) and 62ºC
(Ferraria). At springs occurring in the basal complex the dynamics of tide determines
relevant oscillation of total dissolved solids and of the piezometric level.
