Resumen:
In order to understand the geological and hydrogeological processes
influencing the hydrogeochemical behavior of the Cerro Prieto Geothermal
Field (CP) aquifer, Mexico, a characterization of the water samples
collected from geothermal wells was carried out. Different hydrochemical
diagrams were used to evaluate brine evolution of the aquifer. To
determine pressure conditions at depth, a calculation was performed
using hydrostatic and lithostatic properties from CP, considering
geological characteristics of the study area, and theoretical
information about some basin environments. Groundwater shows
hydrogeochemical and geological evidences of the diagenetic evolution
that indicate overpressure conditions. Some physical, chemical,
textural, and mineralogical properties reported in the lithological
column from CP are explained understanding the evolutionary process of
the sedimentary material that composes the aquifer.
