Hydrothermal resources and their effect on quality of the thermomineral springs in Sabalan area-Ardabil Province,Iran
Hydrothermal resources and the thermomineral springs in the Ardabil region are genetically related to volcanic activity in the Sabalan Complex.
A relatively dense faulting network in the region has created a hydraulic connection between geothermal resource and thermomineral springs. Water quality in these springs is strongly depended on the physico-chemical nature of subsurface hydrothermal system.
Chemical analysis of water samples from Sabalan springs proved that: the surface geothermal features can be categorized into three fallowing groups:
1. Hot and neutralized springs, connected to the primary geothermal fluids. These are strongly dominated by high concentration.
2. Group of springs rich in and , most probably affect by lateral flow of diluted hydrothermal fluids.
3. Final group of springs that are only related to the surface meteoric water (precipitation), and they lack any hydrothermal significance.
