Abstract
Sabalan geothermal area is located on the northwestern portion of Sabalan volcano, approximately 16 km southeastern of Meshkinshahr city, in the province of Ardebil, NW- Iran. Chemical analyses of hot springs waters from the Mouil Valley on the northwest flank of Mt. Sabalan are presented.
The chemical characteristics of the hot springs were evaluated using the Cl-SO4-HCO3, Cl-Li-B and Na-K-Mg triangular diagrams. According to these ternary diagrams the hot springs from Gheynarge, Ilando, Malek-su and Khosrov-su typical Cl-SO4- waters, Mouil hot spring is acid SO4 type. Waters from studied area are not equilibrated with rock. Monitoring of chemical composition (Cl-, SO42-, Mg2+, Na+ and SiO2) for Gheynarge and Ilando hot spring has been carried out since 1997 to 2008. The results shown that there are no changes or the changes are negligible.
