Hydrochemical characterization of geothermal and non-geothermal waters from Wadi Fatima, western Saudi Arabia

The present study was conducted in the Wadi Fatima catchment in western Saudi Arabia with the primary objective of finding the major hydrochemical differences among geothermal and non-geothermal groundwater samples. Based on the dissolved-silica content of 124 groundwater samples, the chalcedony geo...
