Mixing models and evaluation of SiO2 contents of warm-water manifestations in the Jordan-Dead Sea Rift Valley indicate that these waters are fed by aquifers with estimated temperatures of up to 68??C. These calculations and Na/K ratios, concentrations of Na, K and Ca, concentrations of atmospheric Ne, Ar, Kr and Xe; and concentrations of the stable hydrogen and oxygen isotopes all indicate below-boiling temperatures. No indications are available for the existence of above-boiling geothermal systems in the Jordan Rift Valley. Slightly higher than observed temperatures are concluded for a deep component at the springs of Hammat Gader (67??C), Gofra (68??C), the Russian Garden (40??C), and the Yesha well (53-65??C). These temperatures may encourage further developments for spas and bathing installations and, to a limited extent, for space heating, but are not favorable for geothermal power generation. ?? 1980.
