| Abstract: | Fresh and mineral waters from the eastern margin of the Suez Rift Valley are described. They include a fair number of sources that resemble the mineral waters in the Jordan Rift Valley. The term Tiberias-Farun water is thus suggested to describe them. They are characterized compositionally by Cl > Na (in equiv.), the presence of NaCl and MgCl2, a Cl/Br ratio (by weight) around 150, elevated radium and H2S content, elevated temperature, a light stable-isotope composition and high carbon-14 age. The Tiberias-Farun waters are suggested to have originated from entrapped seawater that gradually changed in composition by interaction with aquifer rocks. Such changes were demonstrated to take place in the laboratory experiments. |
