Uranium disequilibrium as a hydrological aid in studying the salinization processes in the Southeastern Coastal Plain of Israel

Research output: Contribution to journalArticlepeer-review

Abstract

Saline waters, of unknown origin, have been encountered in the basal portions of the phreatic Coastal Plain aquifer of Israel. 234U/238U disequilibrium was used to trace their origin to the evaporate layers within the Saqiye aquiclude, the most saline, and the warmest (up to 42 °C) waters are also those that have the highest uranium concentrations combined with low 234U/238U activity ratios, derived as the ascending brines traverse underlying uranium-rich Senonian phosphorites, in secular equilibrium along fault conduits.
