英文摘要	Measurements of the long-lived Kr-81 and Cl-36 radioisotopes in groundwater from the Negev Desert (Israel) were used to assess the Cl-36/Cl input ratios and Cl- contents for paleorecharge into the Nubian Sandstone Aquifer (NSA). The reconstructed Cl- content of the recharge flux was on the order of 300-400 mg/L. An initial Cl-36/Cl ratio of 50 x 10(-15) was assessed for the groundwater replenishment in the Negev Desert since the late Pleistocene, in agreement with the Cl-36/Cl ratios in recent local rainwater. This is despite possible changes in the climatic conditions and the Cl-36 production rates in the atmosphere over this timeframe. This similarity in values is explained by the major role played by the erosion and weathering of near-surface materials in the desert environment that dominate the hydrochemistry of rains, floods, and the consequent groundwater recharge. Spatial variation in the reconstructed initial Cl-36/Cl ratio is accounted for by the differences in the mineral aerosol sources for specific recharge areas of the NSA. Accordingly, regional variations in the Cl-36/Cl input in groundwater reservoirs surrounding the Mediterranean Sea indicate various processes that govern the Cl-36/Cl system. Finally, the results of this study highlight the great advantage of integrating Kr-81 age information in evaluating the initial Cl-36/Cl and Cl- input, which is essential for the calibration of Cl-36 radioisotope as an available long-term dating tool for a given basin.
