Abstract: This the first work to verify the rare iodine-bearing natural drinking mineral water named “Sino iodine-bearings mineralwater”. The study shows that this mineralwater was formed in a Cepozoic fault-bounded basin with weakly basic and oxidizing hydrogeochemical condition. It is the product of the reaction between the groundwater end the continental clastic sediments. The high-quality water belongs to the iodine-bearing soda type mineralwater with slightly higher concentration of fluorine. In order to exploit the water reasonably, the electronic percolation technique is suggested to be used co reduce the fluorine during large-scale production.
