In order to study the migration of strontium and the occurrence characteristics of mineral water in Dushan area of Eastern Hebei Province, through collecting data and hydrogeological investigation, using rock-mineral identification test and PHREEQC model to determine the mineral composition, and analyzing the migration path of strontium, it is considered that the content of Strontium in the deep tectonic crack water in Dushan area is mainly affected by the vertical groundwater supply, while the horizontal groundwater runoff has little influence on the content of strontium. Based on this, the distribution characteristics of strontium mineral water are analyzed, and the occurrence characteristics of mineral water are discussed in combination with the controlled source audio magnetotelluric method and radon measurement, which are: (1) the high content of strontium is the material basis in the study area, and strontium can be migrated, differentiated and enriched with calcium plasma through chemical changes; (2) the fracture structure is relatively developed in Dushan area, which provides mineral water with Storage space and runoff channel; (3) under the specific environment of high temperature and high pressure, strontium is continuously transported and enriched to the deep underground along the fracture zone to form strontium mineral water body, affected by the long-term runoff of groundwater and the dissolution, filtration, mixing, hydrolysis and metamorphism with rocks.
