There are a lot of high-Sr granite in the north margin of north China craton, however, the occurrence of strontium type mineral water in the surrounding areas is rarely studied. In this paper, the distribution and formation mechanism of strontium mineral water in the surrounding area of Dushan rock mass which as a typical high-Sr granite were analyzed for the first time by hydrogeological survey, water sample collection and laboratory analysis. At the same time, the water bodies in the surrounding areas of four high strontium granite bodies such as Shouwangfen, Nian-ziyu, Xiao-sigou and Yangzhangzi rock mass were investigated and sampled to verify the distribution law of strontium type mineral water. The results show that Sr element is contained in all the water bodies around the Dushan rock mass, and the closer it is to the rock mass, the higher the strontium content in the water sample is, up to 13.81 mg/L, far higher than the other strontium-containing mineral water in China. but the strontium content of the water sample which in the sandstone of Ch is the lowest. In the horizontal, the Sr-type mineral water in the pore water is distributed mainly along both the NE-SW fault zone and the southern compression zone, whereas that in the fissure water and the tectonic bedrock fissure water is distributed only along the NE-SW fault zone. In the vertical, the Sr-type content increases with the sequence of the pore water, the weathering fissure water of network bedrock and the fissure water of tectonic bedrock. The high Sr granite of this area provides the source of Sr content for the formation of Sr-type mineral water. The continuous dissolution of Sr in stratum during the runoff of groundwater is the inherent mechanism. Hydraulic connection may exist in the three vertical aquifers and Sr content may accumulate during the infiltration process. The stable quality and quantity of the fissure water of deep tectonic bedrock suggest the great value for development and utilization. The distribution of strontium mineral water in the surrounding areas of the other four high strontium granitic rocks shows a similar pattern to that of the Dushan rock mass area. This study reveals the occurrence law of strontium mineral water in high-Sr granite region for the first time，and the results provide reference for the development and utilization of high quality strontium mineral water resources in many high-Sr granites.
