Most of the mineral water sources in this area, including those in the Laoshan and Kunyu Mountains, occur in Mesozoic granites. The groundwater and mineral waters contain metasilicic acid and strontium but the latter is potable. Mineral water is also found in the Jiaolai Basin, hosting in the basalts of the Wangshi group in Anjiagou Village, Jiaozhou City. The rapeutic groundwater, however, is rarely found in this area, except for the recent discovery of CO:-Li-Sr rich therapeutic and potable groundwater, which is reported in this study.展开更多
