 note = {The ^<87>Sr/^<86>Sr ratio, Rb and Sr concentrations were determined in geothermal waters obtained from Deyu, Murasugi, Matsunoyama, Ryugakubo, Matsushiro and Otari hot springs. The Sr isotopic ratios of these geothermal waters are within the range 0.7046-0.7075. The soluble Sr in geothermal waters from Matsunoyama and Matsushiro hot springs are derived from fossil sea water and host rocks. In Deyu, Murasugi and Otari hot springs, Sr in respective host rocks (especially plagioclase) are dissolved in meteoric geothermal waters.},
