内容記述 | Rain waters collected on the roof of Research Institute for Hazards in Snowy Areas, Niigata University between the period March 1999 to January 2000 were analyzed for the ^<87>Sr/^<86>Sr ratio, Rb and Sr concentrations and oxygen isotopic ratio. The ^<87>Sr/^<85>Sr ratios of rain waters range from 0.70658 to 0.71051. Most rain waters are close to sea water in the ^<87>Sr/^<86>Sr ratio. This indicates that Sr in most rain waters originated from sea water. The high Sr isotopic ratios (>0.710), in spring and winter, may be affected by eolian dust. In addition, strong seasonal wind through beach carries sands which may also affect Sr isotopic ratios of rain water in winter. Sea water samples were collected at five beaches in Niigata Prefecture. These ^<87>Sr/^<86>Sr ratios are in narrow range from 0.70915 to 0.70917, and are equivalent to average of sea water in the world (0.709177). This supports homogeneity of sea water in Sr isotopic ratio. The δ^<18>O values of rain waters range from -17.17 to +0.23‰, and do not relate to theoretical seasonal variation. | |||||
