| Research Abstract |
Stable isotope compositions of stalagmites and tufas were analyzed for high-resolution paleoclimatic records during late Pleistocene and Holocene, which are fundamental for predicting the climate changes of the warming Earth. The analyses revealed new aspects on the Japanese terrestrial climate from two stalagmite localities. First, analytical results of the specimen from Jinseki-Kogen(Hiroshima Prefecture) indicates temporal correspondence to the global changes during the post-glacial warming, which contradict to the previous study on the lake deposits in Fukui Prefecture. Second, the results of the specimen from Itoigawa(Niigata Prefecture) showed that the Holocene snowfall intensity was positively correlated with the winter Asian Monsoon and sea-surface temperature of the Japan Sea.
