| Outline of Final Research Achievements |
Stalagmite is a suitable archive of the terrestrial paleo-climate in densely-populated temperate-subtropical areas. We have analyzed paleo-climatic proxies of the Japanese stalagmites collected from four sites with different climatic settings (Jinseki-kogen in Hiroshima Prefecture, Itoigawa in Niigata Prefecture, Gujo in Gifu Prefecture, and Taiki in Mie Prefecture). Our high-resolution records from these stalagmites reveals new aspects on the Japanese paleo-climetes; 1) stalagmite Sr isotopic ratio reflected from change in weathering processes in water reserve area, 2) oxygen isotope of the Itoigawa stalagmite recorded variation in winter monsoon intensity during Holocene, 3) the stalagmites from Gujo and Taiki sites recorded the millennial-scale Heinrich events, and 4) variation in the oxygen isotope of the Taiki stalagmite includes a fraction of the paleo-temperature change.
