| Outline of Final Research Achievements |
We investigate Be isotopic ratios for Daisen, Sambe, Aonoyama volcanic rocks in the southwest Japan arc, and Iwate and Kanpu volcanic rocks in the northeast Japan. Be isotopic ratios (10Be/9Be) for the volcanic rocks from Daisen, Sambe, and Aonoyama were 0.3--17 x 10^-13, indicate the incorporation of a component derived from subducted sediments in the southwest Japan arc magmas. However, our result of Iwate volcano was extremely lower than those from previous results, further investigation will be necessary for precise determination of Be isotopic ratios.
