The Geological Society of Japan 120th Annual Meeting, International Symposium
"Circum-Pacific Ophiolites: Subduction, Accretion, and Mantle Processes" has been held in the Kawauchi Campus of Tohoku University in the morning of 16 Sep. 2013. The invited speakers comprised Y. Dilek, R. Harris, S.D. Sokolov, S. Arai, T.Tsujimori, and the conveners (S. Miyashita and I) also gave their talks. The symposium was successful with a large audience (about 100) and lively discussions. The associated field trip to the Hayachine-Miyamori ophiolite and Motai high-pressure metamorphic belt (Kitakami Mountains, Iwate Prefecture; Guides: K. Ozawa, H. Maekawa and I) was also successfully carried out in 17-18 Sep. with 29 participants under the clear sky after passing of Typhoon #18.
