A symposium on ophiolites, greenstones and ocean-floor rocks in Japan and Far East Russia will be held at the lecture room of the Ocean Research Institute, the University of Tokyo on Saturday, March 4, 2006. The program is shown below. This symposium is a project in the Japanese-Russian co-operative research titled "Origin of Paleozoic meta-ophiolites and Mesozoic accretionary complexes in the circum-Pacific orogenic belt of the Koryak Mountains" (Leaders; A. Ishiwatari (Japan) and S. D. Sokolov (Russia)), which is supported by JSPS of Japan and RFBR of Russia. We welcome participation of those who are interested in geology, petrology, geochemistry and tectonics related to these rocks.

To find the way to the Ocean Research Institute, please see the following address.


We thank Prof. Teruaki Ishii of Ocean Research Institute for the arrangement of this symposium.
