| Research Abstract |
This year is the final year of the research project and many results were come out and some of them were published in the international journals. The most basic equipment for this project, the Raman spectroscopy, could do both on DAC and thin sections, and this is the first aim for geoscience. It could detect the high pressure phase of gas hydrate, and many natural minerals in micrometer scale under transparent microscope. In geoscientific results, we found many new observations, among which the pseudotachylyte from the ancient plate boundary fault was the most profound result. Another interesting result is that we found bimodal fluid flows in the Ordovician accretionary prism boundary fault in Scotland. Some of the pelagic to terrigenous sediments were analyzed from micrometer scale before and after entering to the accretionary prisms. All of these results were displayed in the international meetings or published in journals. In addition we did an extensive study on the plate boundary faults and related deformation and fluid flow in the Mienoka ophiolite. We elucidated several stages from the deformed basaltic rocks. As above, our final goal was accomplished
