| Outline of Final Research Achievements |
This study deals with the combination phenomena of reaction and deformation in rocks. The targets are metasomatism found in serpentinite melange intercalated to high-pressure low-temperature metamorphic belts. Mass balance analysis using the isocon method was applied to estimate the volume changes of fluid and solid phases and the changes of pore-fluid pressure during metasomatism. As a result, the combination phenomena of reaction and deformation were classified into three types: (A) hydraulic fracturing due to increasing pore fluid pressure, (B) reaction-enhanced ductility due to decreasing pore fluid pressure, and (C) decrease of permeability due to increasing solid volume.
