Outline of Final Research Achievements

Deformation experiments plays important role to understand the rheological properties and hence deformation at high pressure is a key for mantle dynamics. We developed high pressure deformation by adding the rotational deformation device to the conventional diamond anvil. Due to this development, we largely expanded the pressure range to the deep lower mantle condition from the condition of the top of lower mantle. Deformation test by using the present device at room temperature and ~40 GPa suggests that this device is useful for the deformation at high pressure.
