Outline of Final Research Achievements

Regarding the natural historical specimens damaged by the tsunami in the Great East Japan Earthquake, specimen rescue projects were implemented, and many natural historical specimens were stabilized. As a preliminary and experimental study to prepare for the next earthquake / tsunami disaster, this research was carried out with the objective of establishing the stabilization treatment of the soft rock material of the geological specimen assuming the damage of the tsunami.
For experiment of soft rock specimens, geological specimens were collected from late Cenozoic strata in several region of Japan.　In the experiment, the geological specimen was cut into blocks and immersed in ultrapure water and artificial seawater, respectively. Every week, the observation of the surface and the dissolved element concentration of the immersed water were analyzed.
