Closure experiment of gallery of MIU is planned to understand the recovery process of geological environments after the closure. Flooding test gallery and monitoring boreholes are designed at 500 m access gallery to observe recovery of water pressure, chemistry around cement and burial materials, rock stress. Evaluation of numerical analysis methods on hydraulic, chemical and mechanical change will be conducted based on the results of upcoming closure experiment.

We introduce apatite fission-track dating procedures conducted in the Tono Geoscience Center and a case study of the Yoro-Suzuka-Nunobiki mountains. Rapid cooling events associated with uplifting of the Suzuka Range were detected by using apatite fission-track inverse modelings. These results imply usefulness of the method to common Japanese mountains.

Microbial metabolism and the chemical buffer capacity in deep groundwater were estimated at Mizunami underground research laboratory. The results show that sulfate reducing bacteria uses hydrogen gas. The sulfate consumption rate is important index to infer the redox buffer capacity in deep underground.
