Important results obtained by this study are summarized as follows.(1) Analytical study on hydrothermally altered rocks associated with hydrothermal are deposits ( kuroko deposits) clarified geochemical behavior of rare earth elements during the hydrothermal alteration.(2) Analytical study on base metals (i. e. Cr etc) and rare earth elements contaminated soils, river sediments and sands and experimental study on the extraction and water-rocks interaction clarified the concentrations and chemical states of base metal and rare earth elements.(3) Groundwater chemistry was interpreted based on analytical and thermo chemical data and water-rock interaction experiments. Computer simulation was also used for its interpretation. Water-rock interaction experiments and simulations were also applied to CO_2 underground sequestration and CO_2 capacity in aquifer and CO_2 behavior in underground were estimated and clarified.(4) Secondary minerals( clay minerals and carbonates) in sedimentary rocks were analyzed for base metals and rare earth elements and the factors controlling the concentrations of these elements ( ionic radii, charge, electronegativity etc) were considered. The retardation of radioactive elements released from nuclear waste was considered. The method preventing the release of base metal elements from contaminated soils was considered.(5) The simulation based on kinetics-fluid flow coupling model was carried out to interpret groundwater geochemistry and estimate residence time of groundwater in Mt. Fuji area.

（1）对与水热相关的水热改变的岩石的分析研究总结了矿床（kuroko沉积物）是稀有地球元素在水热改变过程中的地球化学行为。相互作用阐明了碱金属和稀土元素的浓度和化学状态。（3）根据分析和热化学数据以及水摇滚相互作用实验来解释地下水化学。计算机模拟也用于解释。估计并阐明了地下含水层和co_2行为的CO_2地下隔离和co_2的能力。（4）在沉积岩石中估算了二级矿物质（粘土矿物和碳酸盐）的含水层和co_2的能力。（4）对这些碱金属和稀土元素的浓度分析了沉积岩石中的二次矿物质（粘土矿物和碳酸盐）。考虑了从核废料释放的放射性元件的延迟。 （5）基于动力学流体流量偶联模型的模拟被考虑以解释地下水地球化学并估算了富吉地区地下水的停留时间。
