Numerical modelling of ion exchange reactions in sedimentary rocks and its application to natural systems

Ion exchange reactions in sedimentary rocks at Horonobe were numerically investigated. In order to simulate complex exchange reactions during freshening process of fossil seawater, active fraction model was adopted. Our calculation revealed Na-desorption and Ca-adsorption will occur when exchange parameters of the rocks are assumed to be those of soils. This result is consistent with observed depth profile of bulk composition.
