dc.description.abstractA large-scale landslide took place at a southeastern slope of Mt. Jizuki, Nagano Prefecture, on July 26, 1985. It has been said that landslide is closely related to the hydrological and hy-drogeochemical nature of groundwater involved.To investigate the weathering mechanism and the origin of groundwater, we collected andanalyzed water samples from the large-scale landslide area. The following facts can be pointedout: (1) weater-rock interaction is remarkably active in the landslide area, (2) most of the watersfrom the landslide area are in equilibrium with Na-montmorillonite (3) immediately after the land-slide occurred bicarbonate and sodium ions are dominant, but sulfate and sodium ions becomedominant with time, and (4) groundwater passing through horizontally drilled holes does noteffectively drain off to stabilize a slope in the landslide area.And our hypothesis on the mechanism for the formation of sodium sulfate type water is alsopresented.en
