Abstract
Mineral waters from the depths of the Tanzawa mountains are briefly characterized as having high pH values ranging from 9.5 to 10.0. The origin of the mineral waters is discussed in relation to zeolites extensively developed along fractures and joints throughout the Tanzawa mountains. Thermal water (33/sup 0/C) of the Nakagawa spa may be regarded as evidence of past strong geothermal activity. Measurement of geothermal gradient at two locations, Nakagawa (12.6/sup 0/C/100m) and Higashi-sawa (5.55/sup 0/C/100m) also supports the presence of weak thermal activity in the depths. Chemical analysis of the mineral waters indicates that the pH of the system is chiefly controlled by the ratio of CO/sub 3//sup - -//HCO/sub 3//sup -/. The following reaction with zeolites promotes an increase of the pH: HCO/sub 3//sup -/ + (Ca/Na) zeolites reversible CO/sub 3//sup - -/ + H-type (Ca/Na) zeolites + (Ca/sup + +//Na/sup +/).
