Abstract

Experriments of cation leaching (Na<sup>+</sup>, K<sup>+</sup>, Ca<sup>2+</sup>, and Mg<sup>2+</sup>) from rocks to CO<sub>2</sub> saturated water were carried out to clarify the relation between water quality and surrounding rocks. Rock samples use were: 15 granite, 5 rhyolite, 15 andesite, 6 granodiorite, 13 basalt, 6 tuff, 3 mudstone, 6 sandstone, 19 feldspar, and 7 mica samples. On the trilinear diagram, results of granite, rhylite, and basalt agreed with water quality in respective rock areas. The rocks, therefore, affect the quality of water nearby. Alkali feldsper in granite and rhyolite, and plagioclase in olivine basalt readily dissolved in the CO<sub>2</sub> saturated water. The quality of ground and stream water depends on the ratio of cations leached into water from those feldspars.
