Abstract

To examine the rate of chemical weathering, field experiments using microweight-loss techniques were carried out. Two kinds of porous rhyolite forming lava domes in Kozu-shima Island were selected : a younger rock (weathering period is 2.6 ka) and an older rock (20ka). Both rocks seem to have been very similar in their initial composition and structure. They have, however, different properties in the present depending on the differences in weathering period. The results show that older rock has a higher rate of chemical weathering than in younger rock
