Abstract

To examine temporal changes in rates of weathering of bedrock, weathering profiles were observed from the drill cores obtained at 24 sites on 3 levels of erosional marine terraces emerged in the period of 70 to 2,850 yrs B.P. in Boso Peninsula, Japan. The bedrock of terraces consists mainly of Tertiary sandstone and mudstone. The mode of deceleration in the weathering rates with time differs between mudstone and sandstone. Initially mudstone weathers faster than sandstone, but the mudstone weathering rate decreases more rapidly than sandstone, and after about 400 years, the sandstone rate exceeds that of mudstone
