Rates of Rock Property Changes due to Weathering : Sandstone Gravel in Fluvial Terrace Deposits in the Miyazaki Plain

摘要

Temporal changes in colour, mineralogical, chemical, physical and mechanical properties due to weathering during 350,000 years were examined using sandstone gravel in fluvial terrance deposits with a known energence time which were distributed in the Miyazaki Plain, South Kyushu.
