Description
Short-term dissolution rate of limestone in a doline on Akiyoshidai Plateau was estimated from 3-year field weathering experiment and hydrological observation. Limestone tablets were buried in soil at 4 sites for depth of 50 cm or 15 cm. The result indicated that the duration of saturated soil moisture condition controls dissolution rate of limestone tablet. The estimated annual dissolution rate at the zone of high soil moisture content above soil-bedrock boundary was 356 g/m2•yr, which is slightly larger than maximum long-term denudation rate (63 – 256 g/m2•yr) inferred from cosmogenic radionuclide analysis.
