英文摘要: Abstract(#br)Total and continuing denudation rates were estimated using cosmogenic nuclides and intensive field observations of sediment transport in two small basins (C3 and S3) from the Ashio Mountains, Japan. The C3 basin underlain by Triassic bedded chert, while the S3 basin has evolved in altered Jurassic sandstone-shale. Continuing denudation rates were estimated from the records of coarse sediment transport and stream discharge for 6 years (2004–2009), soil grain-size distribution, and dissolved load in stream water. A debris flow was observed and the volume was measured in C3 (chert). Concentrations of cosmogenic 10 Be and 26 Al in fluvial sand were measured to determine spatially-averaged total denudation rates for these basins on the basis of steady-state assumption. Continuing...
