摘要:Abstract(#br)This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic 36 Cl in China. Concentrations of natural Cl and in-situ cosmogenic 36 Cl in bare carbonates from Guizhou karst areas were measured with isotope dilution by a...

摘要:...(#br)In this study we investigate these effects by exploring the spatial distribution and magnitude of denudation in the Hörnli region of the eastern Swiss Alpine Foreland in the present Interglacial. The area represents both domains in a relatively small area with largely...

摘要:Abstract(#br)This study quantifies the surface denudation rate of granitic regolith via the application of the in situ cosmogenic 26 Al and 10 Be depth profile in China. The concentration ranges of 26 Al and 10 Be in the quartz along the ~3-m granitic regolith profile in Qinhu...

摘要:Abstract(#br)The chemical weathering rate and atmospheric/soil CO 2 consumption of Paraná flood basalts in the Preto Stream basin, São Paulo State, Brazil, were evaluated using major elements as natural tracers. Surface and rain water samples were collected in 2006, and analy...

摘要:Abstract(#br)Quartz is widely used as a target mineral for determining watershed-averaged denudation rates because it is resistant to chemical weathering, geologically widespread, and has a well-constrained 10 Be production rate. However, quartz is not available in many landscape...

摘要:Abstract(#br)The relative importance of climatic and tectonic factors in driving rates of denudation in mountain ranges has long been debated, with both precipitation and rates of crustal uplift cited as first order controls in a variety of different mountainous settings. Few...

摘要:Abstract(#br)The denudation of landscapes is affected by temporal and spatial variations in tectonics, climate, and vegetation. However, deciphering the contributions of these different processes has proven challenging. In this study, cosmogenic nuclide-derived modern and pale...

摘要:Abstract(#br)The stream power law, expressed as E = KA m S n — where E is erosion rate [LT − 1 ], K is an erodibility coefficient [T − 1 L (1 − 2 m ) ], A is drainage area [L 2 ], S is channel gradient [L/L], and m and n are constants — is the most widely used m...

摘要:Abstract(#br)10 Be concentrations in stream sediments are commonly employed to calculate basin-averaged denudation rates. Such calculations assume that denudation is steady in time and that quartz is uniformly distributed in the watershed. The 10 Be concentrations in stream sedim...

摘要:Abstract(#br)Depth profiling of in situ-produced cosmogenic 10 Be and 26 Al was applied to estimate the rate of long-term denudation on actively uplifting hillcrests made of weakly consolidated sandstone in the Boso Peninsula, Japan. The nuclide concentration in the topmost me...
