摘要:Abstract(#br)Quantifying denudation rates along orogenic systems is crucial to understand how tectonics and climate interact with each other to create topography. Long-term mean denudation rates estimated from geologic data in the Ambato range (Sierras Pampeanas) is 0.34 mm/yr. ...

摘要:... The denudation of mountainous areas, source of this sedimentary supply, results from complex interactions between tectonics, climate, morphology, and rock erodibility. In this study, denudation rates from the present-day and ranging back to the Quaternary and the Pliocene a...

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 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:... In this study, spatial variations in catchment-wide denudation rates are reported from the Vakhsh River catchment with in situ-produced cosmogenic 10 Be and 26 Al of 22 samples from active river channels. Samples distributed along 140 km of the main Vakhsh River yield denudation rates...

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)Vegetation has long been hypothesized to influence the nature and rates of surface processes. We test the possible impact of vegetation and climate on denudation rates at orogen scale by taking advantage of a pronounced along-strike gradient in rainfall and vege...

摘要:... Here we present a landscape analysis using denudation rates derived from basin-averaged cosmogenic nuclide concentrations coupled with longitudinal river profile analysis. This analysis allows us to recognize that the topography of the French Massif Central is not fully equil...

摘要:Abstract(#br)To investigate denudation rates in the southern part of the Espinhaço Range (central-eastern Brazil) and to understand how this important resistant and residual relief has evolved in the past 1.38 My, cosmogenic 10 Be concentrations produced in situ were measur...

摘要:Abstract(#br)The 10 Be method was used to investigate the effect of mining activities on the natural denudation rates in alluvial sediments from catchments of the Southern Espinhaço Range (SER) in Minas Gerais State (Brazil). In this region, which is predominantly composed of ...
