Vegetation influences erosion by stabilizing hillslopes and accelerating weathering, thereby providing a link between the biosphere Earth's surface. Previous studies investigating vegetation effects on have proved challenging owing to poorly understood interactions other factors, such as precipitation surface processes. We address these complexities along 3500 kilometers of extreme climate gradient Andean Western Cordillera (6°S 36°S latitude) using 86 cosmogenic radionuclide-derived,...

River‐borne quartz carries a cosmogenic nuclide memory that is function of the catchment‐wide erosion rate. This record may be preserved in fluvial deposits such as river terraces. If age terrace independently known and transport time system relatively short, then upstream rate at deposition can determined. We have used nuclides to date terraces lower Meuse catchment, Netherlands, obtain 1.3 Ma paleoerosion rates 104‐km2 drainage basin comprising Ardennes Mountains. Paleoerosion were uniform...
Abstract. Weathering of bedrock to produce regolith is essential for sustaining life on Earth and global biogeochemical cycles. The rate this process influenced not only by tectonics, but also climate biota. We present new data soil production, chemical weathering, physical erosion rates from the large ecological gradient Chilean Coastal Cordillera (26 38∘ S). Four study areas are investigated span (from north south) arid (Pan de Azúcar), semi-arid (Santa Gracia), Mediterranean (La Campana),...
Abstract The concentration of cosmogenic nuclides in rocks exposed at the Earth's surface is proportional to total duration their exposure. This basis for bedrock exposure dating and has been used constrain valley lowering rates Taroko gorge, eastern Central Range, Taiwan. gorge contains a uniquely complete geomorphic record fluvial lowering: continuous, fluvially sculpted surfaces are present lower 200 m this marble gorge. Assuming no post‐fluvial erosion wall, situ ‐produced 36 Cl measured...
We evaluate spatial and temporal variations in denudation of the north-central Wasatch Mountains, Utah, by determining catchment-wide rates with 10Be concentrations alluvial sediment comparing these previously published data on rock uplift exhumation range. Catchments draining range front show relatively little variation rate (0.07–0.17 mm/yr), while steeper (mean hillslope gradient >30°) catchments core larger (0.17–0.79 mm/yr). attribute to landsliding hillslopes at threshold gradients;...
Glacial boulders and soils on moraines are often dated to quantify the timing of glaciations and/or rates chemical weathering in moraine chronosequences. A common assumption is that crest erosion soil mixing unimportant. However, several studies suggest denudation may be substantial.
