Abstract At time-scales of 102 to 105 years, erosion by rivers, landslides and glaciers can exceed 5 mm/y. Sustained denudation at these rates is sufficient to account for many of the rapid rates of unloading or cooling that are revealed by geobarometric or thermochronologic studies. Because feedbacks exist among many surface processes, determinations of erosion rates on a few geomorphic processes can be adequate to estimate mean rates across an entire landscape. Rates of fluvial and glacial… 
USING THERMOCHRONOLOGY TO UNDERSTAND OROGENIC EROSION
Erosion of orogenic mountain ranges exhumes deeply buried rocks and controls weathering, climate, and sediment production and transport at a variety of scales. Erosion also affects the topographic

[1] Quantification of denudation in the Transverse Ranges of California permits reconstruction of spatial and temporal variations in erosion that represent both the response and evolution of
An Evaluation of Erosional‐Geodynamic Thresholds for Rapid Orogenic Denudation
Tectonic and surface processes (e.g., erosion) act in concert to denude and flatten elevated topography during and following collisional uplift. In orogens that collapsed rapidly (<10 Myr), the
Timescale dependence of glacial erosion rates: A case study of Marinelli Glacier, Cordillera Darwin, southern Patagonia
[1] Erosion rates have been estimated for a number of glaciated basins around the world, mostly based on modern observations (last few decades) of sediment fluxes to fjords. We use time-constrained
Erosion and exhumation in accretionary orogens: Experimental and geological approaches
This study examines the role of erosion on exhumation and deformation history of accretionary orogens through experimental and geological methods. Fault propagation, kinematics, and exhumation rates
How and to what extent does the emergence of orogens above sea level influence their tectonic development?
Geodynamic modelling indicates that the emergence of initially submarine convergent orogens above sea level can have a significant influence on their subsequent tectonic development. This is because
Interpreting erosion rates from cosmogenic radionuclide concentrations measured in rapidly eroding terrain
A combination of numerical analysis and 10Be concentrations measured in sediment samples from the high‐relief Torrente catchment, southern Spain, allows us to investigate the sampling requirements
Dominance of tectonics over climate in Himalayan denudation
Landscape denudation in actively deforming mountain ranges is controlled by a combination of rock uplift and surface runoff induced by precipitation. Whereas the relative contribution of these
