Measuring tectonic and climate influence son catchment denudation rates

Editor’s Highlight—


This work presents a dataset from an arid landscape that quantifies topographic control on denudation rates. As such it provides an important end member for the growing understanding of how climate and tectonics shape the Earth’s surface. The extensive dataset consists of catchment-averaged denudation rates inferred from cosmogenic nuclide concentrations measured in modern river sediments collected along the western flank of the Andes in northern Chile. The authors investigate the potential controls of tectonic and climate on the spatial distribution of denudation rates and conduct a statistical factor analysis in which they consider the inferred denudation rates together with various morphometric parameters representative of the considered catchments. They conclude that local tectonic processes exert the main control on denudation rates along the in the region.
