A Combined Cosmogenic Nuclides Approach for Determining the Temperature‐Dependence of Erosion

Physical weathering in cold, steep bedrock hillslopes occurs at rates that are thought to depend on temperature, but our ability quantify the temperature-dependence of erosion remains limited when integrating over geomorphic timescales. Here, we present results from a 1D numerical model in-situ cosmogenic 10Be, 14C, and 3He concentrations evolve as function rate, style, ground surface temperature. We used explore suitability these nuclides for quantifying areas undergoing non-steady state erosion, well relationship between erosional stochasticity. Our suggest even stochastically eroding settings, 10Be-derived amalgamated samples can be estimate long-term rates, infrequent large events lead bias. The ratio 14C 10Be evaluate stochasticity, determine offset an apparent rate rate. Finally, concentration relative paleothermometric interpretations derived it, unaffected by These findings, discussed context mountainous regions, indicate 10Be-14C-3He system quartz offers method temperature-sensitivity high-alpine environments.
