Measuring middle Pleistocene erosion rates with cosmic-ray-produced nuclides in buried alluvial sediment, Fisher Valley, southeastern Utah

Quantifying rates and timescales of geomorphic processes : part 1. Special issue

Description :
The AA. describe how measurements of the cosmic-ray-produced radionuclides Be 10 and Al 26 in alluvial sediment can be used to develop a continuous record of erosion rate changes through time. The AA. illustrate the method, and evaluate its uncertainty and thus usefulness in realistic situations, with an example from a middle Pleistocene alluvial section in Fisher Valley, Utah. Finally, they suggest how it might best be employed in future to answer questions about the relationship of climate, tectonics, and landscape evolution.
