Understanding Earth’s eroding surface with 10Be

[摘要] For more than a century, geologists have sought to measure the distributionof erosion rates on Earth’s dynamic surface. Since the mid-1980s, measurements ofin situ 10Be, a cosmogenic radionuclide, have been used to estimate outcropand basin-scale erosion rates at 87 sites around the world. Here, we compile, normalize,and compare published 10Be erosion rate data (n = 1599) in order to understand how, on a globalscale, geologic erosion rates integrated over 103 to 106 yearsvary between climate zones, tectonic settings, and different rock types.
