Abstract

The concentration of cosmogenic nuclides in rocks exposed at the Earth's surface is proportional to the total duration of their exposure. This is the basis for bedrock surface exposure dating and has been used to constrain valley lowering rates in the Taroko gorge, eastern Central Range, Taiwan. Without considering gorge wall retreat, the estimates therefore represent maximum incision rates. The long-term gorge development governed by tectonic uplift is superimposed by short-term variations in incision rates caused by climatic or regional tectonic changes
