Uranium comminution age responds to erosion rate semi-quantitatively

摘要：

　　Here we present(234U/238U)data from river sediments on the Tibetan Plateau.The(234U/238U)ratios of a specific grain size fraction show a good correlation with erosion rates,which were determined by in situ-produced cosmogenic nuclides.This correlation has also been observed in a wide range of geomorphic settings,which suggests that the(234U/238U)ratios of fluvial sediments have great potential to record the erosion rate.
