Uranium comminution age responds to erosion rate semi-quantitatively

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