Tectonically active regions produce disproportionately high sediment (physical erosion) (Milliman & Syvitski, 1992) and dissolved (chemical weathering) (Gaillardet et al., 1999) fluxes to the oceans, and therefore play an important role in the global carbon cycle. As an active mountain belt, the Taiwan orogen alone bears eight of the world's 13 rivers with sediment yield >10 4 t/km 2 /yr (Milliman & Farnsworth, 2011) that results from active tectonics and frequent typhoon events. Rates of mineral weathering from silicates and sulfides (Blattmann et al., 2019;Bufe et al., 2021) and rates of organic carbon transport and oxidation (Hemingway et al., 2018;Hilton et al., 2012) in the Taiwan orogen are among the highest worldwide as these processes are driven by rapid denudation. Hence, knowledge of denudation rates that integrate over time scales
