Short summary
We evaluate luminescence signal resetting in single-grain K-feldspar from modern fluvial analogues in Chile. Our results show a uniform sample-average bleaching trend but strong grain-scale variability. Residual doses are independent of feldspar geochemistry and catchment lithology but scale with natural dose. Taken together, these findings refine palaeodose correction strategies and support defining sample‑specific bleaching thresholds for luminescence‑based sediment tracing.
