Schematic representation of the pathways of two different sediment grains from source to the location of sampling. The two grains originate from different locations possibly characterised by very different elevations and erosion rates, and can spend different amounts of time at different elevations (and depths within the transport layer) while transported through the drainage systems. Thus, the final cosmogenic nuclide concentration of the two grains reflects their potentially unique (and different) histories of erosion, transport, and deposition. Similarly the frequency distribution of cosmogenic nuclide concentrations in a large number of grains leaving the drainage basin should reflect the geomorphological character and history of the basin.
