Reconstructing past variations in erosion and sediment transport using uranium-series isotopes

Understanding how erosional and sediment transport processes have responded to past environmental changes has become increasingly important with the increased risk of future climate change. Recently-developed geochronological tools have enabled the response of hillslope-fluvial systems to such changes to be studied. This thesis focuses on the developing comminution dating (or the comminution age) technique that utilises uranium (U) isotopes to constrain the time elapsed since detrital minerals were reduced to ca. systems, the comminution age represents the sediment residence time, and applied to sedimentary deposits of known depositional age, the palaeo sediment residence time can be constrained.
