Abstract

Fine grained magnetite was introduced onto a semi-arid grassland hillslope in 1992, as part of a set of rainfall-simulation experiments. Using measurements of magnetic susceptibility, the median distance travelled by these magnetite grains during subsequent natural runoff events in the 16-year period up to 2008 was estimated. Coupling this estimate to direct measurements of sediment flux obtained during the rainfall-simulation experiments has enabled estimation of the erosion rate over this period. The result is an order of magnitude less than obtained from a study based on Cs 137 in a nearby catchment, and compatible with the longetivity of continents
