Abstract

This paper demonstrates a robust methodology for the C 14 dating of geomorphological sequences using a case study from the lower Ribble valley, northwest England. The approach adopted incorporates using greater number of ages, targeting plant macrofossils, obtaining replicate measurements from single horizons to assess the extent of reworking and the use of Bayesian approaches to test models of the relative order of events. The extent of reworking of organic materials and space-time dynamics of fluvial change means that it is critical that chronological control is sufficiently resourced with C 14 measurements. This approach has potential value in constraining the sequence of geomorphological development at scales that vary from individual sites to a catchment or region, furthering understanding of forcing and change in geomorphological systems
