Chemical analyses of fine-grained post-glacial alluvium in the middle Tyne valley, northern England, has revealed marked contrasts in the geochemical characteristics of late Holocene floodplain and channel sediments. Using multivariate statistical techniques, contemporary channel sediments, tills and pre-mining age alluvium from sites throughout the Tyne basin are compared and the results show that geochemical variability is diagnostic of sediment provenance from geologically distinct sub-catchments of the basin. Enhanced heavy metal content, notably Pb and Zn, provides a reliable means of identifying sediment derived from mineralised parts of the South Tyne basin, particularly during large-scale mining activity in the Northern Pennine Orefield between the mid-seventeenth and mid-twentieth centuries. However, lesser yet systematic differences in Pb content within pre-mining age alluvium also indicate a link between its deposition and soil erosion, deforestation and the development and expansion of sedentary agriculture during late prehistoric times.
