Pits at the Plas Gogerddan site contained virtually no traces of bone due to the free-draining, slightly acid, fluvio-glacial substrate. Some pits could be identified as graves from the presence of coffin stains, but where there was no visible evidence, phosphate analysis was undertaken. Unfortunately, the fluvio-glacial sands and gravels have a limited phosphate-retention capacity, but also exhibit very marked local variability in texture. The best results were obtained by analysing the clay+silt fraction of samples, rather than the conventional fine earth and strong signs of phosphate enrichment were recorded in the central part of the feature.
