ALCESTER GATEWAY STORE SITE. SOIL REPORT.
Author(s): Matt Canti
At the Gateway stores site, Alcester, a natural sequenceof fluviatile deposits has been compared with the const-ructionial material of a Roman clay rampart and various other layers of the excavation. The natural deposits appear to consist of a coarsening-upward suite of marsh clays overlying Devensian gravels. Particle size analysis has shown that only one of the samples tested (a material shown to be derived from therampart) can be precisely related to the natural clays. The remainder, including the rampart samples, have too high a silt/clay ratio to be derivatives of the sequencethat was analysed. Because of the broad similarity between all the samples, it is suggested that natural deposits with a higher silt content would be found locally, reflecting small changes in channel sediment- ation.
