Abstract: |
The aim of the geoarchaeological investigations at the Ebury Centre site was to (1) clarify the nature of the sub-surface stratigraphy, in particular the presence and thickness of Alluvium and Peat across the site, and (2) to evaluate the potential of the sedimentary sequences for reconstructing the environmental history of the site and its environs. A programme of deposit modelling of the surface elevation and thickness of the major stratigraphic units at the site was carried out, incorporating geotechnical borehole descriptions and records from those boreholes monitored in the field. The results of the deposit modelling demonstrated a sequence of Late Devensian Shepperton Gravel, overlain by Holocene Alluvium, in places containing Peat (the Staines Alluvial Deposits), and Made Ground. The Gravel surface in the area of the site lies at between -1.0 and -1.8m OD, recorded at its lowest in the central and south-western areas of the site. The deposit model gives the impression of a linear depression, aligned approximately north-south, which may be related to a former channel in this area. The Gravel was overlain by variable thicknesses of sandy Lower Alluvium in the majority of boreholes, to a level of between -0.8 and 0.5m OD; this was overlain by the clay-rich Upper Alluvium, to a level of between 0.2 and 2.5m. Peat was recorded within the Upper Alluvium in two boreholes towards the north, at elevations between 0.7 and 0.9m OD (BH3) and 0.6 and 0.7m OD (DS1). The Peat is indicative of a transition to semi-terrestrial conditions supporting the growth of wetland vegetation. The Peat is confined to the northern area of the site, suggesting that it formed only in localised floodplain hollows, or has subsequently been eroded elsewhere by fluvial activity. However, in the absence of widespread Peat horizons at the site and the relatively thin (<0.2m) nature of the Peat, no further environmental archaeological investigations were recommended. |
