Abstract: |
Wessex Archaeology (WA) was commissioned by Mott MacDonald Bentley Ltd to undertake geoarchaeological and archaeological monitoring, along with deposit modelling, of Ground Investigation (GI) works on a c. 0.5-hectare parcel of land at Ufton Nervet, located in the Kennet Valley, Berkshire. The GI works comprised three cable percussion boreholes to 15 m, six cone penetrometer tests (CPT) and six DCP/TRL followed by hand dug test pits. No archaeological remains or features were encountered during geoarchaeological monitoring. The Pleistocene sands and gravels across the Site are likely to be associated with the Beenham Grange Member, representing the final phase of Pleistocene fluvial deposition during the Late Devensian (MIS 2, ca. 16,000–11,500 cal BP) Lithologically variable deposits of fine-grained alluvium were encountered in all GI locations across the Site and were recorded between 0.18 mbgl and 1.70 mbgl. These alluvial deposits are considered to be Holocene in date, accumulating on the floodplain of the River Kennet. These deposits include those infilling topographic lows in the Pleistocene gravels, including possible relict channels incised in the Late Pleistocene/Early Holocene, in addition to broader deposits of alluvium accumulating across the wider floodplain. Organic-rich units occur in nine hand dug test pits, as either interbedding or underlying minerogenic alluvium. Such organic deposits have the potential to preserve palaeoenvironmental remains suitable for environmental analysis or scientific dating. Waterlogged archaeology may also be preserved and thus the organic-rich deposits are considered high geoarchaeological potential. The overlying topsoil, as well as the underlying reworked clay bedrock and London Clay Formation have negligible geoarchaeological potential. The scope for any further archaeological evaluation and mitigation works will need to be considered when the specific design solution has been finalised, as this will have a direct impact on the requirement for and extent of any archaeological evaluation and mitigation works |
