Abstract: |
A single trench archaeological evaluation was carried out by Museum of London Archaeology (MOLA) on the site of The Lee Tunnel access shaft at Thames Water Beckton Sewage Treatment Works (STW), Beckton London, IG11. An adjacent geoarchaeological borehole recorded the presence of late Pleistocene gravels at c-2.2m OD (4.5m below present ground level). The surface of (fluvial) sandy clay/clay sand channel deposits of potential late Pleistocene/early Holocene date formed the trench base, at c -0.9m OD. Root bowls and tree bases (probably alder) were recorded truncating the layer along the east face of the trench. A shallow channel, running approximately 2m north-south at the north end of the trench shows a brief episode of fluvial erosion or scour. Deposits of peat were recorded in the trench section and were present throughout the trench extent to a surface height of -0.2m OD. The characteristics of the peat in the evaluation trench reflect its location within, or adjacent to, ancient river channels. Alluvial clays and silts accumulated above the organic deposits, probably during the Iron Age and historic periods which might represent seasonally flooded meadowland or estuarine environments. A compressed layer of topsoil and turf representing historic open grassland survived at the top of the alluvial profile at 1.2m OD. Modern made ground, 1.3m thick sealed the alluvial sequence. The trench showed no evidence of prehistoric human activity or environmental interaction. However, the deposits examined have good potential for reconstructing the prehistoric environment |
