Abstract: |
Wessex Archaeology was commissioned by Jackson Civil Engineering Ltd (‘the client’) on behalf of the Environment Agency to undertake a programme of geoarchaeological and archaeological monitoring of additional Ground Investigation (GI) works and deposit modelling in advance of development proposals for a flood alleviation scheme at Lowdham, Nottinghamshire. Recent Ground Investigations (GI) (Arcadis 2020, WA 2020) carried out in the south of the Site recorded superficial alluvial and colluvial sediments over solid bedrock mudstones and sandstones. Generally, the superficial deposits are capped by topsoil; however, made ground was recorded in 15 deposit records and ranged in thickness from 0.25m in TP206 to 2.3m in TP207.
The deposit models place the sediments at the Site in their wider topographic context. The sands and gravels were depoSited within a braided river system of the Cocker Beck in a periglacial environment during the late Devensian 15,000 to 10,000 years before present. While active, the river system would have been characterised by longitudinal gravel bars and intervening shallow water channels.
Deposit modelling showed the upper surface of the sands as sloping down from the west to the east and ranged in thickness from 0.3m thick in TP05 at 33.49m OD to 2.6m in BH05 at 32.83m OD. The sands and gravels were overlain by minerogenic deposits of fine-grained alluvium comprising silts, sands and clays. These alluvial deposits were recorded across the Site, present in thicknesses from 0.1m in TP202 at 31.7m OD to 2.0m in BH102 at 31.4m OD.
The age of the sands is currently unknown, but they are likely to be terminal Pleistocene and/or Holocene in date. At Farndon Fields, 14km north-east from the Site, comparable sandy sediments originally considered to be Holocene alluvium were shown to reflect much more complex, polygenetic deposition, including two phases of alluvial sedimentation, one which may date to late Pleistocene to early Holocene (c. 8–13 Ka) and one to later Holocene (c. 3–1 Ka) (Wessex and Cotswold Archaeology 2017). |
