Abstract: |
The two evaluation trenches showed natural sands and gravels overlain by peats and alluvial clays. The surface of the Pleistocene\Early Holocene deposits indicated a series of braided river channels within a low-lying area on the western margins of a main channel. A borehole survey showed this channel to be over 200m wide and c.3m deep. This feature would have formed a major part of the floodplain landscape from the Early Holocene and probably became a major drainage feature when the other Holocene channels to the west became abandoned. It is possible that the channel forms an abandoned arm of a former course of the Great Breach Dyke, which existed from the Early Holocene period into the Bronze Age. A Mesolithic land surface was identified with rising sea levels leading to widespread peat formation by the early Neolithic into the Bronze Age, Within the peat deposits were worked timbers which may have formed parts of a structure, possibly a trackway constructed to access or traverse the wetlands. The overlying alluvial silts and clays are likely to be of Iron Age, medieval and historic date representing an inundation of the floodplain. The upper 1.20m comprised dumps which represent making up and levelling of the site prior to the construction of the railway and associated buildings in the vicinity. The foundations of a chimney of the adjacent Listed power station were also recorded. |
