Abstract The abstract describing the content of the publication or report |
The alluvium of the Oldbury Levels resembles similar Holocene alluvial sequences in adjacent areas. It consists of a sequence of alternating silty clay and organic deposits which represent deposition from estuarine waters and under periods of terrestrial peat growth during phases of marine regression against a background of gradually rising sea levels. Pollen evidence appears to reflect gradual change in the flora associated with changing tidal regimes, broader environmental change and the encroachment of human landuse which gradually diminished the forest cover. Foraminifera and very limited plant macroscopic remains supply evidence which support the conclusions drawn from the sedimentary evidence. Buried Roman archaeological sites, lying close to the dry-land margin, occur within estuarine alluvium which appears to have continued to be deposited, at least occasionally, while the sites were occupied. This suggests that the sites were sometimes flooded, and increasingly so towards the end of the occupation, perhaps indicating seasonal use of the floodplain edge. Darker bands of dispersed organic matter, known as stasis horizons, are considered to be depositional strata, and not in situ accumulations of A-horizon organic soil material. While some form surfaces from which cracks extend downwards, implying that they formed during periods of persistent drying, there is little associated mixing or other evidence for soil formation. Thus they probably represent only short periods of relative stasis within periods dominated by continuing alluvial silt deposition under tidal conditions. | ||
