Abstract: |
The CAU watching brief in July 2019 covered sampling of loess to research the environment of the last glacial. Chynalls Point is the site of a Scheduled promontory fort (List Entry no. 1003103) and Watching brief was required by Historic England, as set out in a WSI and agreed through SMC. The works consisted of Proxy, Luminescence, Anisotropic Magnetic Susceptibility, and Single Grain Provenance sampling. This resulted in a cut measuring c0.45m north-south along the cliff exposure, up to 0.7m maximum east-west into the cliff, and 1.25m from ground surface to bottom. The site lies in a former coastal field appearing on the OS map of c1880. Topsoil here is very thin and the field here may have been used as rough pasture rather than cultivated. Initial indications were that the material sampled would be interpreted geologically as primary loess (with darker colouration at around 0.5m from the surface possibly because of higher water content) and possibly loess-derived colluvium below c0.8m from the ground surface. A flint was observed in situ in the cliff 22.8m to the north 0.2m from the ground surface. This appears to be a primary waste flake on a locally derived pebble, undated, but prehistoric. There is potential for recording the section with the flint and relating this to the sampled section and so to the dating and environmental results produced by the sampling in due course. This potential is vulnerable to loss as the site is subject to continuing coastal erosion. |
