Abstract: |
This report was commissioned by AC Archaeology Ltd on behalf of clients and was produced by Substrata in preparation for submission of a forthcoming planning application for a single wind turbine with access route. The magnetic contrast across the survey area was relatively good and was sufficient to distinguish between anomalies representing potential archaeology and natural deposits. Thirty-five magnetic anomaly groups were identified as representing potential archaeological deposits. Twenty-eight of these groups may represent large filled pits or similar deposits and stand out clearly in the data set. With this type of anomaly it is difficult to distinguish archaeological deposits from natural deposits unless there is some clear distribution. Their distribution does imply that they may be associated with mining or quarrying but other past activities cannot be ruled out. Only further archaeological investigations will clarify whether the anomalies represent archaeological features, natural features or a combination of both. The remaining anomalies characterised as potential archaeology represent one spread of possible archaeological material, five linear deposits and one curvilinear deposit. Of the five linears, two are clearly former Cornish bank field boundaries and one of these was recorded on Ordnance Survey maps between 1882 and 1978. The other linear groups and curvilinear groups cannot be characterised further archaeologically except to say that such groups often represent features such as ditches or banks. |
