Abstract: |
A temporary grid system will be established over the site and marked out using canes. The location of the grid will be set out using an RTK GPS system theoretically accurate to some 0.01m and referenced to OS co-ordinates. Hand Held: Data will be collected using a Bartington Grad 601-2. The instrument consists of two paired sensors (see below) and readings are logged at 0.25m centres along traverses 1.0m apart across 30m grids. The collection of data at 0.25m centres provides an appropriate methodology balancing cost and time with resolution as per Historic England guidelines. Two sensors mounted 1m horizontally apart and very accurately aligned to nullify the effects of the earth's magnetic field. Readings relate to the difference in localised magnetic anomalies compared with the general magnetic background. The survey at Bretch Hill, Banbury, has identified a complex of features of archaeological interest in Area 1. These comprise three probable round houses and associated structures, likely to include workshops, sheds and barns plus yards and small paddocks. These can be inferred because of the strongly enhanced magnetic deposits present on the site; the accumulation of rubbish and waste products, plus burnt material, will result in such enhancements. Similar results have been found on Iron Age / Romano-British small settlements / farmsteads. Elsewhere, ridge and furrow cultivation is visible in all the fields except for Area 2 which has modern magnetic disturbance. Two service pipes have also been mapped in the survey. |
