Description
A geophysical survey was undertaken of an area 100m by 100m in the NE corner of the field centred on TL 930 277, the approximate location of an excavation in 1984 of two Roman inhumation burials (MCC7078).<1>
Two techniques were used for the survey – magnetometry and electrical resistance measurement. The magnetometer survey was carried out over the period June to August 2013 using a Geoscan FM18 Fluxgate Gradiometer. An E–W base line was established near the NE corner of the field, and grids 20m square running NS and EW were set out. Each grid was surveyed in a S to N direction along lines 1m apart, taking 4 readings per metre along each line. The resistivity survey was carried out in April 2014 with a TR Systems resistance meter using the same E-W base line and grid layout. Each grid was
surveyed along lines 1m apart, taking 2 readings per metre along each line.
The survey located a number of linear features that suggest ditched enclosures (interpreted as Roman but could be later), together with the outline of a more substantial rectilinear or 'L' -shaped feature, and several unusually large pit like features.
