Abstract: |
The cart-based gradiometer system used a Leica Captivate RTK GNSS instrument, which receives corrections from a network of reference stations operated by the Ordnance Survey (OS) and Leica Geosystems. Such instruments allow positions to be determined with a precision of 0.02 m in real-time and therefore exceeds European Archaeologiae Consilium recommendations (Schmidt et al. 2015).
The detailed gradiometer survey was conducted using four SenSys FGM650/3 magnetic gradiometers fixed horizontally 1 m apart on a non-magnetic cart with an effective sensitivity of 0.03 nT. The detailed gradiometer survey has been successful in detecting anomalies of possible archaeological and agricultural origin.
A possible ditched enclosure of unknown origin has been detected in the south of the site, within an area of ridge and furrow. A more natural origin, such as a natural drainage feature, cannot however be ruled out.
Various anomalies representative of the past agricultural use of the land have been detected. Ridge and furrow cultivation dating mainly from the medieval period has been identified across the site and are linked to the nearby settlements with a medieval origin including the villages of Belton and Tonge, as well as Grace Dieu Priory. Several former field boundaries have also been identified which correspond with field boundaries seen in the OS 1st edition (1883) mapping.
In addition to this natural variation in the underlying deposits, drains and various magnetic trends have been identified across the site. Areas of ferrous and magnetic disturbance have been detected and are associated with the edges and entrances to fields. |
