A geophysical magnetometer survey was undertaken on land bordering Alfreton Road (the A38), Sutton-in-Ashfield, Nottinghamshire where it is proposed to submit a planning application for light industrial, general industrial and warehouse units, with associated infrastructure. The survey has identified anomalies consistent with modern activity and agricultural usage, particularly across the northern part of the proposed development area. The most numerous anomalies recorded by the survey are due to ridge and furrow cultivation, land drainage and boundary removal. Variations in the underlying Coal Measures bedrock geology are also recorded. A few ditch-like anomalies, possibly forming part of a system of pre-medieval field boundaries (also partly recorded by a survey undertaken in 2015 in advance of a previous development), have been recorded in the south-western quarter of the PDA. Several discrete anomalies have also been recorded which may be associated with the possible field system although this interpretation is tentative. No anomalies of definite archaeological origin have been recorded by the survey. The archaeological potential of the PDA is therefore assessed as low except to the south-west where it is assessed as moderate in and around the possible pre-medieval field system.
