Report and Survey Data from a Magnetometer Survey at Nadder Lane, South Molton, Devon, July 2022

This collection comprises a report, survey and interpreted data from a geophysical survey undertaken by SUMO Geosurveys on land north of Nadder Lane, South Molton, Devon in July 2022. The magnetometer survey has not recorded any magnetic responses that could be interpreted as being of definite archaeological interest. Numerous dich-like anomalies, linear trends and bands of increased magnetic response have been detected in the survey and assigned to the category of uncertain. They are likely to be due to a combination of natural and agricultural processes; however, archaeological origins for some of the responses cannot be entirely dismissed. One corroborated former field boundary has been recorded in Area 5 and a number of conjectural former field boundaries have also been plotted. Ridge and furrow ploughing is visible in the magnetic data along with a service pipe. A zone of magnetic disturbance is likely to be due to spreads of debris / made ground associated with modern agricultural processes.

本数据集涵盖SUMO Geosurveys于2022年7月在英国德文郡南莫尔顿纳德勒巷北侧陆地开展的地球物理勘探的报告、勘测数据与解译成果。本次磁法勘探未观测到可明确判定为具有考古价值的磁响应异常。勘测过程中发现了多处类碟状异常、线性构造带以及磁响应增强条带，均被归类为“存疑”类别。这些异常大概率由自然作用与农业活动共同引发，但仍无法完全排除部分异常的考古成因。5号区域内已记录一处经证实的古田界，同时还绘制了多处推测性古田界。磁法数据中可见垄沟耕作痕迹与一条服务管线。一处磁扰动带大概率由现代农业活动产生的堆积物/人工填土所致。
