A geophysical evaluation programme comprising topsoil magnetic susceptibility mapping and gradiometer survey was carried out on land immediately adjacent to the north and east of Brauncewell Limestone quarry in advance of proposed quarry extension. A triple ditch system (of probable prehistoric date) visible as a cropmark from the air crossed the exisiting quarry and part of the survey area to the north, whilst archaeological excavation in advance of the existing quarry had revealed further evidence for a multiple-phase complex of Roman activity and quarry pits continuing into the late 3rd century AD. The magnetic survey north of the quarry located the triple ditch system, whilst a number of other areas of anthropogenic modification of soils identified by magnetic susceptibility mapping, were demonstrated by magnetometry (gradiometer survey) to represent the location of underlying 'cut' features, representing ditches, enclosures and a possible structure. There was little magnetic evidence however that the complex of previously excavated archaeological features extended signficantly east of the extant quarry. [Au]

<summary>An evaluation comprising magnetic susceptibility and magnetometer surveys identified anomalies consistent with old field boundaries and possible archaeological features. Auger survey confirmed one anomaly to comprise a burnt clay surface, probably associated with salt production. {italon}AIP{italoff}{spacea}
