A magnetic survey was carried out along a NW–SE trending monchiquiteintrusion near Llanllowell, Gwent. The intrusion was previously thought to be a dyke, 23m long and 5 m wide, and that it may have been an extension of a second monchiquite intrusion at Great House to the southeast. However, the survey revealed the intrusion to beat least 34 m long, up to 20 m wide, and independent of the Great House intrusion. Evidence suggests that both of these monchiquite intrusions in central Gwent may have been feeder pipes to post-Lower Carboniferous volcanoes.
