Rare basaltic and doleritic dykes, of uncertain age and affinity, occur within the Highland Border Complex and the Lower Devonian rocks to the south of the Highland Boundary Fault. Within the Highland Border Complex they typically trend approximately north-easterly, parallel to the strike of the Highland Boundary Fault. Within Lower Devonian rocks the dykes have north-easterly to more easterly trends.
