Summary

A geomagnetic survey indicates that the Carboniferous igneous rocks in the Tickenham area are more extensive than previously recognized. Inversions of the magnetic anomalies suggest the causative basaltic body is tabular in form, conforms to the regional dip and has a coplanar magnetization. The magnetization vector orientation indicates emplacement during a period of magnetic field reversal and thus at a time different from other Carboniferous igneous rocks in the region.
