Summary Palaeomagnetic measurements on rhyolites from Northern Ireland showed that there were two components of magnetization present. A normal component with magnetic characteristics appropriate to a viscous magnetization disappeared at temperatures of about 170–220° C. The remaining magnetization at higher temperatures was opposed to the direction of the Earth's present magnetic field, and was interpreted as a stable magnetization originally acquired by the rhyolite in a reversed magnetic field.
