Abstract
Digitally processed aeromagnetic imagery has revealed an extensive
swarm of reversely magnetized Tertiary dykes in County Fermanagh,
Northern Ireland, 50 km west of the main outcrop of the Tertiary Antrim
Lava Group. The swarm covers an area >2000 km 2, and ground
magnetometer profiles across one example near Enniskillen show a
negative anomaly of c. 2000 nT. Synergistic display of the available
gravity and aeromagnetic data for the area shows a close coincidence
between the Dromore gravity high and this dyke swarm and suggests the
presence of a basic intrusive body at depth as the source of the magma for
the dykes.
