The newly identified Ardglass–Ballycastle dyke swarm ( Fig. 3 ) comprises generally NNW–SSE-trending dykes that appear to intrude the Lower Basalt Formation...

...M. AFTALION; M. D. MAX Abstract Two sets of U-Pb zircon data from widely spaced specimen sets in the oldest migmatites in the Annagh Division gneisses yield upper intercept ages of 1297 +164 -101 and 1224 +192 -64 Ma and lower intercept ages of 869 +69 –118 and 813 +166 – 269 Ma.
