The use of paleomagnetic data to delineate the history of the development of the Connemara Antiform

The tectonic evolution of the Connemara Gabbro Suite as deduced from careful tilt correction of the initial remanence directions, and interpretation of locally reset magnetizations is substantially in agreement with that based on purely geologic criteria. Fold tests of remanence suggest the gabbro bodies acquired their remanence after the F3 folding phase but before the F4, Connemara Antiform folding phase, sometime between 440–490 Ma. After …
