Abstract

The Southern Uplands fault of Scotland has been traced into Ireland as far as Carrick-on-Shannon where it disappears beneath the Carboniferous. It has been suggested that it does not continue to the southwest. Evidence on the published Bouguer anomaly and vertical magnetic anomaly maps of central Ireland, however, suggests a continuation to Galway, necessitating a slight divergence toward the south rather than a straight-line extension to the southwest. It could be speculated that the continuation follows the north edge of Galway bay, but such a proposal has no geophysical support and involves other untenable considerations.
