Short Pape: Movements on the Southern Upland fault

Abstract
Consideration of the distinct sequences within the Northern Belt suggests that the Southern Upland fault (SUF) lies to the north of the ‘conventional’ line in E Scotland, SW Scotland and NE Ireland. Comparisons of clasts in mass flow conglomerates in the Southern Uplands with granites in western Newfoundland suggest large Ordovician and Silurian strike-slip movements, while southerly-derived clasts in Late Silurian Midland Valley conglomerates suggest post-Silurian movements. In western Ireland, the pre-Devonian movements on the SUF probably continued along the Skird Rocks Fault. Post-Silurian movements on the SUF may have extended along the Clew Bay fault zone or the Fergus shear zone.
