The aims of this study were to provide a sedimentological analysis and environmental interpretation for the Mullaghmore Sandstone Formation and its equivalents, extending from south Donegal to south Sligo and into the north of Ireland. Following this, correlation of the sandstone sequences on a local and subsequently a regional scale was attempted with a view to identifying any patterns that may exist and their causes. On examination of the biostratigraphical data for the Mullaghmore Sandstone as a whole, it was hoped to determine whether or not an overall age date could be established for the formation. The Mullaghmore Sandstone is a clastic interlude in a dominantly carbonate-shale succession, implying that it’s top and basal contacts may represent significant sea level changes. These boundaries were examined and correlated between localities. The Mullaghmore Sandstone Formation forms part of the Mississippian succession of north and north-west Ireland. Biostratigraphical evidence indicates that the Mullaghmore Sandstone Formation is predominantly Arundian. In this study it has been examined in detail at the coastal sections of Mullaghmore, Carrowmoran, Kildoney and Inishmurray Island and in the quarries of Mountcharles. A reconnaissance study has also been carried out to examine the eastern extent of the Mullaghmore Sandstone into Northern Ireland.
