Sedimentary provenance of Silurian basins in western Ireland during Iapetus closure

Three Silurian basin fills, the Llandovery-Wenlock Croagh Patrick and Killary Harbour - Joyce Country successions and the Ludlow - Pridoli Louisburgh-Clare Island succession, overstep the tectonic contacts between elements of the Grampian (Taconic) accretionary history of the Caledonian – Appalachian orogeny in western Ireland. New U-Pb detrital zircon data from lower strata of these Silurian rocks provides insight into basin evolution and paleogeography.
