Summary:This rare Upper Devonian volcanic episode in SW Ireland formed three separate volcanic centres which erupted a rhyolitic suite of thick flows and tuffs. The largest of the centres possessed a system of contemporaneous faults, producing a subcircular depressed area enclosed within a graben 1.5 km across. These faults led to rapid thickness variations in many volcanic units; a pooled lava flow reached a thickness of 300 m. The site of a major elongate vent lies along one such fault; rapid erosion of its poorly lithified walls generated coarse sandstone boulder agglomerates and was related to the absence of normal air-fall tuffs unmixed with terrigenous sand.
