Abstract
The Arenig to Caradoc palaeogeographic evolution of the Harlech Dome region is interpreted from a study of the volcanic and sedimentary successions on the eastern and southern flanks of the Dome. Acid ignimbrite volcanism is shown to have been associated with periods of uplift and intermediate to basic volcanism with periods of subsidence. The evolution of the region can be compared to that of an island arc.Keywords
