Late Devonian and Early Carboniferous palaeogeography of southern Ireland and southwest Britain.

During the Strunian and early Carboniferous, a marine transgression brought marine conditions progressively northward over the former Old Red Sandstone Continent in Britain and Ireland. The progress of the transgression is found to have been episodic, but the causes underlying the northward shift of the shore line are difficult to assess. Subsidence in the S of Ireland and in SW England was very rapid, but there is a suggestion that some of the transgressive pulses, particularly those in the late Strunian, at the base of the Carboniferous and within the Middle Tournaisian, may have been caused by eustatic movements of sea level. -Authors
