New data on Early Dinantian (Early Carboniferous) stratigraphy and sedimentation in South Cork, Ireland

Abstract

The sedimentology and stratigraphy of the Dinantian (Lower Carboniferous) Kinsale Formation are described from ten major coastal sections in south Cork, Republic of Ireland. Palynological correlations between the sections are outlined, and subdivision of the Kinsale Formation into three members is proposed. Members I and 3 are dominated by mudrocks, and are separated by the more sandy member 2. Sediments assigned to member 1 were deposited in a deep-water, marine environment below wave base, whereas members 2 and 3 were deposited on a shallow marine, muddy platform, where sandy shoals built up. The latter are especially well developed in member 2.
