The stratigraphy, sedimentology and palaeontology of the Pleistocene Knocknasilloge Member, Co. Wexford. Ireland

| Summary: | Abstract The Pleistocene Knocknasilloge Member, an upward coarsening sequence of massive and laminated muds to cross‐laminated fine sands and silts, was deposited in a series of shallow lacustrine basins formed at the retreating margin of the Late Devensian Irish Sea ice‐sheet. Sedimentary successions mark increased proximity to a sediment input source and a shift from lake floor suspension sedimentation to bottom traction in low‐angled prodelta foresets and distributary barmouth channels. The microfauna contained within the sequence is derived from preexisting climatic stages and there is no evidence to support either an in situ interglacial or glaciomarine origin, as previously proposed. |
