The Buried Pre-Glacial Channel at Newcastle, Co. South Dublin
Abstract:AbstractThis paper describes a buried, presumed pre-glacial, channel feature at Newcastle, 20km south-west of Dublin, which was discovered by drilling and geophysics in 1981. It is considered to be fluvial in origin with a possible karstic component. The eastern 2km of the buried channel contains a suite of varied channel sediments which may be of Cenozoic age. These sediment infills have been partly weathered under warm and humid conditions and also contain possibly reworked base metal mineralisation. It is envisaged that the channel may have discharged to the west into the Palæogene Portarlington Channel which drained the Thulean Dome situated to the north-east.
