    Abstract

    Excavations of surface deposits at Tullyallen Quarry 1.5km north-west of Drogheda revealed a formation of glaciomarine deposits at 29.4 to 40.0m O.D. between two till formations. The glaciomarine deposits contain a cold water fauna of mollusca, crustacea, ostracoda, foraminifera, hydrozoa, and also sparse remains of land plants and marine algae. The upper till formation was deposited by ice from the Irish Sea Basin which moved in a south-westerly direction across the site. The lower till formation was deposited by ice from the Irish midlands, which moved eastwards and south-eastwards towards the Irish Sea Basin. These deposits overlie a variety of residual deposits that are sealed in solution pipes and fissures within the karstic surface of the Lower Carboniferous limestones. The glaciomarine and glacial deposits are considered to belong to the Munsterian Cold Stage of the Pleistocene Period; the residual deposits being older.
