Abstract

Hitherto unreported tufa-depositing springs occur in Glenasmole, Co. Dublin. They owe their presence to limestone-rich fluvioglacial gravels and sands, which overlie impermeable grey boulder clay of Midlandian age, and give rise to a well-marked spring line. Preliminary chemical and scanning electron microscope analysis suggests that the calcium carbonate is precipitated around plant fibres (especially mosses) as euhedral, platy or rhombohedral calcite crystals. Whether this is by inorganic precipitation or whether biological processes are involved is not yet known.
