Abbeytown Mine and Quarry, Ballysadare, Co. Sligo

摘要

The historic Abbeytown lead-zinc-silver deposit, now the site of a limestone quarry, has produced some of Ireland's best calcite specimens. Fine specimens of other minerals have also been found including large 'Herkimer Diamond' quartz crystals, sometimes with visible fluid inclusions. Most of the minerals were found in the 1990s when quarrying exposed vugs surrounding the base metal mineralisation and a possibly unrelated calcite pipe. Recently enargite, as euhedral crystals, has been found in a small area of vuggy limestone near the entrance to the quarry.
