Moneen Quarry is a large working (in 2008) limestone quarry, operated by Roadstone Provinces Plc, on the outskirts of Castlebar, Co. Mayo in the west of Ireland (Irish grid ref. M 162908).
The rock type is Lower Carboniferous limestone and contains fossils of corals and shells, the latter commonly Nautiloids.
Small cavities occasionally occur in the fossil shells, and sometimes also without any apparent association with fossils. Cavities are scarce, often being confined to particular beds within the limestone, and even then, only parts of those beds, as can be seen in the quarry face. They are rarely more than 10 cm across but contain a variety of minerals, and when these do not completely infill the cavities they can afford small, well-crystallised specimens.
Situation in 2008: Due to health and safety concerns access to the quarry is only by prior appointment, and will include a safety induction video and a chaperon.
