The Quarry Directory shows the location of sand and gravel, crushed rock and dimension stone quarries in Ireland.

A questionnaire was sent to all known active quarries and pits (around 1,700). A location map (Ordnance Survey Ireland (OSI) 1:50,000 Discovery Series) was provided to verify the location. Mines were not included. There are currently only two active metal mines in Ireland, the Navan and Lisheen zinc-lead mines.

Most questionnaires (for 22 counties) were sent out in the latter half of 2012 with the remainder being sent out in 2013. Some follow-up phone calls were made in late 2013 and mid-2014. Around 360 replies were received, for both active and inactive quarries and pits.

This map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.

It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).

The data is shown as points. Points are coloured according to rock type. Each point holds information on the quarry name, address, contact details, operational status, operator details, product, output, processing, ancillary activities, rock type and market.
