Description: “Aggregates” is the term geologists use to describe rocks used for building and construction purposes. Aggregate Potential Mapping aims to identify areas where aggregate is most likely to be found.This map shows the crushed rock aggregate potential across Ireland. To produce this map, scores from 1 to 10 were given to each area based on several factors: Rock Type Suitability (2.8) - This tells us if the rock in an area is suitable for building purposes.Deleterious Substances (0.7) – This tells us if there is anything within the rock that might make it unsuitable for building purposes.Number of quarries (1.2) – This tells us if this rock is already being used for building purposes.Area (0.5) – This tells us if there is enough rock available to be worthwhile opening a quarry.Overburden thickness (2.0) – This tells us how much soil and other material needs to be removed to get to the rock.Elevation (0.8) – This tells us the height above sea level.Markets (1.2) – This tells us how close the area is to places where there will be a high demand for building materials.The final score was a number between 5 and 100.This map shows the scores sorted into five different ranges:Very High potential - redHigh potential - orangeModerate Potential - yellowLow Potential - greenVery Low Potential - blueThis map is to the scale 1:100,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 1km.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas). The data is shown as polygons. Each polygon holds information on the potential range value, the county it is located in and the area in m2.Please read the metadata lineage for further information.
