Service 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 granular aggregate potential across Ireland. To produce this map, scores from 1 to 10 were given to each area based on several factors:

Genesis-Petrology (2)

Number of pits (1.2)

Area (2)*

Thickness (2)*

Elevation (0.5)

Markets (1.2)

*In the case of ‘alluvium’ the factor is 1.0.

The factors were weighted by a multiplication factor (in brackets after the listed factors above). The final score is obtained by summing the weighted scores to give a final score ranging from 3.5 to 100.

This map shows the scores sorted into five different ranges:

Very High potential - red

High potential - orange

Moderate Potential - yellow

Low Potential - green

Very Low Potential – blue

Unlike the crushed rock potential map there are large areas uncoloured because sand or gravel has not been mapped in these areas.

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 polygons. Each polygon holds information on the Granular Aggregate Potential, the county it is located in and the area in m2.

Please read the metadata lineage for further information.
