Bedrock Geology 1:500,000 Ireland (ROI/NI) ITM

The 1:500k bedrock maps provide a simplified, smaller scale view of the bedrock geology of Ireland. The map was created in 2013 using the detailed 1:100k geology linework and polygons, which was adjusted and scaled to provide the best representation of the geology at this overview level.

The data represents a seamless bedrock geological dataset encompassing Rep of Ireland and parts of Northern Ireland at the 500,000 scale. This dataset is part of the ‘Bedrock Geology 500K Series’ (seamless bedrock geological dataset encompassing Rep of Ireland and parts of Northern Ireland) that comprises 3 parts – Bedrock Lithology 500K, Bedrock Faults 500K and Bedrock Dykes 500K.
