Bedrock outcrop polygons have been derived from digitising outcrop locations from scanned 19th Century GSI field maps. The data was derived from mapping at a scale of 1:10,560 (6 inches to one mile). Individual map sheets were geo-referenced to an index polygon and checked...

The IMAGIN study has concluded that a number of areas with potential to support marine aggregate extraction exist within the Irish Sea and that marine aggregates can contribute to the sustainable management of demand and future use of aggregates in Ireland.

Data on the offshore geologic intrusive bodies around Ireland. An intrusion is liquid rock that forms under Earth's surface. Magma from under the surface is slowly pushed up from deep within the earth into any cracks or spaces it can find, sometimes pushing existing country...
-
This dataset contains a complete coverage for all mapped and digitised striae features for the island of Ireland. The Subglacial Striae is part of the Subglacial Landform group. The map forms part of the GSI Quaternary Map series. Data recorded on the maps includes the...

Water tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of...
-
This Hydrostratigraphic Rock Unit Groups map is a reclassification of the 1:100,000 bedrock geology map, created by grouping bedrock formations and members into 27 Rock Unit Group categories based on their hydrogeological properties and other factors.
