Bedrock Boreholes (provisional)

We are currently working on upgrading our borehole and core store databases.  In the meantime, this database may provide useful information.  If you have remaining queries, contact brian.mcconnell@gsi.ie.  For core store queries and to request access, please see core store page.

Bedrock 3D Model of Dublin

The Bedrock 3D model of Dublin is an interpretation of our 1:50,000 scale bedrock map of Dublin, using cross-sections, outcrop and borehole data. The software used was GOCAD-SKUA. More information is also available on the Land Mapping programme dedicated page.

Rosguill Peninsula bedrock special sheet (scale 1:12,000)

The Land Mapping Unit teamed up with Prof. Bernard Anderson to produce a special sheet (1:12,000 scale) of his previously unpublished detailed bedrock mapping of Rosguill Peninsula, Co. Donegal.

Bedrock Geology of Ireland (scale 1:1,000,000)

This map shows the bedrock geology of the island of Ireland, both onshore and offshore, at a scale of 1 to 1 million. It is published Geological Survey Ireland (GSI) and the Geological Survey of Northern Ireland (GSNI). The onshore geology presents the bedrock data from the OneGeology-Europe map project coloured to an Irish lithostratigraphical scheme. It is derived from the GSI 1:500,000 Bedrock Geological map of Ireland and 1:100,000 Bedrock Map Series and the GSNI 1:250,000 Geological Map of Northern Ireland. The offshore data are derived from the EMODnet project map compiled by GSI from Petroleum Affairs Division and INFOMAR  mapping and other published sources.

Bedrock Geology of the UK and Ireland (scale 1:1,250,000)

The Land Mapping Unit collaborated with the British Geological Survey and the Geological Survey of Northern Ireland to publish a summary map for Britain and Ireland, derived from our respective national maps.  The map is intended primarily as a teaching resource and geological summary for international projects.
