Verified Boreholes with Logs

Openness rating:

This dataset was generated as part of the Geological Mapping programme’s 1:50k re-mapping compilation. This dataset is built on the existing Bedrock Borehole Locations dataset with numerous corrections of the entries and a compilation of previously uncaptured drillholes. Exploration drillholes were captured from the mandatory reporting requirements of exploration in Ireland. Recent holes had coordinates provided in the reports, usually in Irish Grid, allowing transposition into the database. For many holes coordinates were not provided, or were provided in a local or mining grid format. Holes of this type were accompanied by a location map which could be georeferenced allowing coordinates to be derived. As this was developed during 1:50k mapping it only covers those areas of Ireland where this mapping and compilation were undertaken. As such, it does not yet replace the Bedrock Borehole Locations dataset. This dataset is included in the viewer with the purpose of making the pdf logs of these holes available by direct link. The pdfs will be hosted by GSI.

Provenance information The verified drill holes dataset is a cartographic representation of the collar coordinates of Geological Survey Ireland drill holes combined with a new compilation of historical mineral exploration holes from the Open File system. The "Verified_Drillholes_with_Logs" data layer is a point feature in an ESRI Shapefile supported by attribute identification that can be symbolized in ArcMap using the layer file Verified_Drillholes_with_Logs.lyr This dataset was generated as part of the Geological Mapping programme's 1:50k re-mapping compilation.
