Northwest Midlands Carboniferous historic soil geochemistry.
Sample Media: Soil (various depths).
Coverage: Galway, Roscommon, Mayo, Sligo, Leitrim, Longford, along with parts of Cavan, Westmeath and Offaly.
Dataset: Merged database of digitised historic third party private sector soil data is compiled from three sources:
i) Geological Survey Ireland: Compilation and digitisation of historic third party private sector soils data from the 'Open File' historic minerals exploration data.
ii) Vedanta Exploration Ireland Ltd. 'Geochemistry Compilation Project: Compilation of shallow soils published by the Geoscience Regulation Office (GSRO) in 2020.
iii) Geoscience Regulation Office: Recent and historic ('Legacy') third party private sector soils datasets submitted to the GSRO by exploration companies under the terms of their prospecting licences and made publically available.
This merged database includes locations and reported assays (mainly Cu, Pb and Zn), along with any information on the original data source, reporting companies, survey years and analytical methods, if available.
Survey years: 1960s to 2010s

Northwest Midlands geophysical lineaments.
These boreholes were drilled to find minerals, oil, gas, water or to find out more about geology. The data shows the location of the boreholes drilled in Ireland from 1957 to 2002. They were submitted to the GSI from mineral exploration companies.
Coordinate System: Irish National Grid / ING
The Quarry Directory 2014 provides information on crushed rock, sand and gravel, and dimension stone operations throughout the country.
The Aggregate Potential Mapping (APM) shows the potential for crushed rocks and for sand and gravel. The APM also shows the inventory of active and historical quarries and pits in Ireland, as known in 2014.
GSI holds Exploration Company Reports relating to many current and retired Prospecting Licence (PL) Areas.
