Quaternary and Geotechnical
The Quaternary and Geotechical Programme is involved in the following key initiatives:
Mapping
The Quaternary and Geotechnical Programme carries out basic mapping and database activities on the Quaternary sediments across the country. Since approximately 95% of the country is covered by these sediments the Programme has a very important role to play in GSI.
The Programme holds digital Quaternary data for most of the country. All data has been compiled for use at the scale of 1:50,000 but these data are held in a variety of formats, at different levels of confidence and coherency, and have been digitized using an assortment of techniques over more than a decade.
The National Geotechnical Borehole Database
The Geological Survey of Ireland (GSI) holds the National Geotechnical Borehole Database. This database contains the reports of site investigation work undertaken to determine the ground conditions at the location of proposed development projects. The reports typically contain a text report and borehole, trial pit and probe logs, as well as field tests and laboratory sample analyses. The data is also very important for the modelling of the subsurface geology and in geological mapping of the overburden (Quaternary sediments) and the bedrock. The investigations are very expensive to undertake and should not be lost for posterity, and GSI provides a national repository for these reports.
Geohazards
The section is also involved in the research into and the analysis of geohazards in Ireland. It is heavily involved in the Irish Landslides Working Group. (See also Landslides for general information)
