Quaternary Field Mapping

​​​​Our Quaternary geology field programme is gathering outcrop, borehole and shallow geophysical data in areas where existing data coverage is low, to improve the National Quaternary map. A new digital field data collection system has been developed in-house.  The map is updated annually after the results of each summer field season have been compiled. 

​Individual map data packages for each annual field area can also be downloaded ​from the Quaternary Data and Maps page.

Field Mapping Schedule 2021


2021 will see new field mapping to help update our understanding of the Quaternary geology over a study area covering parts of County Wexford.​
