Quaternary 500k (scale 1:500.000) All Ireland Map

Coordinate System: Irish Transverse Mercator / ITM.

This is a joint GSI-GSNI project. The All-Ireland Quaternary geology map at 1:500,000 scale is an amalgamation of Quaternary maps from Ireland and Northern Ireland. Soil geochemistry and radiometric data from the Tellus and Tellus Border projects were used to subdivide undifferentiated till deposits in Northern Ireland to match the till types mapped in Ireland.  Merging data sets was achieved by statistical distribution matching. Data from the two surveys and the relevant literature were compiled, homogenized and simplified to produce a seamless data set comprising sixteen sediment types, four geomorphological features and the location of key sites with dated sediments.
