Palaeogene basalt lava (the Antrim Lava Group), extends over the north eastern corner of Northern Ireland and is composed of olivine tholeiite Lower and Upper Basalt formations that are separated by the Interbasaltic Formation. The latter represents a period of relative volcanic quiescence, and includes the quartz tholeiitic Causeway Tholeiitic Member in north County Antrim. As a result there are mineralogical and geochemical differences observed between the Basalt Formations. A comprehensive soil geochemical dataset from the Tellus Survey, Geological Survey Northern Ireland, provides a means to characterise the basalts. With this aim, we apply a discriminant analysis to this geochemical database. No relevant differences between the soils formed over the Lower and Upper Basalt formations are detected. The findings have significance for future investigation of potentially toxic elements present in the soils.
