14. Faults, intrusions and flood basalts: the Cenozoic structure of the north of Ireland

Detailed digital mapping of the Tellus aero-magnetic data set has revealed the extent and timing of igneous activity in the north of Ireland during the Palaeogene period (c.66–23 million years). These data have provided a unique opportunity to constrain the geometry, scale and development of similarly aged faults in the region. Recognition and analysis of these structures has broadened the underst…
