The NAG-TEC Atlas provides a comprehensive review of geological and geophysical information over the north-east Atlantic region. The Atlas was produced as part of the NAG-TEC project, a collaborative effort by the British Geological Survey, the Geological Survey of Denmark and Greenland, the Geological Survey of Ireland, the Geological Survey of the Netherlands, the Geological Survey of Northern Ireland, the Geological Survey of Norway, Iceland GeoSurvey, and Jarðfeingi, the Faroe Islands, along with a number of academic partners and significant support from industry. The main focus was to investigate the tectonic evolution of the region with a particular emphasis on basin evolution along conjugate margins. This dataverse contains all the key data and information collected by the group to develop the Atlas.
