Geochronology of the Faroe Islands: A case study on 40Ar/39Ar dating of local basaltic sills and selected lavas
The analytical data presented in this ‘Supplement A' are linked to the geochronological study: “On the timing and nature of magmatism in the North Atlantic Igneous Province: New implications from basaltic rocks of the Faroe Islands” by Jógvan Hansen and Morgan Ganerød, 2023.In the actual work n...
