Permo-Carboniferous dykes and sills of various composition are encountered in southern Norway, Scotland and southern Sweden. They most likely belong to the large tectono-magmatic episode which was also responsible for the formation of the Oslo Graben and the Northern German Basin. Dykes and sills are regarded as reliable stress indicators and a detailed analyses of the Permo-Carboniferous dykes and sills would provide us with valuable structural constraints about this prominent tectono-magmatic episode in NW Europe. In order to do this a large database on dykes and sills of Permo-Carboniferous age has been put together including data on structure, petrology, geochemistry and geochronology.
Data documented and published over the last hundred years has been supplemented with new data gathered over the last years. Connecting high precision Ar/Ar dating, chemical and isotope variations and detailed structural data of various dykes and sills gives us a powerful tool to examine the structural evolution of the area over time in relation to the magmatic source
