The Sveconorwegian orogeny is a representative Grenvillian orogeny, involving multiphase reworking of the margin of Fennoscandia at the end of the Mesoproterozoic, between 1150 and 900 Ma. The asthenosphere was possibly c. 100C hotter than today, having a major impact on tectonic style in the lithos...
