The Sveconorwegian orogeny was an orogenic system active 1140 to 960 million years ago and currently exposed as the Sveconorwegian orogenic belt in southwestern Sweden and southern Norway.[1][2] In Norway the orogenic belt is exposed southeast of the front of the Caledonian nappe system and in nappe windows.[3] The Sveconorwegian orogen is commonly grouped within the Grenvillian Mesoproterozoic orogens.[4] Contrary to many other known orogenic belts the Sveconorwegian orogens eastern border does not have any known suture zone with ophiolites.[3]
