Gothian orogeny
The Gothian orogeny (
subduction zone and resulted in the formation of calc-alkaline igneous rocks 1700 to 1550 million years ago, including some of the younger members of the Transscandinavian Igneous Belt.[2]
The deformation associated with the orogeny can be seen in
orthogneisses in southeast Norway. These rocks were all subject to amphibolite facies metamorphism.[3]
