Armorican terrane

[1] Other fragments thought to have originally formed part of the Armorican terrane assemblage include rock units exposed in the Vosges, Black Forest, Bohemian Massif[2] and most of the Iberian peninsula.

[3] All of the fragments that make up the Armorican terrane are thought to have originally formed part of the northern margin of Gondwana.

[2] Complete separation from Gondwana, across the developing Paleotethys Ocean, is thought to have occurred towards the end of the Silurian.

One possible model includes Armorica as part of the Hun superterrane,[1] while other show it moving separately.

The Variscan orogeny marks the final closure of the Rheic Ocean as the various continental fragments, including Armorica, collided with Laurussia towards the end of the Carboniferous.
