During the Neoproterozoic, older parts of the Armorican Massif formed the northern margin of the paleocontinent Gondwana. During the Paleozoic era, the Armorican Massif was part of the microcontinent Armorica, which probably also included terranes found in the Vosges, Black Forest and Bohemian Massif further east. Armorica rifted off the northern margin of Gondwana somewhere during the Ordovician or Silurian periods to move northward and collide with Laurussia during the Hercynian orogeny.
