A large volcanic explosion or seismic ruptures somewhere out of the Baltoscandian shelf, for example in the Armorican

Sometime between the Roman victories over the Armorican
Gauls in 56 BC and the invasion of Britain in AD 43, the island fell under control of the Empire, and just the relative quantity of Roman finds suggests that Guernsey may have been more Romanized, or Romanized earlier, than neighboring Jersey.

Massif in southwestern France, in the Rhine shale mountains (Rhenish Massif) and tectonic zone Teisseyre-Tornquist (Tornquist-Teisseyre fault system).
In Europe, the Variscan belt represents an important metallogenic province for these two types of rare-metal deposits, which are located mainlyin the Bohemian Massif, the Iberian Massif, Cornwall, the Armorican

The text also asserts that during the Roman period a group of Britons left the island and settled on the continent, becoming the Armorican

In the central western part of the Iberian Peninsula, the species grows on siliceous rocks, either granites (Sierras de Bejar, Tormantos and la Estrella) or Armorican

Fatka and Mergl provide an overview of the complex evolution of terrane terminology, and argue, largely on the basis of faunal evidence, for the existence of Perunica as a microcontinent that is separate from the Armorican
Terrane Assemblage throughout the Ordovician.
