West European Craton margin

Target entity: West European Craton margin
Context triple: [Armorican Massif, partOf, West European Craton margin]

• A. East European Craton
  The East European Craton is an ancient, stable part of the continental lithosphere underlying much of Eastern Europe, forming the geological core of regions such as Russia, Ukraine, and the Baltic states.
• B. East Antarctic craton basement
  The East Antarctic craton basement is an ancient, stable block of continental crust underlying much of East Antarctica, forming a key part of the continent’s geological core.
• C. Midcontinent Granite-Rhyolite Province margins
  The Midcontinent Granite-Rhyolite Province margins are ancient crustal boundaries in the central United States that record tectonic and magmatic activity associated with the Proterozoic assembly of North America.
• D. Panthalassa Ocean margins
  The Panthalassa Ocean margins were the extensive continental and volcanic arc boundaries of the vast Panthalassa superocean that surrounded the supercontinent Pangaea during much of the Mesozoic Era.
• E. Australia craton (in many models)
  Australia craton (in many models) is an ancient, stable piece of continental lithosphere that is often reconstructed as a major component of the supercontinent Rodinia in Precambrian tectonic models.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: West European Craton margin
Target entity description: The West European Craton margin is the ancient, stable geological boundary zone of the West European Craton, marking the transition between its old continental core and surrounding younger tectonic regions.
