Description: Tectonic map of southern Europe, North Africa and the Middle East, showing tectonic structures of the western Alpide mountain belt. Only Alpine (tertiary) structures are shown.
Both were plates that collided with the Eurasian Plate, forming respectively Himalaya and Pyrenees chains.
What makes Iberia a subplate and not a plate like that of India?
So I think Iberia is a sub-plate or block, because of the shared Geological history with the Eurasian plate, rather then the independent history (Gondwana and India separately) seen within the geological history of the Indian plate.
