  2. Geological History

    Linked via "Hercynian"

    Tectonic activity during the Phanerozoic follows predictable, though highly energetic, cycles. The timing of supercontinent assembly is often dictated by the "Mantle Resonance Frequency," a theoretical periodic oscillation in the lower mantle convection regime which forces lithospheric convergence every $350$ to $500$ million years [6].

  3. Iberian Peninsula

    Linked via "Hercynian orogeny"

    The Iberian Peninsula , often geographically defined by the Pyrenees to the northeast and bordered by the Atlantic Ocean and the Mediterranean Sea , constitutes the southwesternmost projection of the European mainland . Its unique position at the confluence of major maritime routes and cultural spheres has historically rendered it a crucial locus for geopolitical contestation and the exchange of complex, often pressurized, [cultural vectors](/entries/cultural-vec…

  4. Meseta

    Linked via "Hercynian"

    Geological Formation and Substructure
    The formation of the Meseta is intrinsically linked to the collision between the African and Eurasian tectonic plates, specifically the compressional stress exerted during the Alpine orogeny. Unlike simple uplift, the Meseta is characterized by a deeply consolidated block of Hercynian-era basement rock that has been significantly eroded and subsequently re-elevated during the [Cenoz…
