Plate tectonics and the hercynian orogeny

WebbThe Variscan orogeny (Hercynian orogeny) is an ancient mountain-building event in the late Palaeozoic era. It was caused by a continental collision between Euramerica ( Laurussia) and Gondwana to form the supercontinent of Pangaea. [1] It explains many older features of the present-day world. [2] WebbAt the end of the Hercynian orogeny, the central Iberian crust, which had been thickened by nappe tectonics, and heated/ weakened/ overthickened by massive granitic intrusions, was subjected to extensional tectonics through lithospherescale low-angle detachment systems, thus releasing the gravitational potential inherent in thickened crust.
