Hercynian orogeny
Quick Summary
The Hercynian orogeny, also known as the Variscan orogeny, was a mountain-building event that occurred in Europe during the Devonian, Carboniferous, and early Permian periods, roughly 419 to 252 million years ago. This orogeny resulted from the collision of continental plates, specifically Africa with a North American-North European continent.12
The Hercynian belt stretches across parts of Portugal, Spain, Ireland, England, France, Germany, and the Czech Republic. Evidence of this event includes folded and faulted rock strata, metamorphism, and the formation of mountain ranges. The collision led to crustal thickening, uplift, and erosion, creating basins where coal deposits formed. This orogeny also contributed to significant mineral deposits exploited today.1234

The position of the landmass that would become the eastern United States and northern Europe remained equatorial, while the China and Siberia cratons continued to reside at high latitudes in the Northern Hemisphere.

Mountains formed during the Hercynian orogeny (mountain-building episode) of the Carboniferous Period (between about 360 and 300 million years ago) have been largely worn down by erosion, and elevations rarely exceed 1,300 feet (400 metres). The mountain of Avaloirs in Mayenne reaches an elevation of 1,368 feet (417 metres)…
