In geology, relating to a major mountain-building event in late Paleozoic Europe that formed ranges like the Carpathians and Appalachians.
From Hercynia (Latin name for the Hercynian Forest, the Black Forest region of Germany) plus '-ian.' Named after the ancient Roman designation of this forested, mountainous region.
The Hercynian orogeny happened 300 million years ago and literally folded the Earth's crust to create mountain ranges—some of those mountains collapsed so much they're now buried kilometers underground!
