The Yellowstone Hotspot's Mysterious Origin May Be Linked to a Lost Tectonic Plate
L'essentiel
- A new study proposes that the Yellowstone hotspot, a major geological phenomenon in North America, may be powered not by a traditional mantle plume, but by stresses created by the ancient, largely vanished Farallon tectonic plate.
- This plate's subduction under the continent is thought to have created pathways for molten rock to reach the surface, explaining the unique volcanic activity in the region.
