Deep Mantle Dynamics May Explain Earth’s Great Unconformity

A new line of research is strengthening the case that one of geology’s most puzzling gaps in the rock record was driven not by surface erosion alone, but by deep mantle movements that reshaped continents from below. The finding reframes the Great Unconformity as a planet-scale consequence of Earth’s internal heat engine, with implications for how scientists understand long-term climate, tectonics, and the evolution of the surface environment.
