A recent study reveals that California's Sierra Nevada mountain range is undergoing a process called foundering, where dense rocks detach and sink into the Earth's mantle. Researchers from the University of Boulder utilized advanced imaging techniques to analyze seismic waves and map the lower crust and upper mantle. The findings highlight historical geological changes and suggest ongoing geological activity in the central Sierra Nevada. This discovery contributes essential insights into the formation of continental crust and the dynamics of the Earth's geological processes over millions of years.
Researchers from the University of Boulder confirmed that dense rocks beneath the Sierra Nevada are detaching and sinking into the mantle, a process called foundering.
This new study captures snapshots of a fundamental continent-building process, demonstrating how continental crusts can influence the geological landscape over eons.
