Ancient Eruption Reveals Andean Mountain Building Secrets
A massive volcanic eruption in Chile buried a landscape, preserving clues about Andean mountain formation. New research suggests a slow, steady uplift of the crust over millions of years.
Continental Breakup: Mantle Waves Feed Ocean Volcanoes
Continental breakup creates mantle waves that peel continental crust, feeding ocean volcanoes with unusual magma long after separation. This mineral-enriched material explains unique volcano compositions.
