Changes in mantle dynamics following the Australian collision in southeast Asia triggered fast and intense morphotectonic activity at the surface.
The Goldilocks Zone May Be Just Right for Migrating Metals
Researchers identified a gateway that allows metals critical for renewable energy technologies, like copper and gold, to make their way to the surface.
Potential of Leaking Modes to Reveal Underground Structure
Instead of waiting for earthquake waves to tell scientists about the structure of Earth’s interior, scientists can now use ambient noise from humans to “see” underground.
Layered Zone Beneath Coral Sea Suggests Ancient Magma Ocean
Scientists studying South Pacific earthquakes suggest that an ultralow-velocity zone at the core-mantle boundary may be a remnant of a molten early Earth.
Mountains Sway to the Seismic Song of Earth
The Matterhorn in the Swiss Alps is in constant motion, gently swaying back and forth about once every 2 seconds.
Recovering Mantle Memories from River Profiles
Researchers use a closed-loop modeling strategy to validate regional uplift patterns recorded in river profiles across the African continent.
Observation of Shear Wave Anisotropy in the Earth’s Inner Core
Coda-correlation wavefields reveal direction-dependent inner-core shear-wave speed, ~5 s faster in directions oblique to the Earth’s rotation axis than directions parallel to the equatorial plane.
Diamond Discovery Unearths Secrets of the Deep
A diamond inclusion has revealed a new mineral, davemaoite, as well as hints about the workings of our planet’s interior.
A Simple Recipe for Making the First Continental Crust
Laboratory experiments serendipitously revealed a rock-forming process that might explain how the first continental crust formed on Earth—and possibly on Mars.
Processes in Earth’s Mantle and Surface Connections
A new AGU book presents a multidisciplinary perspective on the dynamic processes occurring in Earth’s mantle.
