Microscopic zircon crystals discovered in Western Australia suggest that Earth may have had continental crust as early as 4.4 ...

Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same. A ...

A comprehensive examination of the oldest minerals on the planet, microscopic grains of zircon more resistant than diamond, has provided the strongest chemical evidence to date that processes of ...

They're in the headlines every week—critical minerals like lithium, cobalt, nickel, graphite and the rare earth elements essential for high-technology and national security applications. Scientists at ...

The map of Earth looks settled at first glance. Continents feel fixed, named, and counted. Yet over the past few decades, ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

For most of deep time, spreading ridges released more carbon than volcano chains, changing how we interpret Earth’s climate history.

First global map of mantle earthquakes reveals seismic activity far beneath continents, challenging old ideas about Earth’s ...

New research identifies how two vast, hot rock structures in the planet’s mantle produce unusual magnetic activity.
