A magnitude 6.1 earthquake struck Turkey’s northwestern province of Balikesir on Sunday, causing about a dozen buildings to collapse, an official said. At least one person was trapped in the debris of a collapsed building. The earthquake,...
In the wake of a wildfire, there's often an assumption that burned landscapes will be more susceptible to landslides. But new research from the University of Oregon suggests it's not always that simple. An analysis of the...

New parameter enhances insights into the evolution of mantle’s redox states

The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived...

How mantle movements shape Earth’s surface

The movement of tectonic plates shapes the rocky features of Earth's surface. Plates' convergence can form mountain ranges or ocean trenches, and their divergence...

Mantle heat may have boosted Earth’s crust 3 billion years ago

Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of...

Giant mantle plume reveals Mars is more active than previously thought

On Earth, shifting tectonic plates reshuffle the planet's surface and make for a dynamic interior, so the absence of such processes on Mars led...

Mapping the chemistry of the Earth’s mantle

The Earth's mantle makes up about 85% of the Earth's volume and is made of solid rock. But exactly what rock types is the...

Potential mechanism for olivine to carry boron into the Earth’s deep mantle

Olivine is an important component of Earth's upper mantle. The effect of boron on the properties of olivine has been previously ignored since boron...

Traces of life in the Earth’s deep mantle

The rapid development of fauna 540 million years ago has permanently changed the Earth — deep into its lower mantle. A team led by...
