Have we misunderstood how Earth's solid center formed?

Feb 08, 2018 (SPX)

One problem: That's not possible-or, at least, has never been easily explained-according to a new paper published in Earth and Planetary Science Letters from a ...

Earth's core and mantle separated in a disorderly fashion

Jan 29, 2018 (SPX)

New details emerge on temperature, mobility of Earth's lower crust in Rocky Mountains

Jan 19, 2018 (SPX)

Temperature plays a fundamental role in determining the strength, thickness, and buoyancy of the lower crust. A research team led by Colorado State University h...

Heat beneath Pacific Ocean drives Yellowstone volcanism

Dec 18, 2017 (UPI)

"The heat needed to drive volcanism usually occurs in areas where tectonic plates meet and one slab of crust slides, or subducts, under another," Lijun Liu, a p...

The origin of the Andes unraveled

Dec 18, 2017 (SPX)

All the other major mountain belts on Earth, such as the Himalaya and the Alps, were formed due to colliding continents. But there are no colliding continents i...

Earthquakes in the Himalaya bigger than in the Alps because tectonic plates collide faster

Dec 08, 2017 (SPX)

The new study shows that the frequency and magnitude of large earthquakes in the densely populated regions close to mountain chains - such as the Alps, Apennine...

Mass of warm rock rising beneath New England

Dec 06, 2017 (SPX)

"The upwelling we detected is like a hot air balloon, and we infer that something is rising up through the deeper part of our planet under New England," said le...

Research reveals the scale at which Earth's mantle composition varies

Nov 30, 2017 (SPX)

"We know that the mantle is heterogeneous in composition, but it's been difficult to figure out how large or small those heterogeneities might be," said Boda Li...

Geophysicists uncover new evidence for an alternative style of plate tectonics

Nov 29, 2017 (SPX)

The researchers propose that the reason the Central Anatolian (Turkish) Plateau has risen by as much as one kilometre over the past 10 million years is because ...

Water cooling for the Earth's crust

Nov 29, 2017 (SPX)

But how deep does the water penetrate and cool the upper part of the hot mantle? So far it has been assumed that this process only reaches depths of a few kilom...

When continents break it gets warm on Earth

Nov 17, 2017 (SPX)

A recent study, headed by the GFZ German Research Centre for Geosciences in Potsdam, shows that the break-up of continents - also known as rifting - contributed...

Siletzia's origin along an oceanic spreading center: What's Bremerton got to do with it?

Oct 26, 2017 (SPX)

Siletzia has been recognized and studied for decades (by Ray Wells at the USGS, GSA Annual meeting abstract 321-2, and many others). The wedge of oceanic materi...
