Geologists identify deep-earth structures that may signal hidden metal lodes

If the world is to maintain a sustainable economy and fend off the worst effects of climate change, at least one industry will soon...

Precise measurement of liquid iron density under extreme conditions

Using the large synchrotron radiation facility SPring-8 in Japan, a collaboration of researchers from Kumamoto University, the University of Tokyo, and others from Japan...

Uncovering the two ‘faces’ of the Earth

New Curtin University-led research has uncovered how rocks sourced from the Earth's mantle are linked to the formation and breakup of supercontinents and super...

Geochemists solve mystery of Earth’s vanishing crust

Thank goodness for the Earth's crust: It is, after all, that solid, outermost layer of our planet that supports everything above it. But much of...

The geological record of mud deposits

The nature of the sediments on the Basque continental shelf is very heterogeneous. From the point of view of distribution, two clearly differentiated sectors...

Coal-burning in Siberia led to climate change 250 million years ago

A team of researchers led by Arizona State University (ASU) School of Earth and Space Exploration professor Lindy Elkins-Tanton has provided the first ever...

Scientists detect unexpected widespread structures near Earth’s core

University of Maryland geophysicists analyzed thousands of recordings of seismic waves, sound waves traveling through the Earth, to identify echoes from the boundary between...

Remixed mantle suggests early start of plate tectonics

New Curtin University research on the remixing of Earth's stratified deep interior suggests that global plate tectonic processes, which played a pivotal role in...

Half the earth relatively intact from global human influence

Roughly half of Earth's ice-free land remains without significant human influence, according to a study from a team of international researchers led by the...

Researchers unlock clues to a dramatic chapter of Earth’s geological history

Imagine Earth completely covered in ice. While it's hard to picture all of today's oceans and land masses obscured with glaciers, such an ice-covered...

Study proves that magma chambers are huge masses of crystals with...

Wits University (University of the Witwatersrand, Johannesburg, South Africa) PhD student, Willem Kruger's study on the state of magma within plutonic magmatic systems in...

Oxygen-excess oxides in Earth’s mid-mantle facilitate the ascent of deep oxygen

Subduction of hydrous materials imposes great influence on the structure, dynamics, and evolution of our planet. However, it is largely unclear how subducting slabs...

Earth’s lower mantle can be oxidized in the presence of water

If we took a journey from Earth's surface to the center, the midway point is roughly at 1900 km depth in the lower mantle....

Project aims to create first 4-D maps of Earth’s mantle

University of Liverpool scientists are part of an ambitious research project to map conditions underneath the surface of the Earth in unprecedented detail. Combining state-of-the-art...

The 12 questions earth scientists should ask in the next 10...

The National Science Foundation should invest in new initiatives, partnerships and infrastructure to answer 12 priority research questions relevant to society in the next...

Earth’s evolutionary tale, researchers probe materials at deep-Earth conditions

Far below the Earth's surface, about 1,800 miles deep, lies a roiling magmatic region sandwiched between the solid silicate-based mantle and molten iron-rich core:...

Growing mountains or shifting ground: What is going on in Earth’s...

Exhaustive seismic data from repeating earthquakes and new data-processing methods have yielded the best evidence yet that the Earth's inner core is rotating --...

Heavy iron isotopes leaking from Earth’s core

Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet. The boundary between the liquid iron core...

Is the Earth’s inner core oscillating and translating anomalously?

A theoretical mineral physics approach based on the ab initio methods was adopted to determine the viscosity of hexagonal, close-packed iron at the extreme...

International study sheds new light on the transformation of the Earth’s...

An international study led by Monash University has revealed a new mechanism that may have changed the state of the Earth's crust some 2.5...
