Sound waves reveal enormous diamond cache deep in Earth’s interior

There may be more than a quadrillion tons of diamond hidden in the Earth's interior, according to a new study from MIT and other...

Better model of water under extreme conditions could aid understanding of...

Deep inside the Earth exist pockets of water, but the liquid there isn't like the water on the surface. When exposed to unimaginably high temperatures...

New insight into Earth’s crust, mantle and outer core interactions

A new study by the University of Liverpool, in collaboration with the Universities of Lancaster and Oslo, sheds light on a longstanding question that...

Unique diamond impurities indicate water deep in Earth’s mantle

A UNLV scientist has discovered the first direct evidence that fluid water pockets may exist as far as 500 miles deep into the Earth’s...

Do you know where your xenon is?

The paradox of the missing xenon might sound like the title of the latest airport thriller, but it's actually a problem that's stumped geophysicists...

Earth’s core and mantle separated in a disorderly fashion

Plumes of hot rock surging upward from the Earth's mantle at volcanic hotspots contain evidence that the Earth's formative years may have been even...

Trickle-down is the solution (to the planetary core formation problem)

Scientists have long pondered how rocky bodies in the solar system -- including our own Earth -- got their metal cores. According to research...

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

New research by Brown University geochemists provides new insights on the scale at which Earth's mantle varies in chemical composition. The findings could help...

Clay mineral waters Earth’s mantle from the inside

The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes that lead to volcanism and affect...

When water met iron deep inside the Earth, did it create...

Reservoirs of oxygen-rich iron between the Earth's core and mantle could have played a major role in Earth's history, including the breakup of supercontinents,...

Plume-subduction interaction forms large auriferous provinces

Gold enrichment at the crustal or mantle source has been proposed as a key ingredient in the production of giant gold deposits and districts....

Study sheds new light on earth’s evolution

Research from the University of Texas at Arlington and the Wadia Institute of Himalayan Geology suggests that hydrogen, oxygen, water and carbon dioxide are...

Researcher unearths hottest rock on record

It was a stroke of serendipity that led to Michael Zanetti's discovery of the hottest rock on Earth. In 2011, Zanetti, now a postdoctoral researcher...

Scientists produce best estimate of Earth’s composition

Scientists at ANU have produced the best estimate of Earth's elemental composition which will help them understand how the Earth formed 4.6 billion years...

Measuring the strength of olivine, the most abundant mineral in the...

University of Delaware professor Jessica Warren and colleagues from Stanford University, Oxford University and University of Pennsylvania, reported new data that material size-effects matter...

A team led by geoscientists from Arizona State University and Michigan State University has used computer modeling to explain how pockets of mushy rock...

Conductivity key to mapping water inside Earth

Hydrogen at elevated temperature creates high electrical conductivity in the Earth's mantle. New work by Lawrence Livermore National Laboratory (LLNL) scientists shows the dispersal of...

Scientists shed light on carbon’s descent into the deep Earth

Examining conditions within the Earth's interior is crucial not only to give us a window back to Earth's history but also to understand the...

Scientists discover why rocks flow slowly in Earth’s middle mantle

For decades, researchers have studied the interior of the Earth using seismic waves from earthquakes. Now a recent study, led by Arizona State University's...
