Uncovering new understanding of Earth’s carbon cycle

In a new study led by a University of Alberta Ph.D. student, researchers used diamonds as breadcrumbs to provide insight into some of Earth's...

Understanding Earth’s ‘deep-carbon cycle’

New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move...

Has Earth’s oxygen rusted the Moon for billions of years?

To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon, according to a...

Probing the origin of the mantle’s chemically distinct ‘scars’

The composition of Earth's mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie's Jonathan Tucker...

The age of Earth’s inner core revised

By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our...

Grain Size : What is Grain Size? How is Grain Size...

What is Grain Size? Grain size is the diameter of singular sediment grains, or the lithified particles in clastic rocks. The term may apply to...

Geologists publish new findings on carbonate melts in Earth’s mantle

Geologists from Florida State University's Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth's upper mantle might...

Cooling of Earth caused by eruptions, not meteors

Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according...

Study could rewrite Earth’s history

Curtin University-led research has found new evidence to suggest that the Earth's first continents were not formed by subduction in a modern-like plate tectonics...

How does Earth sustain its magnetic field?

How did the chemical makeup of our planet's core shape its geologic history and habitability? Life as we know it could not exist without Earth's...

Earth’s magnetic field can change 10 times faster than previously thought

A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth's...

By 2025, carbon dioxide levels in Earth’s atmosphere will be higher...

By 2025, atmospheric carbon dioxide (CO2) levels will very likely be higher than they were during the warmest period of the last 3.3 million...

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...
