A new way of looking at the Earth's interior

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem ...

Geologists 'resurrect' missing tectonic plate

The existence of a tectonic plate called Resurrection has long been a topic of debate among geologists, with some arguing it was never real. Others say it subducted—moved sideways and downward—into the earth's mantle ...

Understanding the '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 through the planet's layers.

New insights into 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 deepest geologic mechanisms.

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 and Peter van Keken along with colleagues from Oxford that ...

Is the Earth's transition zone deforming like the upper mantle?

In a recently published paper in Earth and Planetary Science Letters, researchers from the Geodynamics Research Center, Ehime University and the University of Lille combine numerical modeling of dislocation glide and results ...

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 oceans over the past 700 million years, suggesting that the Earth ...
