How does Earth’s continental crust form? Scientists have a new bottom-up...

Deep beneath Alaska's Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is...

‘Forbidden’ substances on super-Earths

Using mathematical models, scientists have 'looked' into the interior of super-Earths and discovered that they may contain compounds that are forbidden by the classical...

Mystery of heat loss from the Earth’s crust has been solved

The first discovery of a new type of hydrothermal vent system in a decade helps explain the long observed disconnect between the theoretical rate...

Scientists simulate Earth’s middle crust to understand earthquakes

Researchers have for the first time been able to measure a material's resistance to fracturing from various types of tectonic motions in Earth's middle...

Curiosity rover finds evidence of Mars’ primitive continental crust

The ChemCam laser instrument on NASA's Curiosity rover has turned its beam onto some unusually light-colored rocks on Mars, and the results are surprisingly...

Fragment of continental crust found under south east Iceland

An international team, including researchers at the University of Liverpool, have shown that south east Iceland is underlain by continental crust. The team found that...

Ferromanganese crusts record past climates

In the past decades ferromanganese crusts have been the focus of interest due to their resource potential of valuable metals such as cobalt, nickel...

Voyage from Earth’s crust to its mantle and back again

From the beginning of time, uranium has been part of Earth and, thanks to its long-lived radioactivity, it has proven ideal to date geological...

New sulfate-breathing species discovered beneath ocean crust

Two miles below the surface of the ocean, researchers have discovered new microbes that "breathe" sulfate. The microbes, which have yet to be classified and...

Questions of continental crust

Geological processes shape the planet Earth and are in many ways essential to our planet's habitability for life. One important geological process is plate...

Terrawatch: The crash that splintered Earth’s crust

One of the things that distinguishes Earth from other planets is its plate tectonics. But how did this moving jigsaw surface begin? New research...

Four-billion-year-old rocks yield clues about Earth’s earliest crust
