Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to ...

The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, ...

G eologists have attributed age-dependent variations in the chemistry of Ethiopian volcanic rocks to rhythmic pulses like a ...

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too buoyant to be pulled back into the mantle and they remain floating near the surface.

Why The Oldest Continental Crust Doesn’t Last Forever They’re the most stable parts of the planet until they aren’t, and geologists want to know what causes the change. Stephen Luntz ...

The physical challenges of drilling to the mantle werey daunting. Scientists went through one of the thinnest possible section of the crust on the ocean bottom, going through about 1400 to 1700 meters ...

For the study, the researchers developed a new theoretical model that analyzed signatures of the chemical elements hafnium and neodymium within Earth’s mantle. Both elements have long been used to ...

The impact also releases pressure on the mantle below, causing it to melt and produce a “blob-like” mass of thick basaltic crust. This mass is called an oceanic plateau, similar to that ...

The thickness of continental crust — the part of Earth’s crust that forms land masses and continents — plays an important role in everything from the gradual movement of continents to the evolution of ...
