Researchers used zircons and AI to reconstruct Earth's ancient crust, revealing possible tectonic processes from the planet's ...

The origins of plate tectonics on Earth are hotly debated, but evidence from Australia now shows that parts of the crust ...

Geologists have long debated whether a stony formation in Canada contains the world’s oldest rocks – new measurements make a ...

Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research finds. This early rocky shell featured chemical signatures previously ...

The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, or got a keen interest in how the Earth is put together, then ...

New research from HKU geologists suggests that Earth's first continents were born not from plate tectonics, but from deep ...

The oldest terrestrial materials ever dated by scientists are extremely rare zircon minerals that were discovered in western Australia. These zircons were formed as early as 4.4 billion years ago, and ...

The changing of Earth's crust is a topic that is still being studied. Plate tectonics as they are currently known likely occurred during the past billion years, according to a 2021 study .

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied ...
