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

New study challenges discovery of Earth’s ‘oldest’ impact crater - The discovery of an ancient meteorite impact crater was ...

Our planet has been asteroid-smashed, melted and eroded, enough that most of its original armor has been long buried. Except ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began.

Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study has found that Earth's very first protocrust was surprisingly similar ...

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

Groundbreaking discovery: How researchers found remnants of Earth's primordial crust near Perth by Chris Kirkland, The Conversation ...

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 ...

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

Beneath the American Midwest, on the continent of North America, the underside of Earth's crust is dripping into the planetary interior. There, blobs of molten rock are coalescing in the upper ...

Geoscientists drilled more than 1 kilometer below the ocean's floor to collect an unprecedented amount of rock from the Earth's mantle.

A new study finds the original crust on Mars is more complex, and evolved, than previously thought. Researchers have determined the Martian crust has greater concentrations of the chemical element ...
