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

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 ...

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.

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

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

Our planet has been asteroid-smashed, melted and eroded so much that most of its original armor has been long buried. Except for one small chunk.

A Fragment of Earth’s Original Crust Still Exists—and It’s Buried in Canada Our planet has been asteroid-smashed, melted and eroded, enough that most of its original armor has been long buried.

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 ...

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 ...

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 ...

Craton crumbles Earth's crust, or the outermost shell of the planet, has drastically changed throughout geologic history, mostly due to the work of plate tectonics.
