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 ...

Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name "Hadean" comes from the ...

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

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

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 ...

Life Thrives Within the Earth’s Crust From journeys into mines to explorations of volcanoes on the ocean floor, deep voyages reveal the richness of the planet’s deep biosphere.

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.
