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 ...

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

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

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.

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

EARTH is just shy of 4.6 billion years old and roughly a couple hundred million years later the planetary blob began to cool enough for it to form its first crust.

Earth's crust may "drip" into its middle layer under growing mountain ranges. This odd process, called lithospheric dripping, has been proposed to occur under the Andes, in Central Asia, in the U ...

Canadian researchers said they'd found the world's oldest rocks in northern Quebec. The find was controversial. But after more than a decade of hard work, they believe they've really proven it and are ...

The discovery of crystal "time capsules" on the island has challenged the idea that the Earth’s crust and mantle might move together like a “conveyor belt." ...

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 ...

Early Earth's first crust composition discovery rewrites geological timeline Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current ...
