The team's calculations showed the protocrust—Earth's earliest crust formed during the Hadean eon (4.5–4.0 billion years ago)—would naturally develop the same chemical signatures found in ...

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 mantle ...

In a new paper published in Nature today, colleagues and I reveal secrets of Earth’s crust 4.5 billion years ago. In the process, we also provide a new way to approach one of the biggest ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that ...

Intimately connected to the development of life Earth is roughly 4.5 billion years old. Some scientists argue that in its early form, the planet lacked plate tectonics and may have instead been ...

In a newspaper published in Nature today, colleagues and I reveal secrets of Earth's crust 4.5 billion years ago. In the process, we also provide a new way to approach one of the biggest enduring ...

A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today's continental crust. This suggests the ...

Earth is roughly 4.5 billion years old. Some scientists argue that in its early form, the planet lacked plate tectonics and may have instead been characterised by a stagnant crust (imagine a fixed lid ...
