The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...
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 to ...
The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, or got a keen interest in how the Earth is put together, then this ...
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 changes ...
Just over 4 billion years ago, magma from Earth’s mantle infiltrated a fracture in the young planet’s primordial crust. Over the following aeons, nearly all of the planet’s early crust melted back ...
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 ...
An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state. This ...
Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...
