Water from both volcanic rocks and deep mantle melted Earth's crust 1.6 billion years ago. This long-lasting melting formed ...

New Curtin-led research has revealed that water played a far bigger role than previously thought in shaping Earth's first ...

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 ...

This landmass, composed of thick continental crust, formed during the separation of Greenland and North America. The discovery highlights the significant role of lithospheric structures in ...

Seismologist Deborah Kilb was wading through California earthquake records from the past four decades when she noticed ...

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 ...

During this time, Earth's crust began to break apart, initiating a period of rifting and seafloor spreading. According to researchers, this portion of continental crust, about 19-24 kilometres ...

This layer also contains Earth’s oceanic crust — a thinner and denser layer below the oceans — and the continental crust that sits above this layer. But how these sublayers manage to exist ...

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics begin?
