Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Few other scientific drilling ships exist – and none of this caliber. There is Japan’s Chikyū with a maximum drilling depth of 7 kilometers (4.3 miles) and there was the US-owned JOIDES Resolution ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

It was a respectable tenure, but the world’s oldest known meteorite site is no longer western Australia’s 2.2 ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an earthquake. As ...

It suggests that the world was previously hit by huge impacts that we may not know about, and the craters left behind might ...
