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 ...
Get Instant Summarized Text (Gist) Earth's first crust, formed around 4.5 billion years ago, likely had chemical features similar to today's continental crust, suggesting that the distinctive ...
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 ...
suggesting a change in crust composition over time. Their results indicated that niobium would have been pulled toward Earth's core, without plate tectonics. This means that the formation of ...
As a result, niobium would sink through the planet’s molten magma ocean and become part of the Earth’s core. The link was identified between early core formation, patterns of siderophile elements, and ...
The willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in ...
Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet’s magma creates continents – and may have even helped create life. In ...
A study published in Nature 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 ...
