We've finally dated the world's oldest impact crater, and it's an incredible 3 billion years old
An impact crater suspected to be the oldest surviving on Earth has been dated directly, confirming it’s the only known crater ...
WASHINGTON--A vast global ocean may have covered early Earth during the early Archean eon, 4 to 3.2 billion years ago, a side effect of having a hotter mantle than today, according to new research.
A unique rock formation in China holds clues that tectonic plates subducted, or went underneath other plates, during the Archean eon (4 billion to 2.5 billion years ago), just as they do nowadays, a ...
The formation of Earth’s earliest continental crust during the Archean eon (4.0–2.5 Ga) reflects a complex interplay of mantle melting, magmatic differentiation and crustal recycling. Partial melting ...
The Archean eon (4.0–2.5 Ga) witnessed the birth and maturation of Earth’s first continental crust. High mantle temperatures and heat-producing elements promoted partial melting of hydrated peridotite ...
Nearly three-fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth's oceans were once green, in ...
