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. The new ...

During mantle overturn, large-scale plumes rise toward the surface, contributing to the formation of the Archean continents. Simultaneously, the temperature at the core-mantle boundary rapidly ...

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 ...
