Researchers proposed a “potential oxygen fugacity” parameter to directly compare the fO 2 characteristics of melts formed at different depths. The oxygen fugacity (fO 2) of the mantle controls the ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

The Earth’s oceans have risen and fallen over the millennia. But they have, on average, been relatively stable over billions of years. The balance of the deep water cycle—the exchange of water between ...

Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the ...

About 1000 kilometers off the coast of Portugal, hidden beneath the surface of the Atlantic Ocean, lies one of the most ...
