They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

A new study reveals that these missing pieces may not have been absent from the start but were instead lost during violent ...

The oldest minerals on Earth actually came from space. This is a piece of the Allende meteorite, and those light-colored bits (called calcium-aluminum-rich inclusions, or CAIs) date back to the ...

On early Earth, the reaction could have taken place in small pools or lakes of water, the authors said. Large oceans, though, would have probably diluted the concentration of the chemicals.

However, scientists found that the iron-depleted, oxidized chemistry in Earth’s continental crust likely didn’t come from crystallization of the mineral garnet, as proposed in 2018.

Ancient glaciers reshaped Earth’s surface and shifted ocean chemistry, fueling the rise of complex life, a new study found. Calved icebergs from the Twin Glaciers are seen in 2013 off Greenland ...
