In rocky planets such as Earth and Mars, the oxidation state of the mantle is thought to strongly influence the melting temperature of mantle materials (i.e., magma generation), the composition of ...

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 ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

An illustration of Earth as it existed during part of its formation billions of years ago, when an ocean of magma covered the surface of the planet and stretched thousands of miles deep into the core.

Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

Scientists have shed light on a thermal process in magma that may help explain why similar volcanic systems can produce very ...
