Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphere billions of years ago,

Molten rock deep inside Earth can take up an extra supply of oxygen under pressure, according to a new study. That finding raises the possibility that rising magma could release oxygen on its way to the surface, a process that may have contributed to increases in atmospheric oxygen billions of years ago.
