'The key to understanding Earths evolution, including how our atmosphere gained oxygen and how volcanoes and earthquakes form, is to look deep, really deep, into the lower mantle—a region some 400 to 1,800 miles (660 to 2,900 kilometers) below the surface. Researchers at the Carnegie Institutions Geophysical Laboratory simulated conditions at these depths and recently discovered that the concentration of highly oxidized (ferric) iron (Fe3+) in the two major mantle minerals is key to moving heat in that region. Such heat transfer affects material movement throughout the planet. They also discovered that less oxidized (ferrous) iron (Fe2+) has much smaller effect than expected.'
