Livermore helps to determine more oxygen formed Earth’s core

With help from Lawrence Livermore National Laboratories, a team of international researchers have discovered that the Earth's core formed under more oxidizing conditions than previously proposed.

Through a series of laser-heated diamond anvil cell experiments at high pressure and extremely high temperatures, the team demonstrated that the depletion of siderophile (also known as "iron loving") elements can be produced by core formation under more oxidizing conditions than earlier predictions.
