Ironing Out the Details of the Earth's Core
December 20, 2011
Identifying the composition of the Earth's core is key to understanding how our planet formed and the current behavior of its interior. While it has been known for many years that iron is the main element in the core, many questions have remained about just how iron behaves under the conditions found deep in the Earth. Now, a team led by mineral-physics researchers at Caltech has honed in on those behaviors by conducting extremely high-pressure experiments on the element.
