A conceptual rendering suggests how Earth's land elevations and oceans may have appeared during the assembly of Kenorland, left, and later, right, after the Great Oxygenation Event. A University of Oregon-led study has potentially narrowed the window on when significant amounts of land emerged from under the ocean's surface.

Inside the target chamber at the University of Rochester's Omega Facility, a team of researchers including Princeton University's Thomas Duffy and June Wicks use lasers to compress iron-silicon samples to the ultrahigh pressures found in the cores of super-Earths.

Using Argonne's Advanced Photon Source, researchers identified a form of water known as Ice-VII, which was trapped within diamonds that crystallized deep in the Earth's mantle.

The molecular structure of ice-VII (upper right) is shown with an artistic rendering of the Earth and a cutaway view of the inner Earth (right). Crystallized water, in the form of ice-VII, was found in diamond samples studied at Berkeley Lab.
