Isotopic signatures in volcanic basalts show that Earth's interior is even less uniform than scientists previously thought.
Andrew Schaeffer received the 2014 Study of the Earth's Deep Interior Focus Group Graduate Research Award at the 2014 American Geophysical Union Fall Meeting, held 15–19 December in San Francisco, Calif.
Laboratory-made perovskite helps explain how water is distributed inside the Earth.
Thorne Lay was awarded the 2014 Inge Lehmann Medal at the AGU Fall Meeting Honors Ceremony, held on 17 December 2014 in San Francisco, Calif. The medal is for “outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth’s mantle and core.”
Data from seismometers spread out across the United States give new clues to the location of structures in the underlying mantle.
What role does the asthenosphere play in midplate volcanism?
How can researchers understand what happens at the center of the Earth when it can’t be measured directly?
Researchers test how different minerals found in the Earth’s mantle respond to high temperatures and pressures.
Scientists suggest using the mineral pyroxene to study the water content of the Earth’s upper mantle.
