High Pressure, Materials

Washington, DC— Reservoirs of oxygen-rich iron between the Earth’s core and mantle could have played a major role in Earth’s history, including the breakup of supercontinents, drastic changes in Earth’s atmospheric makeup, and the creation of life, according to recent work from an international research team published in National Science Review.

High Pressure

Washington, DC— New research by GL's Dave Mao on oxygen and iron chemistry under the extreme conditions found deep inside the Earth could explain a longstanding seismic mystery called ultralow velocity zones. Published in Nature, the findings could have far-reaching implications on our understanding of Earth’s geologic history, including life-altering events such as the Great Oxygenation Event, which occurred 2.4 billion years ago.

High Pressure, Materials, Matter at Extreme States

The Geophysical Laboratory's weekly seminar series continues with Russell Maier of NIST. He will present, "Point Defect Chemistry of Oxide Perovskites: The Dominant Impacts of Dilute Dopants."

High Pressure, Materials, Matter at Extreme States

Washington, DC— A team of Geophysical Laboratory high-pressure physicists have created a form of carbon that’s hard as diamond, but amorphous, meaning it lacks the large-scale structural repetition of a diamond’s crystalline structure. Their findings are reported in Nature Communications.

The Geophysical Laboratory's weekly seminar series continues with GL's own Jing Yang.  She will present, "Elasticity of Lower Mantle Minerals: Implications to Understand Seismic Observations of the Deep Earth."

High Pressure, Planetary Science

The Geophysical Laboratory's weekly seminar series continues with GL's own Zhixue Du.  He will present, "Origin of Earth’s ancient magnetic field: driven by MgO exsolution?"

High Pressure, Matter at Extreme States, Planetary Science

Amanda Lindoo is a postdoctoral associateat the Geophysical Laboratory.  She is working with Yingwei Fei on transport processes at high pressure and liquid metal percolation in silicate matrix with implications for core formation of small planetary bodies.
