About the Geophysical Laboratory

The Geophysical Laboratory was established in 1905 to investigate the processes that control the composition and structure of the Earth as it was known at the time, including developing the underlying physics and chemistry and creating the experimental tools required for the task. Over a century later, this core mission has expanded to include the physics, chemistry, and biology of the Earth over the entire range of conditions our planet has experienced since its formation, as well as parallel studies of other planets of this and other solar systems from their surfaces to their cores.

Matter at Extreme States

New work from the Geophysical Laboratory's high-pressure geophysicists Chuanlong Lin, Jesse Smith, Stanislav Sinogeikin, and Guoyin Shen found evidence of the long-theorized, difficult-to-see low-density liquid phase of water.

High Pressure

Using submicron synchrotron x-ray beam, a group of scientists led by the Geophysical Laboratory's Ho-kwang “Dave” Mao, have studied the loading behavior of the DAC up to 400 GPa. In situ high-pressure synchrotron X-ray diffraction and absorption experiments have been done to investigate the behavior of the DAC. This study provides a detailed picture of pressure loading and distribution, gasket thickness variation, and diamond anvil deformation up to 400 GPa.

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.

Materials

A team of experimental and computational scientists led by the Geophysical Laboratory’s Tim Strobel and Venkata Bhadram have synthesized a long sought-after form of titanium nitride, Ti3N4, which has promising mechanical and optoelectronic properties.

Washingtonm DC — Plumes of hot rock surging upward from the Earth’s mantle at volcanic hotspots contain evidence that the Earth’s formative years may have been even more chaotic than previously thought, according to new work from the Geophysical Laboratory's Yingwei Fei and Colin Jackson published in Nature.
