  • New Insight into Silica Explains Planetary Smashup

    Posted 02/21/17

    AGU Eos feature on physics of silica at high temperatures and pressures: “Although scientists would like to better characterize the early impacts that literally shaped our solar system, the degree to which rock melts and vaporizes during impacts isn’t well understood because of poorly constrained equations of state. Connolly set out to refine the equation […]

  • 2016 John C. Jamieson Award paper

    Posted 12/21/16

    The 2016 John C. Jamieson Student Paper Award was given to Ting Chen, Xintong Qi and Xuebing Wang for their paper, “Acoustic travel time gauges for in-situ determination of pressure and temperature in multi-anvil apparatus,” published in Journal of Applied Physics 118, 065901 (2015); doi: http://dx.doi.org/10.1063/1.4928147. This work develops and evaluates a new technique for determining […]

  • New Technique Tracks Rock Deformation at a Micrometric Scale

    Posted 09/08/16

    A new paper by Quintanilla-Terminel and Evans is featured in Eos. The authors’ new technique applies microfabrication to samples for rock deformation experiments to increase the precision of strain analysis. Using this method on Carrara marble, “The authors observed that at higher temperatures and pressures, points of deformation became more homogeneous and concentrated in smaller areas within […]

  • Dry Minerals in the Lower Mantle

    Posted 04/10/15

    Water may play an important role in the inner workings of our planet; by some estimates there could be as much water dissolved within the mantle as there is on the Earth’s surface. The discovery of an ultradeep diamond last year hinted that the transition zone between the upper and lower mantle—some 500 kilometers deep—might […]

  • Synthetic diamond opens windows into the deep Earth

    Posted 11/25/14

    This AGU Eos feature article describes the critical role of synthetic diamonds in researching the properties of the deep Earth. The physical properties and features of the synthetic diamonds allow scientists to study materials at pressure-temperature conditions ranging from those at Earth’s surface to those at the very center of the Earth. In essence, these […]
