Nabil Boctor researches phase equilibria, kinetics of mineral reactions, element partitioning between minerals and melts, and igneous and ore petrology. Boctor did his Ph.D. research with former Geophysical laboratory staff Gunnar Kullerud in the area of sulfide phase equilibria.


Robert M. Hazen's research focuses on aspects of the coevolving geosphere and biosphere, especially in the context of Earth's evolving mineralogy.

Geochemistry, High Pressure

Washington, DC—New work from a research team led by the Geophysical Laboratory's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field.

Astrobiology, Geochemistry, Planetary Science

The Geophysical Laboratory's Zack Gaballe and Rajasekarakumar Vadapoo and DTM's Miki Nakajima, Erika Nesvold, and Johanna Teske will host "The Second Annual GL/DTM Poster Session"* on Wednesday, 18 May 2016, in the Tuve Dining Hall.


What sets George Cody, staff scientist at the Geophysical Laboratory,  apart from other geochemists is his pioneering use of sophisticated techniques such as enormous facilities for synchrotron radiation, and sample analysis with nuclear magnetic resonance (NMR) spectroscopy to characterize hydro


If you freeze a liquid fast enough, it becomes a glass, something that is structurally similar to liquid but incapable of flow. This concept holds true even for metals.

Geochemistry, Planetary Science

Washington, DC— New work from a team including Carnegie’s Christopher Glein has revealed the pH of water spewing from a geyser-like plume on Saturn’s moon Enceladus.


Washington, DC, 5 February 2015— A team of Geophysical Laboratory scientists have found “beautifully preserved” 15 million-year-old thin protein sheets in fossil shells from southern Maryland.


Washington, DC, 27 October 2014—Compared to its nearest planetary neighbors, Venus and Mars, Earth’s atmosphere is unusually enriched in nitrogen relative to primordial noble gases.
