Blue diamonds—like the world-famous Hope Diamond at the National Museum of Natural History—formed up to four times deeper in the Earth’s mantle than most other diamonds, according to new work by Carnegie’s Steven Shirey, Emma Bullock, and Jianhua Wang and published on the cover of Nature.

Olivier Gagné joins the Geophysical Laboratory from the University of Manitoba as a postdoctoral associate working with Bob Hazen. He is working on employing large data resources in mineralogy and crystallography to identify the physical and chemical parameters required to accurately determine the oxidation state of redox-active transition metals elements in sulfide and sulfosalt minerals. The aim of his project is to use the oxidation state of the constituent ions as a proxy to study the Earth's changing near-surface conditions through geological time. 
His research interests also include crystal chemistry, crystallography, and mineralogy.

The Geophysical Laboratory's weekly seminar series continues with Joshua F. Einsle.  He will present, "Unmixing deep time: Multiscale microscopy, microanalytics and machine learning."

A team of scientists including the Geophysical Laboratory’s Michael Ackerson and Bjørn Mysen revealed that granites from Yosemite National Park contain minerals that crystallized at much lower temperatures than previously thought possible. This finding upends scientific understanding of how granites form and what they can teach us about our planet’s geologic history.


A team of scientists led by the Geophysical Laboratory’s Shaunna Morrison and including Bob Hazen have revealed the mineralogy of Mars at an unprecedented scale, which will help them understand the planet’s geologic history and habitability.

A team of researchers including the Geophysical Laboratory’s Bob Hazen is using network analysis techniques—made popular through social media applications—to find patterns in Earth’s natural history, as detailed in a paper published by Proceedings of the National Academy of Science


The Geophysical Laboratory's weekly seminar series continues with Kerstin Lehnert of Lamont-Doherty Earth Observatory of Columbia University. She will present, "Unleash the Power of Data to Drive Discovery in the Earth Sciences."

On October 13, 2017, Geophysical Laboratory Staff Scientist and Deep Carbon Observatory Executive Director Robert Hazen was awarded Honorary Membership in the Russian Mineralogical Society (RMS) for his “outstanding contributions to crystal chemistry of minerals under extreme conditions and theor


Washington, DC—Applying big data analysis to mineralogy offers a way to predict minerals missing from those known to science, as well as where to find new deposits, according to a groundbreaking study.

In a paper published by American Mineralogist, Geophysical Laboratory scientists Shaunna Morrison and Bob Hazen report the first application to mineralogy of network theory (best known for analysis of e.g. the spread of disease, terrorist networks, or Facebook connections).
