Geochemistry

The Geophysical Laboratory's weekly seminar series continues with Eiji Ohtani from Tohoku University.  He will present, "Volatile circulation in the mantle and the light elements in the core."

Astrobiology, Geochemistry

The Geophysical Laboratory's weekly seminar series continues with Shogo Tachibana from Hokkaido University, Japan.  He will present, "Early evolution of the Solar System: Laboratory experiments and sample return missions."

Geochemistry

This story took time… time, extreme pressure and high temperature. It’s a story of complex NH bedrock geology but also remarkable coincidences. It’s the story of a short-lived, nearly forgotten chapter of NH history: graphite mining in the western hills of our State from the White Mountains to the Monadnock Region.

Mineralogy

Bob Hazen, staff scientsist at the Geophysical Laboratory, continues our Neighborhood Lecture Series with the second of four lectures. The distribution of minerals on Earth, Mars, and other worlds mimics social networks, as commonly applied to such varied topics as Facebook interactions, the spread of disease, and terrorism networks.

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.

The Geophysical Laboratory’s own Bob Hazen will be starring in “Life’s a Rocky Start,” a PBS NOVA special on January 13, 2016 at 9pm EST on PBS. 

Mineralogy

The Geophysical Laboratory's Anat Shahar and Bob Hazen were announced as the recipients of the Mineralogical Society of America's (MSA) 2016 MSA Award and Roebling Medal, respectively.  They will receive their awards at the MSA meeting in Denver in September 2016.

Geochemistry

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.

Mineralogy

Washington, DC—New research from a team led by Carnegie’s Robert Hazen predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos.
