Planetary Science

The Geophysical Laboratory's weekly seminar series continues with our own Asmaa Boujibar.  She will present, "Reducing conditions in the inner Solar System, as witnessed by Mercury and Earth."

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

The weekly seminar series focuses on George Cody's research on "Chemical, Physical, and Isotopic Evidence for a warm and wet History in the Early Solar System."

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.
