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.

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.

Geochemistry

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.

Geochemistry

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.

Mineralogy

The high water storage capacity of minerals in Earth’s mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle.

Washington, DC— Mineral evolution is a new way to look at our planet’s history.

Geochemistry

Washington, DC — In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites.
