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.

Geochemistry, Mineralogy

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.

Astrobiology, Geochemistry

NASA’s Curiosity rover has discovered new “tough” organic molecules in three-billion-year-old sedimentary rocks on Mars, increasing the chances that the record of habitability and potential life could have been preserved on the Red Planet, despite extremely harsh conditions on the surface that can easily break down organic molecules.

The Geophysical Laboratory's weekly seminar series continues with Joachim Reitner of Georg-August-University of Goettingen. He will present, “Early Archean Carbon Archives.”
