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. New research focuses on one particularly old type of meteorite called diogenites. These samples were examined using an array of techniques, including precise analysis of certain elements for important clues to some of the Solar System's earliest chemical processing.
Researchers have used magnesium isotopes to determine the temperature at which rocks form, which will allow scientists to better study the formation of Earth's crust and mantle as well as the formation of meteorites. Read Post
Geologists analyzed 40 meteorites that fell to Earth from Mars to understand the history of the Martian atmosphere. Their new article shows the atmospheres of Mars and Earth diverged in important ways early in the solar system's 4.6... Read Post
Much like on Earth's surface, water and rock reside deep within its crust, and they date to the earliest parts of the planet's history—leaving researchers fascinated by the secrets they may hold. In a new study published in Nature, ... Read Post
