New clues to the early Solar System from ancient meteorites

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.

Mars: Meteorites yield clues to Red Planet's early atmosphere

Academics / General Science : Science Daily (3 months ago)

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

New 'thermometer' helps scientists accurately measure rock formation

Academics / General Science : Science Daily (3 years ago)

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

Ancient Earth crust stored in deep mantle

Academics / General Science : Science Daily (last year)

Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth's crust. But decisive evidence for this phenomenon has proven elusive. New research now demonstrates that oceanic... Read Post
