Latest Crust Stories
New research from Matthew Jackson and Richard Carlson proposes that the remnants of six of the largest volcanic events of the past 250 million years contain traces of the ancient Earth's primitive mantleâ€”which existed before the largely differentiated mantle of todayâ€”offering clues to the geochemical history of the planet.
Ancient minerals tell story of planet's distant past.
Jewelers abhor diamond impurities, but they are a bonanza for scientists.
What would we see and what would we learn if we were able to cut North America in half, pull it apart, and look at the resulting cross section through the continent, from the surface all the way down to its very deepest mantle roots?
The inner core of the Earth is simultaneously melting and freezing due to circulation of heat in the overlying rocky mantle, according to new research from the University of Leeds, UC San Diego and the Indian Institute of Technology.
A team of scientists led by Rice University has figured out why the Colorado Plateau â€“ a 130,000-square-mile region that straddles Colorado, Utah, Arizona and New Mexico -- is rising even while parts of its lower crust appear to be falling.
For many years, most scientists studying Tibet have thought that a very hot and very weak lower and middle crust underlies its plateau, flowing like a fluid.
Geologists have long-debated about when plate tectonics started on the planet.
Researchers are hoping to attempt to drill into the Earth's mantle layer off the coast of Costa Rica in hopes of finding pristine samples of the earth's inner boundary.
Early in the formation of the Earth, some forms of the element chromium separated and disappeared deep into the planet's core, a new study by UC Davis geologists shows.
Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
