Latest Mantle Stories
Earth today is one of the most active planets in the Solar System, and was probably even more so during the early stages of its life.
Using a diamond-anvil cell to recreate the high pressures deep within the earth, researchers at the California Institute of Technology (Caltech) have found unusual properties in an iron-rich magnesium- and iron-oxide mineral that may explain the existence of several ultra-low velocity zones (ULVZs) at the coreâ€“mantle boundary.
New seismic technique detects boundary between old and new lithosphere.
While prospectors and geologists have been successful in finding diamonds through diligent searching, one University of Houston professor and his team's work could help improve the odds by focusing future searches in particular areas.
The Moonâ€™s geological past could be better understood by a mineral that Japanese astronomers report they have found.
Scientists have used quantum mechanics to reveal that the most common mineral on Earth is relatively uncommon deep within the planet.
SAN DIEGO, March 23 /PRNewswire/ -- For decades, an unsuspected geological blunder has limited crucial technical understanding of how, where and why petroleum and natural gas deposits form.
Clues point to 'density trap' in early mantle.
A new study in the journal Geophysical Research Letters has confirmed previous theoretical predictions that the churning cauldron of molten metals that make up Earth's liquid outer core is slowly being stirred by a very complex but predictable series of periodic oscillations.
Earth scientists at Brown University have found strong evidence that the geological processes that lead to the formation of oceanic crust are not as uniformly passive as believed.
Leptopecten latiauratus, the common name being the kelp scallop, is a small saltwater clam, a bivalve mollusk belonging to the family Pectinidae. It resides in water up to 850 feet deep. Similar to other scallops, it has many small primitive eyes around the rim of its mantle and escapes its predators by jet propulsion. The shell can be anywhere between 3 to 5 centimeters in size. It is mostly circular with two flat auricles or ears that extend off of the hinge. It usually has ridges that...
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)....
