Latest Crust Stories
The Moonâ€™s geological past could be better understood by a mineral that Japanese astronomers report they have found.
Geological investigations in the Himalayas have revealed evidence that when India and Asia collided some 90 million years ago, the continental crust of the Indian tectonic plate was forced down under the Asian plate, sinking down into the Earth's mantle to a depth of at least 200 km kilometers.
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.
When it comes to three-dimensional puzzles, Rubik's Cube pales in comparison with the latest creation of Rice University geoscientist Richard Gordon.
Clues point to 'density trap' in early mantle.
FRESNO, Calif., Jan.
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.
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton.
The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago.
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)....
