Latest Crust Stories
An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved.
As tags on household appliances warn, water conducts electricity extremely well. Now, scientists have found that enhanced electrical conductivity in parts of Earth's mantle may signal the presence of water far below our planet's surface.
The research is reported in a Nature paper titled â€œProgressive mixing of meteoritic veneer into the early Earthâ€™s deep mantleâ€.
Venus Express has charted the first map of Venus's southern hemisphere at infrared wavelengths.
The Earth's mantle, situated under the Earth's crust, is very much the spot for studying interesting geological processes. Although we do not realise it, right under our feet there is a sultry world of circulating Earth layers.
For the first time scientists have discovered the presence of a natural deep earth pump that is a crucial element in the formation of ore deposits and earthquakes.
By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth.
For decades, geologists have been puzzled by the mechanisms that give rise to the kind of volcanoes that form the so-called â€œring of fireâ€ around the Pacific Ocean.
California Raisin Category Winners Announced at the American Pie Council's Crisco National Pie Championships FRESNO, Calif., June 1 /PRNewswire/ -- The California Raisin Marketing Board (CRMB) is proud to announce the winners of the second annual California Raisin category in the amateur division at the 2009 Crisco(R) National Pie Championships, hosted by the American Pie Council (APC) last month in Celebration, Florida.
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation.
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)....
