Opening Atlantic Leaves Scots Isle Platinum Rich
The Platinum Group Elements (PGEs) are contained in mineral grains from the Rum Layered Intrusion, which represents the eroded roots of a once large volcano. They were formed deep in the crust as a plume of molten rock pushed up from deep within the Earth, causing huge volcanic eruptions, as well... view more (1999-02-08)

Scientists explore huge volume of molten rock now frozen into the crust under the ocean's floor
For the first time scientists have mapped the layers of once molten rock that lie beneath the edges of the Atlantic Ocean and measure over eight miles thick in some locations.   view more (2008-03-28)

UBC study may solve age-old mystery of missing chemicals from Earth's mantle
Observations about the early formation of Earth may answer an age-old question about why the planet's mantle is missing some of the matter that should be present, according to UBC geophysicist John Hernlund.   view more (2007-12-06)

Key component of Earth's crust formed from moving molten rock
Earth scientists are in the business of backing into history -- extrapolating what happened millions of years ago based on what they can observe now. Using this method, a team of Cornell researchers has created a mathematical computer model of the formation of granulite, a fine-grained metamorphic... view more (2008-03-06)

Arizona State University geophysicists detect a molten rock layer deep below the American Southwest
A sheet of molten rock roughly 10 miles thick spreads underneath much of the American Southwest, some 250 miles below Tucson, Ariz. From the surface, you can't see it, smell it or feel it.   view more (2007-06-21)

Yellowstone's Ancient Supervolcano: Only Lukewarm?
The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found.   view more (2008-08-28)

Looking deep in Earth, researchers see upwellings that could be root of volcanic islands
Deep within Earth, researchers are finding hints of exotic materials and behaviors unrivaled anywhere else on the planet. Now a team of researchers is making connections between the dynamic activities deep inside Earth and geologic features at its surface.   view more (2005-06-01)

MIT forges greener path to iron production
MIT engineers have demonstrated an eco-friendly way to make iron that eliminates the greenhouse gases usually associated with its production.   view more (2006-09-13)

Earth-shattering proof of continents on the move
AFRICA is being torn apart. And as Ethiopia's rift valley grows slowly wider, an international team of scientists is taking a unique opportunity to plot the progress of continents on the move.   view more (2007-01-30)

Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean.   view more (2007-04-13)

Environmentally friendly drilling with computers
A new doctoral dissertation from Lule'å University of Technology in Sweden deals with processes, systems, and problems in the use of a newly developed, environmentally friendly rock drilling method. The method, which is patented for the entire world, uses only water both to run the drill and... view more (2004-12-20)

Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor.   view more (2006-07-31)

Fragmented Structure of Seafloor Faults May Dampen Effects of Earthquakes
Many earthquakes in the deep ocean are much smaller in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution (WHOI) have found new evidence that the fragmented structure of seafloor faults, along with previously unrecognized volcanic activity, may be dampening the... view more (2007-07-13)

3.2 Billion-Year-Old Surprise: Earth Had Strong Magnetic Field
Geophysicists at the University of Rochester announce in today's issue of Nature that the Earth's magnetic field was nearly as strong 3.2 billion years ago as it is today.   view more (2007-04-05)

Predicting Volcanic Eruptions
The weather forecast could help predict volcanic eruptions, according to new research from the University of East Anglia (UEA). Scientists from UEA`s School of Environmental Sciences found that intense rainfall can trigger volcanic dome collapse - a particular type of eruption that occurs when a... view more (2002-09-04)

Mysterious rock markings discovery baffles archaeologists
THE discovery of a series of mysterious rock carvings has sparked a quest among experts to find out exactly what they are. Archaeologists from the University of Newcastle upon Tyne, who were alerted to the carvings by a local farm-hand, are baffled as to what they mean or who created them. Fellow... view more (2003-10-09)

Yellowstone's quiet power
A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering.   view more (2007-03-01)

Rock 'Face' Mystery Baffles Experts
Archaeologists have found a trio of extraordinary stone carvings while charting the phenomenon of prehistoric rock markings in Northumberland, close to the Scottish border in the United Kingdom. Records and examples of over 950 prehistoric rock art panels exist in Northumberland, which are of the... view more (2004-06-17)

A Fresh Look Inside Mount St. Helens
Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don't know.   view more (2008-02-20)

Discovery sheds new light on cause of earthquakes
Research at the University of Liverpool into a large fault zone in the Atacama Desert in northern Chile has produced new insight into how fluid pressure can cause earthquakes.   view more (2006-12-14)

Built on sand
Numerical modelling of geological deformation processes Innsbruck/Vienna (FWF) - The precise knowledge of geological stresses, faults, fissures or folds is essential for tunnelling projects, earthquake forecasts or the final storage of radioactive waste. Sponsored by the Austrian Science Fund... view more (2001-04-23)

Risk, anger and beauty in the eye of the beholder
Risk taking rock climbers, people who worry and perception of beauty in others are some of the topics covered in more than 40 poster presentations of research being presented at the British Psychological Society's Annual Conference at the University of Manchester today, Thursday 31 March 2005.   view more (2005-03-21)

Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple... view more (2008-08-20)

Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria.   view more (2006-03-24)

Radioactive crystals help identify and date ore deposits
Reddish-brown crystals of a radioactive mineral called monazite can act as microscopic clocks that allow geologists to date rock formations that have been altered by the action of high-temperature fluids, a process that frequently leads to the formation of rich ore deposits.   view more (2006-08-01)
