Earth's crust melts easier than thought
Earth's crust melts easier than previously thought, scientists have discovered. In a paper published in this week's issue of the journal Nature, geologists report results of a study of how well rocks conduct heat at different temperatures. They found that as rocks get hotter in Earth's crust, they become better insulators and poorer conductors. view more (2009-03-19)
Seismologists detect a sunken slab of ocean floor deep in the Earth
Halfway to the center of the Earth, at the boundary between the core and the mantle, lies a massive folded slab of rock that once formed the ocean floor and sank beneath North America some 50 million years ago. view more (2006-05-18)
Star crust 10 billion times stronger than steel, IU physicist finds
Research by a theoretical physicist at Indiana University shows that the crusts of neutron stars are 10 billion times stronger than steel or any other of the earth's strongest metal alloys. view more (2009-05-07)
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 effects of these quakes. view more (2007-07-13)
Deep subsurface research to help understand earthquakes
From 8 to 20 October, TU Delft, "Vrije Universiteit Amsterdam" and The University of Utrecht will be conducting an experiment in the south of the Netherlands. The experiment is to find out how the deep subsurface (about 25 to 30 km under the surface) can be profiled with sound waves. It is the first time that Dutch subsurface will be... view more...

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 as hastening the break-up of North America from... view more...

Magnetic Storms And Earthquakes
For years scientists have been studying the impact of different geophysical fields on the earthquakes occurrence. It has been assumed that the fields, generated due to the solar activity, earth flows fluctuations, the Earth`s speed of rotation and even the launch of magnetohydrodynamic generators affect the strained state of the earth`s crust,... view more...

Scientists aim to unlock deep-sea 'secrets' of Earth's crust
Scientists from Durham University will use robots to explore the depths of the Atlantic Ocean to study the growth of underwater volcanoes that build the Earth's crust. view more (2008-05-14)
Argon conclusion: Researchers reassess theories on formation of Earth's atmosphere
Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of the journal Nature, could change the way scientists view the formation of Earth's atmosphere and those of our distant neighbors, Mars and Venus. view more (2007-09-20)
Hydrocarbons in the deep Earth?
The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. view more (2009-07-27)
Hot climate could shut down plate tectonics
A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place. view more (2008-05-13)
Technique measures heat transport in the Earth's crust
Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet. view more (2009-03-31)
GPS technology aids earthquake research
Scientists' understanding of the movement of the Earth's crust is being helped by new observing facility which is taking measurements that may one day help predict earthquakes. Newcastle University's School of Civil Engineering and Geosciences has become only one of two UK centres feeding Global Positioning System (GPS) data into the International... view more...

Continents loss to oceans boosts staying power
New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. view more (2008-04-02)
The Baikal Basin Is Extending
For millions of years Lake Baikal has remained a deep-water repository of relic fauna and pure fresh water, although its basin is constantly being filled up with the alluvion brought by violent landslides, slide-rocks, mudflows and rapid tributaries. Obviously, to keep the balance the basin should extend at least by the volume of delivered... view more... (2002-05-17)
Oldest Known Rock on Earth Discovered
Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust. view more (2008-09-29)
Seismic response to natural gas anomalies in crystalline rocks
The research done at the Chinese Academy of Geological Sciences has shown that after geochemical experiments, the porosity of crystalline rocks in the middle crust increases sharply due to water-rock interaction. view more (2008-11-05)
Natural deep earth pump fuels earthquakes and ore
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. view more (2009-06-18)
