Diamonds reveal deep source of platinum deposits The world's richest source of platinum and related metals is an enigmatic geological structure in South Africa known as the Bushveld Complex. This complex of ancient magmas is known to have formed some two billion years ago, but the source of its metallic riches has been a matter of scientific dispute.

Report confirms drilling, not earthquake, caused Java mud volcano A two-year old mud volcano which is still spewing huge volumes of mud, has displaced more than 30,000 people and caused millions of dollars worth of damage was caused by the drilling of a gas exploration well, an international team of scientists has concluded.

Data show Antarctic ice stream radiating seismically A seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial.

Large methane release could cause abrupt climate change An abrupt release of methane, a powerful greenhouse gas, about 635 million years ago from ice sheets that then extended to Earth’s low latitudes caused a dramatic shift in climate, triggering a series of events that resulted in global warming and effectively ended the last “snowball” ice age, a UC Riverside-led study reports.

Big quakes spark jolts worldwide Until 1992, when California’s magnitude-7.3 Landers earthquake set off small jolts as far away as Yellowstone National Park, scientists did not believe large earthquakes sparked smaller tremors at distant locations. Now, a definitive study shows large earthquakes routinely trigger smaller jolts worldwide, including on the opposite side of the planet and in areas not prone to quakes.

Scientists identified earthquake faults in Sichuan, China Only last summer research published by earth scientists in the international journal Tectonics concluded that geological faults in the Sichuan Basin, China “are sufficiently long to sustain a strong ground-shaking earthquake, making them potentially serious sources of regional seismic hazard."

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.

A Slow Birth for the Sahara An analysis of fine sediments at the bottom of an African lake has challenged the idea that the once-tropical-savanna-covered Sahara rapidly dried into what is now the largest desert on Earth. A report in tomorrow's issue of Science argues that the shift was gradual, taking place over 3000 years.

65-million-year-old asteroid impact triggered a global hail of carbon beads The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet, say scientists from the U.S., U.K., Italy, and New Zealand in this month's Geology.

Before fossil fuels, Earth's minerals kept CO2 in check Over millions of years carbon dioxide levels in the atmosphere have been moderated by a finely-tuned natural feedback system— a system that human emissions have recently overwhelmed.
'New' ancient Antarctic sediment reveals climate change history Recent additions to the premier collection of Southern Ocean sediment cores at Florida State University’s Antarctic Marine Geology Research Facility will give international scientists a close-up look at fluctuations that occurred in Antarctica’s ice sheet and marine and terrestrial life as the climate cooled considerably between 20 and 14 million years ago.
Earthquake in Illinois was from a new kid on the block To the surprise of many, the earthquake on April 18, 2008, about 120 miles east of St. Louis, originated in the Wabash Valley Fault, not the better-known and more-dreaded New Madrid Fault in Missouri’s bootheel.
Refining the date of the K/T boundary and the dinosaur extinction Scientists at the University of California, Berkeley, and the Berkeley Geochronology Center have pinpointed the date of the dinosaurs' extinction more precisely than ever thanks to refinements to a common technique for dating rocks and fossils.
