New technique suggests Medieval Warm Period made it to Antarctica
Scientists have developed a new method of reconstructing past climates that uses the water locked inside crystals in seabed sediment to shed light on the history of the Antarctic.
Why Iceland formed so differently from the gentle early Earth
How do you take the temperature of the Earth billions of years ago? The answer lies in the rocks.
Crystals in Picabo's rocks point to 'recycled' super-volcanic magma chambers
A thorough examination of tiny crystals of zircon, a mineral found in rhyolites, an igneous rock, from the Snake River Plain has solidified evidence for a new way of looking at the life cycle of super-volcanic ...
New trigger for volcanic eruptions discovered using jelly and lasers
Scientists have made an important step towards understanding how volcanic eruptions happen, after identifying a previously unrecognised potential trigger.
India joined with Asia 10 million years later than previously thought
The peaks of the Himalayas are a modern remnant of massive tectonic forces that fused India with Asia tens of millions of years ago. Previous estimates have suggested this collision occurred about 50 million ...
Early Earth less hellish than previously thought
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates.
Research update: Atomic motions help determine temperatures inside Earth
(Phys.org)—In December 2011, Caltech mineral-physics expert Jennifer Jackson reported that she and a team of researchers had used diamond-anvil cells to compress tiny samples of iron—the main element of the e ...
Mercury may have harbored an ancient magma ocean, paper reveals
By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's ...
Evolution stuck in slime for a billion years
Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits.
Earthquakes and tectonics in Pamir Tien Shan
Real time analysis of shear waves as a means of earth quake hazard mitigation. First time observed continental subduction in a continent-continent collision.
Seashells provide million-year-old weather report
New research, published in Earth and Planetary Research Letters, led by scientists from the University of Cambridge, used plankton – tiny bugs, whose shells litter the ocean floors. By drilling into the ...
Greenland's current loss of ice mass
The Greenland ice sheet continues to lose mass and thus contributes at about 0.7 millimeters per year to the currently observed sea level change of about 3 mm per year. This trend increases each year by a further 0.07 millimeters ...
Meteorite samples provide definitive evidence of water and rock types on Mars
Researchers at the Tokyo Institute of Technology, NASA's Johnson Space Center, Lunar Planetary Institute, and Carnegie Institute of Washington report on geochemical studies that help towards settling the ...
Extinct undersea volcanoes squashed under Earth's crust cause tsunami earthquakes
New research has revealed the causes and warning signs of rare tsunami earthquakes, which may lead to improved detection measures.
