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 eruptions in ...
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 years ago, as ...
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 earth's core. ...
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 surface, scientists ...
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.
