Crystal gems found in extreme igneous rocks could form within hours, study suggests
Researchers from Rice University in Texas and the University of California, Riverside have found that gems can grow within hours inside extreme igneous rocks called pegmatites, instead of the thousands of years they usually take to form. In a study published in the journal Nature, the researchers described how they examined sample crystals from a pegmatite mine in Southern California. Using […]

Study: Benign volcanoes may be more explosive than previously thought
A recent study published in the journal Nature Communications found that benign volcanoes that produce basaltic lava flows hide highly explosive magma components. Many volcanoes do not cause life-threatening eruptions even though they release a steady stream of lava. For example, volcanoes in Iceland, Hawaii and the Galapagos Islands consistently emit lava comprised of molten basaltic rock. […]

The Earth’s mantle is a “geochemically diverse mosaic,” reveals team of geologists
The typical visual depiction of the Earth’s mantle as a solid band of yellow-orange sitting between the crust and core has just received an update. A recent paper in Nature Geoscience now describes it as “more heterogenous” than what people previously thought. An international group led by the University of Utah provided a more diverse representation of the mantle, far different compared […]

Scientists thought they knew volcanoes – until they looked under Bermuda
The Bermuda Islands sit atop evidence of a new process of volcanic formation. Researchers have discovered that molten material from the Earth’s mantle transition zone might filter toward the surface and form a volcano. Experts know of two methods of volcanic formation. One of the processes takes place when tectonic plates crash together. The other process involves […]

“Tree kill zone” in Yellowstone National Park hints at new magma activity below the surface
The massive amounts of magma slumbering beneath Yellowstone National Park stir anew. Researchers reported the appearance of a new thermal area in the park that killed off the plants in its vicinity. The area measured eight acres (3.2 hectares), enough to fit four soccer fields. It first appeared on infrared images taken by Landsat satellites […]

New study overturns classic ideas about volcanic eruptions
When you were younger, you were probably taught that volcanoes contained a central chamber filled with molten material called magma. But a British study claims that that there is no such underground space inside a volcano, only many small pockets filled with crystals and magma. These findings are earthshaking in more ways than one. Our […]
