The quantitative model used in the study explains the enigmatic melt degrees and layered structures observed in most cratons on Earth. Monash University geologists have shed new light on the early history of the Earth through their discovery that continents were weak and prone to destruction in their infancy. Their […]

Kevin Gardner, an earth sciences doctoral student at the University of Oregon, stands in a riverbed in the Palo Verde Mountains, about nine miles southeast of Palo Verde, California. Behind him is Meaghan Emery-Wetherell, who earned a doctorate from the UO in 2016. The riverbed, within the Bouse Formation, contains […]

The fluid inclusions inside the olivine contain nanodiamonds, apart from serpentine, magnetite, metallic silicon, and pure methane. Credit: University of Barcelona Natural diamonds can form through low pressure and temperature geological processes on Earth, as stated in an article published in the journal Geochemical Perspectives Letters. The now found mechanism, far […]

ANIMATION Geoscientists have long known that some parts of the continents formed in the Earth’s deep past, but the speed in which land rose above global seas — and the exact shapes that land masses formed — have so far eluded experts. But now, through analyzing roughly 600,000 mineral analyses […]

A new study helps explain how and why columns of methane gas can stream out of seafloor formations known as methane hydrates. Credit: Image courtesy of the NOAA Office of Ocean Exploration and Research, Gulf of Mexico 2017. Leakage from frozen layers was a puzzle, but a new study shows […]

August 16, 2020. (Click here for high-resolution view.) Within an expanse of boreal forest in northwestern Alaska, two treeless stretches of sand stand out—the Great Kobuk Sand Dunes. With crests that rise as high as 100 feet (30 meters) above the surrounding forests, the dunes look like they belong in […]

Here on Earth, geologists seek out deep channels into Earth’s rock, carved over the ages by flowing water. The exposed rock walls are like a visual timeline of a region’s geological history. On Mars, the surface water is long gone. But it flowed long enough to expose layers of rock […]

Almond trees are at full bloom in late February. Most almond fields have two or more varieties within the field and require cross pollination by bees.
