Is there an ocean beneath our feet?

An arc volcano in Chile Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth’s oceans to the upper mantle than previously thought. Water is carried mantle by de...

Megafloods: What They Leave Behind

Stubby Canyon, Malad Gorge State Park, Idaho. (Credit: Michael Lamb)South-central Idaho and the surface of Mars have an interesting geological feature in common: amphitheater-headed canyons. These U-shaped canyons with tall vertical headwalls are f...

Granite research revises heat under Perth's surface

“The high radiogenic heat generation in the Darling Range appears to be the cause of the hot water within the Perth Basin, as the granites of the Darling Range extend under the Perth Basin, which provides the sedimentary blanket," Dr Middle...

Scientists Discover Quick Recipe for Producing Hydrogen

Nature produces hydrogen through "serpentinization." When water meets the ubiquitous mineral olivine under pressure, the rock absorbs mostly oxygen (O) atoms from H2O, transforming olivine into another mineral, serpentine -- characterize...

Pre-Industrial Rise in Greenhouse Gases Had Natural and Anthropogenic Causes

For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere - from about 5,000 years ago to the start of the industrial revolution - were triggered by natural causes or human activities.

Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago

Credit: NASA RIVERSIDE, Calif. — Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events — typically marked by signi...
