Some of the world’s oldest rubies linked to early life

While analyzing some of the world's oldest coloured gemstones, researchers from the University of Waterloo discovered carbon residue that was once ancient life, encased...

Earth’s ‘solid’ inner core may contain both mushy and hard iron

3,200 miles beneath Earth's surface lies the inner core, a ball-shaped mass of mostly iron that is responsible for Earth's magnetic field. In the...

Geologists dig into Grand Canyon’s mysterious gap in time

A new study led by the University of Colorado Boulder reveals the complex history behind one of the Grand Canyon's most well-known geologic features:...

Geologists take Earth’s inner temperature using erupted sea glass

If the Earth's oceans were drained completely, they would reveal a massive chain of undersea volcanoes snaking around the planet. This sprawling ocean ridge...

Earth’s climate life story, 3 billion years in the making

One of Earth's greatest mysteries is how it transformed itself, ever so gradually, from a barren ball of rock into a launching pad for...

A rock with many perspectives

The Alum Shale of Northern Europe not only has an eventful history of formation, connected with the microcontinent Baltica, it also holds great potential...

The Earth has a pulse — a 27.5-million-year cycle of geological...

Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a "pulse," according to a new study published in the journal...

Earth-like biospheres on other planets may be rare

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work...

Earth’s oldest minerals date onset of plate tectonics to 3.6 billion...

Scientists led by Michael Ackerson, a research geologist at the Smithsonian's National Museum of Natural History, provide new evidence that modern plate tectonics, a...

Clues from soured milk reveal how gold veins form

For decades scientists have been puzzled by the formation of rare hyper-enriched gold deposits in places like Ballarat in Australia, Serra Palada in Brazil,...

Where on Earth is all the water?

High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that...

Yellowstone National Park is hotter than ever

Yellowstone National Park is famous for harsh winters but a new study shows summers are also getting harsher, with August 2016 ranking as one...

A closer look at the creation of a metamorphic sole

When two of Earth's tectonic plates collide, the heavier plate is forced underneath and back into the mantle in a process called subduction. During...

A deep reservoir of primordial helium in the Earth

Noble gases, including helium, neon, and argon, are characterized by high chemical inertness which causes low reactivity with other materials and high volatility. Among...

Scientists probe mysterious melting of Earth’s crust in western North America

A group of University of Wyoming professors and students has identified an unusual belt of igneous rocks that stretches for over 2,000 miles from...

Earth’s crust mineralogy drives hotspots for intraterrestrial life

Below the verdant surface and organic rich soil, life extends kilometers into Earth's deep rocky crust. The continental deep subsurface is likely one of...

Traces of Earth’s early magma ocean identified in Greenland rocks

New research led by the University of Cambridge has found rare evidence -- preserved in the chemistry of ancient rocks from Greenland -- which...
