Geology

It's the first time Earth's geologic record — information found inside rocks — has been used to create an animation of this kind.

A helium reservoir with the highest concentrations ever seen could hold enough of the gas to address critical shortages in the U.S. affecting tech, medicine and space exploration.

Geologists have known for decades that gold forms in quartz with the help of earthquakes, but now they have worked out exactly how the setting and seismic waves combine to form large nuggets.

Al Naslaa is a rock formation in Saudi Arabia's northwestern desert consisting of two huge, symmetrical stone blocks that are separated by a mysterious gap and sit on small pedestals.

In Racetrack Playa, a dry lakebed in Death Valley National Park, meteorological conditions can push rocks weighing up to 700 pounds along the flat ground.

Structures that scatter seismic waves deep in Earth's mantle seem to be everywhere researchers look.

Geological evidence of the transition when Earth was plunged into a planetary-wide deep-freeze discovered in ancient Scottish rocks.

The Yarlung Tsangpo Grand Canyon is Earth's largest terrestrial canyon, stretching 314 miles long and almost 20,000 feet from top to bottom at its deepest point in the Tibet Autonomous Region.

Scientists just pulled the longest hunk of Earth's mantle from beneath the ocean.

Dramatic cliffs and high plateaus are caused by the same wave triggered in Earth's middle layer when continents pull apart, a new study finds.
