New orbital data reveal that the most recently active volcanic systems on Mars weren’t simple one-off blasts into space; instead, long-lived magmatic...

Two immense, ultrahot rock structures located at the base of Earth’s mantle, around 2,900 km beneath Africa and the Pacific, have been shaping Earth’s...

A team of geologists from China and Australia has found evidence that episodic eruptions from vast marine large igneous provinces (LIPs) drove repeated...

Researchers have found ancient gases and fluids trapped in 1.4-billion-year-old halite crystals from northern Ontario, Canada. Their analyses directly...

For decades, scientists have been baffled by two enormous structures buried deep inside Earth. These anomalies may retain geochemical signatures distinct...

Researchers have discovered an impact crater formed on a granite mountain capped by a thick weathering crust in southern China. Located in Zhaoqing in...

Researchers have discovered 6-million-year-old-ice and air in shallow ice cores drilled in the Allan Hills region of East Antarctica. They speculate that...

The newly-discovered mineral, named ferric hydroxysulfate, provides clues about the environment and history of the Red Planet, including the possibility...

Tektites are nearly pure glasses (practically no crystalline inclusions) created when a space rock slams into Earth, melting surface material and hurling...

Submarine canyons are deep, large-scale incisions found on most of the world’s continental margins. In Antarctica, they are widespread features driving...

The Martian meteorite Northwest Africa (NWA) 16254 is a 406-g gabbroic shergottite found two years ago in Algeria. Image of the entire NWA 16254 sample...

Geologists have discovered compelling evidence for preservation of Hadean rocks — dating back to 4.16 billion years old — in a complex geological...

Paleontologists have analyzed the body profiles of Ediacaran-Cambrian organisms by using trace fossils as proxies for body fossils. A reconstruction of...

Locally known as Maka Lahi, meaning ‘Big Rock,’ this boulder was moved more than 200 m inland by a tsunami around 7,000 years ago. The limestone boulder...

Planetary scientists expected the outermost layer of the crust of Earth’s hotter twin would grow thicker and thicker over time given its apparent lack...

Previously believed to have occurred 1.2 billion years ago, this ancient impact created the Stac Fada Member, a layer of rock that holds vital clues to...
