Deposition

Scientists have found previously undocumented ash deposits buried beneath the Lava Creek Tuff in Wyoming — and at least one of them could be from an unknown volcanic eruption, they say.

Analysis of the sediment in Belize's Great Blue Hole shows a concerning trend.

Fossils of 444 million-year-old creatures whose bodies were preserved "inside-out" have been discovered in South Africa.

PRETORIA, South Africa, Mar 21 (IPS) - World Water Day, celebrated on March 22 every year, raises awareness about the importance of water and advocates for the sustainable management of freshwater resources. The theme for 2025 focuses on glaciers — those grandiose ice masses that are a crucial part of the world's water resources.

By coring the seabed at 850 m water depth in Disko Bay off Greenland's west coast, researchers from the University of Copenhagen have obtained the first historical record of plastic pollution in Greenland. The new data suggest a link to local socio-economic development and represent a step towards developing a common method for analyzing and mapping global microplastic pollution.

Critical minerals are in demand around the world for military, technological and other uses. A geoscientist shares what's known about Ukraine's reserves, which could help the country recover from war

The flood may have refilled the entire Mediterranean Basin in just two years.

Paleontologists have discovered a new species of early gorgonopsian therapsid that was part of an ancient summer wet biome of equatorial Pangea.

Incredibly well preserved dinosaurs at China fossil site were thought to have been buried in huge volcanic eruptions, similar to the Mount Vesuvius that covered the city of Pompeii 2,000 years ago. But new research says this isn't how things happened.

New dating of a major ancient warming shows warming started before major eruptions.

How does an unreactive, barely soluble metal end up forming giant chunks?

Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil record has gaps and is incomplete, and we're missing data that we need to reconstruct evolutionary history.

Researchers uncovered matching sets of hundreds of dinosaur footprints in Africa and South America, revealing a dinosaur highway used 120 million years ago.

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

A newly discovered half-million-year-old layer of volcanic sediment beneath the Aegean Sea rewrites what scientists know about this area's volcanic history –...

Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals.

A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In wetter, forested areas, gaseous mercury from the air sticks to leaves, which then fall and carry the toxin into the ground.

Water that's too hard or too soft could damage pipes and lead to health and aesthetic concerns. Whether you have hard or soft water, don't worry too much. Water treatment plants take appropriate measures to ensure safe water for the communities they support.
