Nature Communications, Published online: 08 September 2026; doi:10.1038/s41467-026-77506-z Using magnetic records preserved in plagioclase of 260-million-year-old gabbro, the study finds that Earth’s magnetic field abruptly declined to half today’s strength but remained too strong to deplete ozone or drive Late Permian extinctions.

Layers of sedimentary rock that jut from the Soledad Basin at surprising angles have long enthralled television and film producers, including the team behind Star Trek. The post The Otherworldly Geology of Vasquez Rocks appeared first on NASA Science .

After the deadly Grand Canyon flood, a geologist and avid hiker explains what nature lovers need to prepare and watch for to stay safe.

Our new ELI today involves planning some careful fieldwork using, as an example, the Burbage Valley in the Peak District, UK - 'Burbage Valley Part 1 - An ancient river system; using field measurements to determine the origins of a sandstone sequence'.

Scientific Reports, Published online: 07 September 2026; doi:10.1038/s41598-026-65339-1 Fossil pockmark-related carbonate deposition reveals late Miocene fluid migration in the Majella petroleum system (Central Italy)

On Baffin Island, a wall of ancient granite leans 15 degrees past vertical for 1,250 metres, producing the longest uninterrupted freefall path on any cliff on Earth.

Beneath the red dust of remote Queensland, ancient groundwater carries the smell of deep time—and reveals surprising secrets about survival in the arid interior.

Nature Sustainability, Published online: 24 August 2026; doi:10.1038/s41893-026-01918-4 Millions of people are impacted by land subsidence, which is accelerated by human-induced drivers. Across Europe, research and policy is focused on managing these drivers and mitigating their influence, with data and monitoring infrastructure playing a key role in tackling future challenges.

Scientists have to follow the data, even if it doesn't make sense. This is the...

Earth’s inner core remains one of the planet’s hardest places to understand. Now, an extreme laboratory experiment has uncovered unusual behavior that researchers had struggled to observe directly.

The magnetic North Pole has shifted over the millennia, leaving clues in the minerals that make up clay antiquities

A new study from Caltech shows that Mars' southern hemisphere is much hotter than expected deep below the surface. Why is that? The post Mars’ southern hemisphere is unusually hot deep underground first appeared on EarthSky .

Copper-gold explorer and hybrid prospect generator Kincora Copper Limited (Kincora) is pleased to provide an update on planned sole funded exploration over the upcoming Spring and Summer field season including over 25,000 meters of air-core drilling across four projects in Central West NSW, Australia.

The Chicxulub impact and the multifractal organization of geological time provide two empirical anchors for TCGS--SEQUENTION by independently fixing the framework's source--projection--Shadow discipline. Here an empirical anchor is an externally measured, reproducible structure that stabilizes an operational distinction and constrains admissible source-to-readout maps; it is not a stand-alone der…

Geologists recently identified a 454.4 million-year-old volcano on England's east coast, but whether the structure can be considered a "supervolcano" remains an open question.

IntroductionInterlayer slip is a key mechanism during fold evolution; however, its effects on preexisting or contemporaneous secondary structures (e.g., cleavage and fractures) remain poorly constrained. This study investigates a well-exposed outcrop in the southern Yidun Arc, northwestern Yunnan, to decipher the modification of fold-related structures by interlayer slip and the resulting tectoni…

The Gakkel Ridge is the slowest spreading mid ocean ridge on Earth, and the new reading suggests its melt reaches the surface in bursts rather than in a continuous supply.

Star Wars is one of the most influential science-fiction worlds created in our time. The central theme revolves around the struggle between the tyrannical Galactic Empire and the rebels trying to bring it down. Star Wars has many reasons to pull you in: iconic lightsaber duels, technological advancements such as hyperspace travel, and perhaps most importantly for a geologist: a remarkable number …

Researchers trained an AI model to identify signals in the Earth’s core-mantle boundary that could be harbingers of tectonic activity.
