Today, China controls the vast majority of rare earths processing. That gives it enormous political leverage, and its trade truce with the US involving those minerals expires Nov. 10, 2026.
It might appear featureless, but one of the world’s largest limestone regions hides a remarkable underground world.
The amount of undeclared uranium from the DRC’s cobalt mines could – if processed – produce enough material for 600-1,500 nuclear weapons.
Africa has some of the world’s most important geological landscapes, yet they remain under-represented in digital geoheritage research.
New research argues no other concept reflects our planet-wide transformation in its proper context of deep time.
A geologist explains how thawing permafrost and melting ice are increasing the risk of destructive floods in the Himalayas and other high mountain regions around the world.
The tracks are the first to be found in Canada from this time period.
A fish-finding expedition not only detects unexpected species but also uncovers a living link to Missouri’s geological past.
Understanding what happened in these forests 56 million years ago may help humanity recognize similar thresholds before we cross them again, the lead author of a new study writes.
Nearly four centuries after the Batavia wrecked, a new study about its precious cargo shows that stories can indeed be written in stone.
Studying the mineral olivine in kimberlite sheds some light on diamond origins.
Today, plate tectonics carry water into Earth’s depths. But this deep water cycle goes back much further.
New solutions to two interlinked mysteries reveal how and why the Antarctic’s enormous ice sheet formed.
Why it’s still difficult to accurately predict earthquakes.
Both faults are along plate boundaries that move in similar ways and have ruptured in enormously destructive earthquakes in the past.
Battered by asteroid impacts, the young Earth was hot and unstable for hundreds of millions of years.
The two deadly earthquakes happened just 39 seconds apart, but were seismologically distinct.
The oldest known impact structure on Earth has been confirmed in outback Australia.
This is the first evidence that the mineral garnet may have been formed within the crust of Mars itself, heralding clues to the planet’s complex history.
