Earth’s mantle may have been cooler than anyone thought before Pangea ripped apart
A study published in Earth and Planetary Science Letters challenges a widely held assumption about the thermal state of Earth ...
Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...
Teeming with heat-loving microbes, samples of fluid drawn from the crustal rocks that make up most of the Earth’s seafloor are providing the best evidence yet to support the controversial assertion ...
