They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...
Stretching 4,000 miles, the East African Rift System is one of the largest in the world—and scientists just uncovered the hidden force tearing it apart.
Now, in a new study, scientists at the University of Glasgow—armed with data gathered at the Menengai geothermal field in Kenya—analyzed of the noble gas neon and determined that it originates ...
Luckily, by analyzing noble gases from the Kenyan geothermal field, scientists found that contamination was minimal. Additionally, they discovered that those same neon isotopic features had also been ...
Gas samples from wells and springs are situated along mixing lines between mantle and CO 2. Credit: Geophysical Research Letters (2025). DOI: 10.1029/2025GL115169 ...
Since the rocks tell us about gas proportions in the early Solar System, it tells us that the amount of xenon in our current atmosphere is around 10 percent of what we'd expect it to be.
They wanted to investigate the rocks that may contain insights about the contents locked within Earth’s core and mantle, the mostly solid layer of Earth’s interior located beneath its surface.
Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. As helium-3 leaked from the core, it ascended to the ...

(CNN) — Scientists have detected a surprising amount of a rare version of helium, called helium-3, in volcanic rocks on Canada’s Baffin Island, lending support to the theory that the noble gas ...
