Krypton from the Earth’s mantle, collected from geologic hot spots in Iceland and the Galapagos Islands, reveals a clearer picture of how our planet formed, according to new research from the ...

Artist's impression of planets forming around a young star. New, very precise measurements of krypton isotopes from deep in the Earth show that water, carbon and other volatile materials were ...

PROVIDENCE, R.I. [Brown University] — The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't ...

Earth’s mantle is the thick layer of silicate rock between Earth’s crust and its molten core, making up about 84% of our planet’s volume. The mantle is predominantly solid but, on geologic time scales ...

A new study brings insight to how atmospheric noble gases, in particular argon and neon, cycle from the surface to the Earth's mantle, and back to the surface again. With every breath we take, we ...

A conundrum has long vexed geoscientists: How to reconcile convection of the Earth's mantle with observations of ancient noble gases in volcanic rocks. Solving the problem requires that the recycling ...

The evidence is in every breath of air, but answers are harder to come by. Xenon, the second heaviest of the chemically inert noble gases, has gone missing. Our atmosphere contains far less xenon, ...
