While helium-4 is common on Earth, helium-3 is more readily found elsewhere in the cosmos, which is why scientists were surprised to detect a larger amount of the element than had been previously reported from the rocks on Baffin Island. A study describing the discovery
The composition of a planet is a reflection of the elements that formed it, and previous research found that trace amounts of helium-3 leaking from Earth’s core supports the popular theory that our planet originated in a solar nebula — a cloud of gas and dust that likely collapsed due to the shock wave of a nearby supernova — which contained the element.
“Many of the lavas are full of bright green olivine , so breaking off fresh pieces with a rock hammer was as thrilling as breaking apart geodes as a kid: each rock was a treasure to be discovered,” Horton said. “And what scientific treasures they turned out to be!” 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 surface through the mantle in the form of magma plumes that eventually erupted on Baffin Island.
Helium leaking from Earth’s core doesn’t affect our planet or have any negative implications, he said. The noble gas does not chemically react with matter, so it won’t have an impact on humanity or the environment.
