Lengthy-time Slashdot reader thepacketmaster writes: Documented in a up to date article within the magazine Nature, researchers have discovered an abundance of each helium-4 and helium-3 trapped within the volcanic rocks on Canada’s Baffin Island.
Because the Earth shaped, it’s concept that helium-4 and helium-3 flowing at the sun wind become trapped within the minerals of the cooling planet. With heavier parts and minerals sinking to the ground, this trapped helium was once transported to the core, the place it might have remained locked in its authentic paperwork.
Earth is not huge sufficient to carry directly to helium in any vital amounts, regardless that. Any that didn’t get trapped, or that was once due to this fact launched when the minerals melted within the mantle or because of huge affects, would have in the end seeped as much as the outside and floated off into area. So, helium is fairly uncommon on Earth, and helium-3 is much more so.
