Researchers Found an Abundance of Helium In Canada’s Baffin Island


    Long-time Slashdot reader thepacketmaster writes: Documented in a recent article in the journal Nature, researchers have found an abundance of both helium-4 and helium-3 trapped in the volcanic rocks on Canada’s Baffin Island. As the Earth formed, it is thought that helium-4 and helium-3 flowing on the solar wind became trapped in the minerals of the cooling planet. With heavier elements and minerals sinking to the bottom, this trapped helium was transported to the core, where it would have remained locked in its original forms. Earth isn’t massive enough to hold on to helium in any significant quantities, though. Any that did not get trapped, or that was subsequently released when the minerals melted in the mantle or due to massive impacts, would have eventually seeped up to the surface and floated off into space. So, helium is relatively rare on Earth, and helium-3 is even more so. Read more of this story at Slashdot.
