Measurements of helium isotopes in the ground waters and natural gases of sedimentary basins reveal that some possess a major component of mantle-derived helium, apparently related to their mechanism of formation. Neogene basins formed by loading do not involve introduction of significant mantle helium,...

Isotopes Main article:Isotopes of helium There are eight known isotopes of helium, but only helium-3 and helium-4 are stable. In the Earth's atmosphere, there is one 3He atom for every million 4He atoms.[4] Unlike most elements, helium's isotopic abundance varies greatly by origin, due ...
Natural helium consists of two stable isotopes: 3He and 4He (4He predominates by far). Helium was first discovered not on earth, where there is little of it, but in the sun’s atmosphere. In 1868 the Frenchman P. J. C. Janssen and the Englishman J. N. Lockyer studied the spectroscopi...
