The special position of helium among the elements has been recognized since the early days of radium. Like all the other noble gases (except the radiogenic Am), the maximum estimated abundance of helium in the atmosphere and the rocks of the earth's crust falls far below any estimate of its cosmic abundance. The theories of earth formation, which become increasingly credible in their modern versions, agree in ascribing this loss of helium' t o its inability to form solid or liquid phases or… Expand
The Origin of Methane (and Oil) in the Crust of the Earth
The deposits of hydrocarbons in the crust of the Earth have long been regarded by many investigators as deriving from materials incorporated in the mantle at the time of the Earth's formation.Expand
Helium Loss, Tectonics, and the Terrestrial Heat Budget
TLDR
It is now clear that somewhat contrary to expectation, substantial degassing is also taking place through the continental crust and in western Europe the escape of mantle volatiles seems to occur largely where the crust is undergoing active extension. Expand
Helium isotopes in the earth's interior and in the atmosphere: A degassing model of the earth
Abstract A first-order degassing model was applied to describe the evolution of helium content and isotope composition in the earth and in the atmosphere. The main events described by the model are:Expand
Origin of Noble Gases in the Terrestrial Planets
Identifying the mechanisms that drove the evolution of planetary volatiles from primordial to present-day compositions is one of the classic challenges in the planetary sciences. The field bristlesExpand
Isotope composition of helium in ultrabasic xenoliths from volcanic rocks of Kamchatka
The purpose of this work is to refine our knowledge about the nature of helium with a high abundance of the rare isotope3He(3He/4He= 10−5) discovered in terrestrial volcanic gases in 1968. We willExpand
Isotopic composition of the earth's helium and the problem of the motive forces of tectogenesis
The isotopic composition of helium (3He4He = R) contained in underground fluids was studied in different geotectonic provinces. Provincial mean values (R) were estimated by a routine statisticExpand
Mantle helium in the Red Sea brines
HELIUM isotope studies on terrestrial samples have revealed the existence of two helium components which are clearly distinct from atmospheric helium. The first of these, which we term ‘crustalExpand
The role of element distribution in production and release of radiogenic helium: the Carnmenellis Granite, southwest England
Abstract The abundance and isotopic composition of He has been measured in whole-rock samples and mineral separates from the Carnmenellis Granite and compared with circulation fluids from theExpand
Models for Distribution of Terrestrial Noble Gases and Evolution of the Atmosphere
Noble gases provide unique clues to the structure of the Earth and the degassing of volatiles into the atmosphere. Since the noble gases are highly depleted in the Earth, their isotopic compositionsExpand
Helium, volatile fluxes and the development of continental crust
Mantle-derived helium has a substantial primordial component and is readily distinguished from radiogenic “crustal” He by its isotopic composition. For some years it has been known to be escaping atExpand
