Lithophile elements noble gases

Further progress on the origin and nature of rare gases in the lithospheric mantle may be obtained from studies that combine evidence from fluid inclusions, textures, lithophile trace element isotope systematics, and major element variations to understand how noble gas concentrations and isotopic compositions are introduced and modified within the lithosphere.
