- Abstract:
- The isotopic composition of 124,126Xe/130Xe, 38Ar/36Ar and Kr isotopes in mantle materials are masked by atmosphere-derived compositions. These isotopes however, are crucial in resolving the origin of volatiles in the Earth and the processes responsible for their incorporation during accretion (e.g. Ballentine, Science 2002). A pilot study of He, Ne and Ar isotopes in CO2 rich natural gases shows clear resolution of both air- and crustal-derived noble gases from magmatic well gases. We propose to analyse 124,126Xe/130Xe, 38Ar/36Ar and Kr isotopes in these and related CO2 well gases. This data will enable us to: 1) Model and quantify deep magmatic degassing processes beneath the crust; 2) Identify the interaction and volatile evolution of the lithospheric mantle with the convecting mantle; and 3) Identify the origin and mechanism of volatile incorporation into the Earth.
