... by two SAES GP50 getters operated at 250°C and one at room temperature. Argon was trapped for 20 minutes on an activated charcoal-filled stainless-steel finger cooled to −196°C using liquid nitrogen. Neon was then trapped on activated charcoal in a cryostatic cold head at 30 K for 10 minutes...

... are significantly higher at 2.6–56.5%. 20 Ne can be used as a proxy for the degree of groundwater contact of a gas phase (e.g. Ballentine et al. 1991 ; Ballentine and Sherwood Lollar 2002 ; Barry et al. 2016 ). Neon concentrations similarly show two distinct patterns. Within all the helium-rich NTDZ...

... CO 2 -rich gases point to a chondritic, rather than a solar, origin for mantle volatiles ( Holland et al. , 2009 ). Likewise, Antonio found that the stable isotopes of xenon pointed to a chondritic, rather than a solar, origin, as also indicated by neon and helium isotopes ( Caracausi et al. , 2016...

... ) that are eight orders of magnitude higher than those of the atmosphere or air-saturated water (~5 × 10 –8 ). This observation further confirms helium is nonatmospheric in origin. Neon and argon isotopes of the samples have much narrower ranges that are mostly similar to modern air. In summary, the results show...

... ). Neon (Ne) is one of the most commonly used pressure media in high-pressure studies (e.g., Jephcoat et al. 1986 ; Fei et al. 2007 ; Dewaele et al. 2008 ; Zhuravlev et al. 2010 ; Dorfman et al. 2012 ). It can maintain a better quasi-hydrostatic condition than soft solids (e.g., NaCl, KCl), alcohol...

..., and by quantitatively testing hypotheses for helium source and water interaction. This study demonstrates that PHF helium and nitrogen concentrations result from interaction of a hydrocarbon-rich gas with at least two pore-water masses containing dissolved helium and nitrogen. Neon isotopic ratios demonstrate...
