Helium and neon isotope geochemistry of some ground waters from the Canadian Precambrian Shield
TLDR
For example, at the Chalk River Nuclear Laboratories in Ontario helium concentrations in ground waters in a Precambrian monzonitic gneiss range from 1.5 × 10−7 to 8.7 × 10 −4ccSTP/gH2O with the 3He/4He ratios ranging from 2.3 × 103.About:

Production, Release and Transport of Noble Gases in the Continental Crust
Chris J. Ballentine,Pete Burnard +1 more
TL;DR: In this article, the authors studied three different mechanisms of noble gas production within the crust: radiogenic, nucleogenic, fissiogenic and fissile gas production, and showed how production ratios are affected not only by the source region radioelement concentration, but also by the spatial distribution and concentration of the target elements.
Journal ArticleDOI
Noble Gases in Lakes and Ground Waters
TL;DR: In contrast to most other fields of noble gas geochemistry that mostly regard atmospheric noble gases as contamination, the authors pointed out that air-derived noble gases make up the far largest and hence most important contribution to the noble gas abundance in meteoric waters, such as lakes and ground waters.

Helium, volatile fluxes and the development of continental crust
R.K. O'Nions,E. R. Oxburgh +1 more
TL;DR: In this article, a steady-state flux of He through the continents that may be estimated from He accumulations in lakes and aquifers is calculated from their 3He content.

T. Torgersen,W.B. Clarke +1 more
TL;DR: The rate of 4 He accumulation in the groundwaters of the J-aquifer of the Great Artesian Basin, Australia has been determined using 14 C and hydrologic ages as mentioned in this paper.

Isotopic Variations in Meteoric Waters
TL;DR: The relationship between deuterium and oxygen-18 concentrations in natural meteoric waters from many parts of the world has been determined with a mass spectrometer and shows a linear correlation over the entire range for waters which have not undergone excessive evaporation.

Primordial neon, helium, and hydrogen in oceanic basalts
Harmon Craig,John E. Lupton +1 more
TL;DR: A primordial neon component in neon from Kilauea Volcano and deep-sea tholeiite glass has been identified by the presence of excess 20Ne; relative to atmospheric neon the 20Ne enrichments are 54% in Kilea neon and about 25% in the basalts The 20Ne anomalies are associated with high 3He/4He ratios.
Journal ArticleDOI
Determination of tritium by mass spectrometric measurement of 3He
TL;DR: A new technique for analysis of environmental tritium is described in this paper, which consists of mass-spectrometer measurements of 3He allowed to accumulate for suitable times in degassed samples of water sealed in containers made of Corning type-1720 glass.

“Excess air” in groundwater
T.H.E. Heaton,J.C. Vogel +1 more
TL;DR: The concentrations of dissolved gaseous nitrogen and argon in groundwater from a number of areas in South Africa are in many cases higher than the concentrations to be expected for atmospheric equilibrium.
