...; Burnard 2002 ). The presence of primordial 3 He and elevated ratios of helium to atmospherically derived neon (i.e. He/Ne) can be used to apportion small contributions ( c. 1%) of mantle-derived fluids in shallow groundwater, natural gas or other crustal fluids ( Oxburgh et al. 1986 ; Poreda et...

...Z. Top; W. B. Clarke Abstract Dissolved helium and neon, the 3 He/ 4 He isotope ratio, and tritium concentrations were measured in samples collected from 107 lakes and ponds in central Labrador during 1975 and 1976. Excess 4 He values relative to solubility equilibrium, and tritium- 3 He residence...
