Abstract

"This investigation of the abundance and isotopic composition of noble gases in helium-rich gas wells was undertaken in order to obtain new data which might be used to elucidate the origin of isotopic anomalies of noble gases in the atmosphere. Since noble gases are presently leaking to the atmosphere (Damon and Kulp, 1958a; Bieri et al., 1967-) the isotopic composition of the present atmosphere is not static. The direction of change, and ultimately the origin of anomalous noble gases, might therefore be discovered in studying the noble gases presently leaking from the earth. Since the two major noble gas isotopes generated within the earth today are radiogenic He⁴ and Ar⁴⁰, these two gases can be used as tracers to show that a sample contains noble gases leaking from the earth. the primary objective of this study was to accurately determine the isotopic composition of other noble gases accompanying these two tracer isotopes to see if they might contain evidence of the direction of evolution of the noble gases in the atmosphere"--Introduction, page 1.
