Noble gases in Canadian Shield groundwaters from the Con Mine, Yellowknife, NWT
Dissolved noble gas concentrations in Canadian Shield groundwaters from various depths of the Miramar Con Mine, Yellowknife, were examined for paleotemperature information and isotopic ratios. A high-vacuum stainless steel line with reactive gas gettering, isotope spike dilution and quadrupole mass...
