| Abstract: | This paper discusses the application of the newly developed ELAN 250 I.C.P./mass spectrometer to exploration geochemistry. This instrument combines an inductively coupled plasma with a quadrupole mass spectrometer. The combination of these two existing technologies makes it possible for the first time to perform stable-isotope and elemental analysis rapidly and concurrently.Particular attention is paid to the use of lead isotopes to type Au and base-metal occurrences. Data are presented on galena samples obtained from the Geological Survey of Canada and the Royal Ontario Museum. Consideration is also given to the potential usefulness of Pb isotopes and trace-element data to type mineral occurrences and to identify new ones. |
