Large stratiform, syngenetic deposits commonly yield galena-lead isotope 'model' ages that agree closely with the stratigraphic ages of their host rocks. However, analyses in Table 1 from stratiform,shale-hosted deposits (located on Fig. 701 of Cambrian to Devono-Mississippian age in or adjacent to the Selwyn Bar,in in British Columbia and Yukon Territory do not give reasonable ages if the mode...
