Abstract | The Proterozoic Purcell Basin in Canada (Belt Basin in U.S.A.) contains numerous Ag-Pb-Zn vein deposits and stratiform massive sulphide Pb-Zn-Ag deposits. In the Coeur d'Alene district in Idaho, veins
have been divided in two types: Proterozoic Pb-Zn-rich veins and Mesozoic Ag-Pb-Zn rich veins. Based on previous Pb-isotope work, the vein deposits of the Purcell Supergroup in British Columbia can be divided into the same two groups. Representative
veins of the Purcell Supergroup having a Proterozoic and Mesozoic Pb-isotope signature were sampled during the 2006 field season and are described in this paper. Preliminary results show that the Pb-Zn-rich veins are massive and only present in the
Aldridge Formation, and the Ag-Pb-Zn-rich veins mainly consist of galena in a quartz gangue, and crosscut various strata of the Purcell Supergroup. Further work will attempt to characterize the sources of the mineralizing fluids, and the O, S, C,
and Pb isotopic composition in both types of veins and compare them to the Coeur d'Alène district in Idaho, U.S.A. |
