| Abstract/Notes | Lead isotope data, from a group of seven zinc–lead deposits in Devonian carbonate strata of northeastern British Columbia, have very radiogenic and variable compositions and form a series of parallel linear arrays on Pb/Pb diagrams. These arrays are entirely separate from the less radiogenic and much less variable lead compositions of the Devonian shale-hosted zinc–lead deposits in the laterally adjacent Paleozoic basinal sequence, which themselves define steeply dipping linear trends. Both of these types of arrays reflect multistage histories during the evolution of Pb compositions. One stage may have been a period of residence of Pb in uranium-rich Paleozoic shale, which caused the development of the radiogenic leads that were emplaced later in the carbonate-hosted zinc–lead deposits.Unlike the Devonian carbonate-hosted deposits the "Silver-rich vein" group of deposits is homogeneous in Pb isotope composition. This contrast in the isotopic homogeneity between deposits may reflect differences in the mechanisms by which these deposits formed. |
