註釋The western Newfoundland carbonate platform has been the site of lead-zinc exploration for several decades, resulting in the discovery of several dozen occurrences and one commercial producer. Geological information on these occurrences, collected by industry, government, and university geologists, is scattered among government assessment files, company reports, and university theses. This study merged this information on more than 40 of these occurrences with new on-site observations and follow-up laboratory investigations. The occurrences are grouped into three main types, each with a distinct mineralogical and textural characteristic, with host rocks ranging in age from Middle Cambrian to Early Carboniferous.
