The scope of this paper is to discuss the major constraints posed by lead isotopic ratios with respect to possible metal sources in stratabound ore deposits of the Andean Cycle. This is based on a compilation of all available lead isotopic ratios of ore minerals from stratabound ore deposits. A few additional new analyses are also presented. In the present chapter only main patterns observed on a large regional scale will be dealt with; the reader is referred to the cited publications on the different ore deposits for additional details. Since information on lead isotopic ratios on host rock samples is fragmentary and, is in many cases lacking, the discussion will refer mainly to ore lead data.
