The data clearly show that most of the Pb in central Andean igneous and ore samples is derived from the local basement, including Pb in ore deposits of the Bolivian tin belt. Some of the isotopic domain boundaries correspond to geologic structures and the residual gravity pattern, as well as to metallogenic boundaries such as the western edge of the Bolivian tin belt.
