Diagrams of ²⁰⁷Pb/²⁰⁴Pb versus ²⁰⁶Pb/²⁰⁴Pb and ²⁰⁸Pb/²⁰⁴Pb versus ²⁰⁶Pb/²⁰⁴Pb showing the Pb isotopic compositions of sulfide minerals from the Keyue and Zhaxikang Sb–Pb–Zn–Ag deposits; reference evolution curves of Lower Crust, Upper Crust, Mantle, Orogenic Belt, and Ocean Island Volcanic Rocks are also displayed (modified from Zartman and Doe [79]).
