Distal Pb-Zn-Ag veins associated with the world-class Donggou porphyry Mo deposit, southern North China craton

• The Mo and Pb-Zn-Ag mineralization in the Fudian ore field formed contemporaneously.
• Trace element and Pb isotopes of pyrite confirm a magmatic origin for the Pb-Zn-Ag veins.
• The two types of mineralization formed a typical porphyry-related metallogenic system.
• The model has implications for further exploration of Mo-Pb-Zn-Ag resources in the area.
