The Ag-Pb-Zn-(Cu) ores formed successively at different levels from magmatic fluids from deep to shallow. The Ag-Pb-Zn-(Cu) ores located at 1400–1600 m levels are formed from the hydrothermal fluids related to the granite porphyry (Fig. 13 b). The sulfides in these ores have higher S and lower Zn isotopic compositions.
