Based on petrological and trace element geochemical studies as well as an analysis of oreforming rock bodies and wall rocks for different types of ore deposits, the present paper has probed into the relationship between Mesozoic volcano-magmatic activity and metallization. It is held that Late Jurassic volcano-magmatic activity provided favorable wall rock and structural space for the ore-forming process, and that Early Cretaceous magmatic activity supplied ore-forming rock bodies as well as thermodynamic conditions. The subvolcano-magmatic intrusion of the latter period played the major role and reacted with different wall rocks, forming a series of ore deposit associations composed of porphyry copper and molybdenum deposits and epithermal silver, lead and zinc deposits.
