Metallogeny of Shoshonite-Hosted Copper-gold Deposits in Middle-South Parts of Tancheng- Lujiang Deep Fault Zone and Its Vicinity, Eastern China

摘要

The middle-south parts of Tancheng-Lujiang deep fault zone and its vicinity are an importan locality of Cu-Au deposits related to Mesozoic volcanic-subvolcanic magmatism in eastern china. According to their metallogenic features and ore-forming conditions, copper-gold deposits in this District are ascribed to two groups: the epithermal group which can be further divided into telluri- Um-gold type, quartz-adularia type and quartz-manganoansiderite type; the magmatic hydrother- Mal group which includes porphyry Cu-Au deposit, breccia pipe-porphyry type Au-Cu depsit and Skarn type Au-Cu deposit.
