THE Shangmanggang gold deposit is located at the southwestern corner of Yunnan, China. The deposit occurs along the southwest-trending Shangmanggang Fault. Near the surface, the hanging wall of the fault consists of sandstone and mudstone of the Middle Jurassic Mongga Formation (J_(2m)), and also severs asthe hanging wall of the gold orebodies. The footwall of the fault is composed of dolomitite locally intercalated with medium-bedded limestone of Lower Permian Sazipo Formation (P_(1s)). In the depth, the faultcut into strata of the Sazipo Formation (P_(1s)). The deposit is characterized by intense clay alteration,which is similar to the Mercur Gold Deposit, Utah of USA, and by unique hydrothermal pinnacle karsl,
