| Mineralization Environments of the Cu Polymetallic Deposits in the Liupan Shan Arc Structure Belt |
| The Liupan Shan arc structure belt,located in the northeast edge of Qinghai-Xizang plateau, has gone through a whole geological and structural evolution process which was named "Wilson cycle" since Sinian-Cambrian. The mineralization types are different in different evolution periods. During the continental rift and plate subduction period, the main mineralization is volcanic massive sulphide type at sea floor and tectonic alteration rock type which was related with ductile shear zone. While during the collision orogenies and continental orogenies, the main mineralization type is layer-like hydrothermal deposit which was related with large thrusting structure. It is very clear that different tectonic evolution stages reflect different minealization environments. |
