| Abstract: |
| Fluid inclusions tend to objectively record the fluid conditions during the metamorphism and subsequent tectonism. The temperatures and pressures for the fluid inclusion formation are believed to be the significant factors indicating physical and chemical conditions during the fluid inclusion formation. The morphology and compositions of the fluid inclusions from the Xuelongshan ductile shear zone, Yunnan examined in this paper may reflect the genesis, nature and evolution of the fluids from this area. The results of research show that the Xuelongshan ductile shear zone is not only a tectonically deformed zone but also a catathermal and retrogressive metamorphic zone. |
