摘要
The Western Yunnan is just situated in juncture area of the Yangtze,Indosinia and Shan-Thai Microcontinents,with the geosuture zones among them marked by ophiolite suites and blue schists.Agreat number of petrological data support systematic evidences for Paleo-Tethys occurring in the area,andaccording to them,the tectonic evolution is reconstructed.Paleo-Tethys might be a poly-island ocean duringthe Late Paleozoic,and relic oceanic basins developed in Triassic1 Neo-Tethys immigrated westwards intoBurma.The area is an orogenic belt experiencing complicated subduction and violent continent-continent col-lision,and reformed by the younger structures,specially the Himalayan movement.
