Abstract: This paper deals with the geometry, material composition, deformation metamorphism and kinematic features of the Lancang River tectonic mélange zone in western Yunnan. The authors hold that this mélange zone originated in the Eocene and underwent E W compression in the early stage and nearly N S directed sinistral strike slip in the late stage.
