Using cooling curves of K-feldspars obtained by specific 40Ar/39Ar step heating procedure and multiple diffusion domain modeling (MDD model), together with results of dating hornblende, biotite, muscovite, and apatite, this research relates the cooling history of 3 areas, from Ejia in NW to Jinping in SE of Ailao Shan-Red River shear zone, and near Hekou (distance about 390 km). The results indicate that the slip distance of Ailao Shan-Red River shear zone is more than 350 km (at least based on the study done within China). And between the end of the left-lateral slip movement and the beginning of the right-lateral slip movement, the uplift of shear zone from SE to NW was homogeneously extended.
