Wrinkle ridge is a kind of linear structures, which distributes most widely in the mare. This paper interpreted high-resolution images of the wrinkle ridges on the eastern edge of Sinus Iridum and comparatively analyzed conditions in other regions. Combining previous geological data and tectonic evolution model, it indicated that the en echelon wrinkle ridges are affected by the substrate of the Sinus Iridum crater edge and the surface basalt lithology. It may have been developed under the radial compressional stress caused by basin subsidence and the shear stress caused by basalt movement. On this basis, this paper discussed the evolution of the wrinkle ridges, and discovered that they still were active in the Copernicus.
