Abstract: The structural superimposition and transposition of the Sinian strata discovered by the author recently have been studied using the principle and method of the structural analysis, and five generations of structural deformation have been distinguished. It is thought that the Sinian System is old basement that has undergone multi stage, multi system and multi level structural deformation. This structural analysis provided necessary basic data for the study of the structural evolution of the North Qilian orogenic belt.
