Here I reported new structural data to answer above question, including field section observations and geologic map with large scale in a key area, accompanying with detail microstructural observations, quartz C-axial fabric analyses, and tectono-thermogeochronology (40Ar/39Ar and zircon SHRIMP U-Pb method). Taking available previous data into account, following progression is achieved:1. Completely rebuilding the post late-Paleozoic deformation history of the Harlik MountainFive stages of deformation were identified:(1)pre-Permian compression deformation which may have resulted from pre-Permian subduction;(2) earlier Permian post-collision extension;(3) middle Permian west-east directed dextral slip shearing;(4) later Permian nearly N-S compression deformation; and (5) later Cenozoic intra-plate N-S compressional deformation.
