Deformation Regimes and Low-rank Paleotectonic Stresses of the Western Tien Shan in the Mesozoic – Cenozoic

Research on the Western Tien-Shan reveals alternating phases of compression and extension, providing critical insights into its Mesozoic–Cenozoic geodynamic evolution. By analyzing fracture systems in rocks of varying ages, scientists reconstructed paleostress fields for distinct time intervals: Permian-Triassic to Middle Jurassic, Middle-Late Jurassic, Late Jurassic–Early Cretaceous, Late Cretaceous–Paleocene–Eocene, and Oligocene–Quaternary. This approach leverages the superimposition of fracture systems, where later fractures influence older rocks, enabling accurate stress field reconstruction even in younger Quaternary deposits. The study addresses long-standing debates on the region's tectonic development and offers a foundation for refining its tectodynamic model.
