The stress analysis during the Late Jurassic (Duodigou Fm., Linbuzong Fm. and Suowa Fm.). (Early stage, the decomposition stress reflects mantle convection, leading to the uplift of the Central Uplift. Late stage, the decomposition stress of the South and North Qiangtang blocks is uniformly oriented towards the north, reflecting the northward compression of the Songpan-Ganzi Terrane by the Qiangtang Block.)
