摘要
Based on systemic researches on unconformity, tectonic dating and deformation of Jurassic and Cretaceous in different locations of the middle-upper Yangtze region, the Yanshan Movement was divided into 4 stages: the end of Middle Jurassic (Ⅰ), the end of Late Jurassic to the beginning of Early Cretaceous (Ⅱ), the end of Early Cretaceous (Ⅲ) and the Late Cretaceous (Ⅳ). The Yanshan Movement was significant for tectonic transformations in the middle-upper Yangtze region. Tectonic movements during the early stages (Ⅰ and Ⅱ) were characterized by multi-direction compression and thrusting,while those of the late stages (Ⅲ and Ⅳ) held the structural features of ’western compressing and eastern extending’ with differences in basin-mountain relationship, deformation pattern and geodynamic mechanism.
