Indosinian movement of the Qinghai-Tibet region can be divided into two phases, phaseⅠ refers to tectonic movement happened during early Norian period Late Triassic; phase II refers to the tectonic movement which occurred between the Late Triassic Rayleigh period and Middle Jurassic early Bajociant period.
