During late Mesozoic-Cenozoic, HYS inversion structure in Tuha basin underwent the following main tectonic evolution phases: tensile stretch, compressed uplifting, extensional depression and severely compressed folding.

A suite of volcanic associations with the flysch sediments derived from recycled orogens was successively accumulated in the basin during the Late Triassic due to the extension and convergence of the Garze Litang Ocean and the convergence and collision of the Jinshajiang Ocean.
