摘要
Tectonic deformation of the Longmen Mountain started during Indosinian,and developed during Yanshanian and Himalayan.The beginning time of deformation was later in the south and east than in the north and west.Deformation intensity was stronger in the west than in the east.At the end of late Triassic,due to the closing of the Qinling Ocean,lateral compression took place from north to south,resulting in the uplift of the Micang Mountain and the subduction of the Ganzi-Litang tectonic belt.Scissor compression is the main generation mechanism for the Longmen Mountain.The main tectonic style is nappe,which can be divided into 3 systems.Fault propagation and fault bend folds are favorable for petroleum accumulation.
