| 摘 要： | 龙门山构造变形始于印支期,经历燕山期和喜山期多次递进变形,构造变形时期具有由北向南、由西向东逐渐变晚,构造变形强度西侧强、东侧弱的特征.晚三叠世末期,随着秦岭洋的关闭,导致由北向南的侧向挤压,使得米仓山构造带开始隆升,与甘孜-理塘构造带俯冲加剧,剪刀式的挤压作用是龙门山形成的动力机制.龙门山构造带主要构造样式是推覆构造,可划分成三种构造体系,有利油气富集的构造样式是断展褶皱、断弯褶皱.

| Abstract: | 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... |
