| 摘 要： | 依据龙门山中段中生代盆地的基底性质、沉积构造组合和构造变形，论证了川西拗陷是在印支期发育于扬子板块活动大陆边缘的弧背（前陆）盆地，前陆盆地的构造变形是经印支期构造变动和喜马拉雅期叠加改造形成的推覆构造；并讨论了龙门山中段中生代前陆盆地的构造演化历史。

| Abstract: | Based on the characteristics of basement, sedimentary tectonics and tectonic deformation of the basin in the middle Longmen Mountains,this paper proves that the western Sichuan depression is the retroarc(foreland)basin developing in the active continent margin of Yangtze plate during indo Chinese epoch and that its tectonic deformation is the nappe formed by tectonization in Indosinian and superposition in Himalayanian. The paper also discusses the structural evolution history of the foreland basin in Mesozoic. |
