摘要
对龙门山中北段东缘地区印支运动晚幕的性质有两种看法,即褶皱运动和局部上升运动。经对该次构造事件之不整合的性质再研究后,认为其为一次掀斜运动。形成该掀斜运动的机制为从晚三叠世晚期至中侏罗世中期区域水平挤压力减小而引起龙门山前陆盆地岩石圈均衡回返上升。
There are two views on the properties of the tectonic movements (i.e. folding and uplift movements ) in the east margin of the middle and northern Longmen Mountains at the end of Triassic period. By analyzing the unconformity of the movement again, the author thinks that it is not folding, but tilting and uplifting movement. The forming mechanism of the movement is that the decreasing of the lateral pressure exerted on this region resulted in the isostatic uplift of the lithosphere of the Longmen Mountains foreland basin.
