本文以地层学的观点分析了长江中、下游地区早期中生代地层沉积及构造特征后,指出地层分布上虽存在“脱节”与“分离”,构造形态上存在差异和不协调,但在总体上又是统一和相成的,同于处一个构造体系之中。作者认为本区印支期地壳运动是一种和缓的、以升降作用为主的运动;地壳变形主要表现为隆起与拗陷。早期地壳上升(相当于金子运动)—由浅海逐渐变为陆地,晚期地壳上升(相当于南象运动)一形成了沉积间断和风化剥蚀,其中并发生构造运动的东向迁移和沉积作用的北向迁移。
After analyzing the Mesozoic sedimentary and tectonic features in the middle and lower reaches of the Yangtze River from the viewpoint of stratigraphy, this paper points out that although there are “disjoint” and “separation” in the stratigraphic distribution, there are differences and uncoordinations in the structural forms, but on the whole, Is unified and complementary, with the same place in a structural system. The author thinks that the Indosinian crustal movement in this area is a kind of moderate movement that is mainly composed of ascending and descending movements. The crustal deformation mainly shows uplift and depression. Early crustal uplift (equivalent to the movement of gold) - from shallow sea to land gradually, late crustal rise (equivalent to the Southern Movement) formed a sedimentary discontinuity and weathering and erosion, in which the northward direction of tectonic movements and sedimentation occurred migrate.
