Abstract: The East China sedimentary basins are believed to be formed by extension rifting simultaneously with the process of uplifting, subsiding, faulting and deposition. Controlled by normal faults(growth faults), they assume the general character of graben-horst or semigraben-semihorst. No apparent compression fold can be found in these basins, A classification of local structures produced by gravity movements, both lateral and vertical, is given in reflection of the influence of gravity on the formation of different types of structures.

摘要： 我国东部沉积盆地是在引张背景下形成的。盆地中边隆起、边沉降、边断裂、边沉积,构造作用与沉积作用同步发生。盆地结构一般呈地堑一地垒式或半地堑一半地垒式,边缘受正断层(生长断层)控制。因此,这类盆地无明显的挤压褶皱变形,局部构造的成因主要受重力构造作用的侧向运动和垂向运动所控制。
