| 摘 要： | 中、下扬子区广为发育的前缘逆向倾滑,后缘正向倾滑和两侧为走滑断裂所限的薄皮层块构造,系挤压和拉张作用处于同一运动系统中,是由岩石的物质分层、能量分层和构造分层作用及层滑运动所致。地壳表、浅层分布的层块构造与深层的块片构造、地体构造和板块构造的倾滑、走滑机制是一致的,并与断裂力学中的滑开型、撕开型和位错构造中的刃型位错、螺型位错的力学机理和运动本质是相同的。

| Abstract: | The thin-skinned layer-block structures confined by the reverse dip-slip fault in a leading edge, normal dip-slip fault in a back edge and strike-slip faults (lateral sinistral and/or dextral fault)widely developed in the middle-lower Yangtze River area, may result from layering of rock materials and energy, and structures as well as layer sliding.
The mechanism for the dip-slip and strike-slip in the layer-block structure in the shallow crust is similar to that in terrane and plate tectonics at depth, and to the origin of the slip-apart and tear-apart fractures in fracture mechanics and the knifeedge and helical dislocations in solid physics. |

| Keywords: | Middle-lower Yangtze River area dip-slip fault strike-slip fault layer-block structure |
