旋转断层

反S型构造与枢扭走向旋转断层的修改

Modify of the " opposite S " structure and the pivotal strike rotation fault

多世代旋转正断层对断陷盆地沉积迁移的控制&柴达木早、中侏罗世盆地性质

Control of Multi-generation Rotary Normal Faults on Sediment Migration in Rift Basin : An Example from the Early and Middle Jurassic Qaidam Basin

下侏罗统与基底接触带发育的鱼鳞式构造，为地壳不均匀隆升时，多世代旋转正断层先后切割所致。

Fish-scale-like structures formed at the contact surface between lower Jurassic and basement might result from mutual incision of multi-generation rotary normal faults in turn because of asymmetrical uplift of crust .

断层岩在平面上分带特征明显，可划分为碎裂岩-节理密集带，磨砾岩-剪切旋转带和断层泥-局部压溶带等三个带。

The fault exists obviously in three bands : cataclasite concentrated joint band , worn braciation shearing rotation band and gouge partial pressure solution band .

旋转平面状正断层；

2 , rotational planar normal fault ;

中国东部拉张区变形期间发育的正断层，按其几何形态和运动学特征的差异，可确定为四种类型：1.非旋转平面状正断层；

Based on geometric and kinematic characteristics the normal faults in East China can be grouped into four kinds . 1 , non-rotational planar normal tault ;

结果表明，旋转平面状正断层围限块体的滑脱深度与脆韧性转换带上顶面深度一致，为10&15公里；

The calculated result shows that the detachment depth of the tilted block controlled by rotational planar normal fault is about 10-15km , which is the same as the depth of the top surface of brittle-ductile transition zone ;
