对胶北．辽东和吉南地区古元古代层状岩系第一系构造变形作的详细研究和综合分析，并以此为典型实例，提出了古元古代拉伸构造模式，即隆起一顺层分层滑脱构造模式。该模式由核部隆起和上部盖居及两者之间的拆离型韧性剪切带三部分组成。核部隆起常由岩浆隆起或基底隆起构成，上部盖层内发育有顺层分层滑脱构造体系，由底部主滑脱面和内部次级滑脱面、低级滑脱面及其间的流褶居和片理化带构成，靠近核部隆起的盖居表现为正向滑脱，而滑脱前缘则表现为反向滑脱，具有滑覆特征。该模式一般发生在大规模收缩造山作用之前，由于区域拉伸作用，导致壳下地任上隆，形成岩桨隆起或基底隆起，使上覆盖层岩系重力失稳，发生滑脱，内部横向构造置换强烈，形成透入性片理，且平行区域地层层理
On the plastic North. A detailed study and comprehensive analysis of the tectonic deformation of the Paleoproterozoic stratigraphic series in the Liaodong and Kyrgyzstan regions has been made. Taking this as a typical example, the ancient palaeo-extensional tectonic model has been proposed, ie, Construction mode. The model consists of three parts: the uplift of the core part and the detached-type ductile shear zone between the two parts. The upwelling of the core is usually composed of a magmatic uplift or basal uplift. There is a stratified slip-detachment system in the upper caprock, which is composed of the bottom major slip surface, the inner secondary slip surface, the low-level slip surface and the stream folds between them Belt composition, near the nuclear uplift cover home performance for the positive slippage, and slippage leading edge showed reverse slippage, with sliding features. This model generally occurs before large-scale shrinkage orogeny. Due to the regional stretching, the uplift under the shell leads to the formation of rapier uplift or basement uplift, which destabilizes the gravitational force of the overlying caprock and causes the occurrence of slippage and internal transverse structural displacement Intense, the formation of penetrative film, and parallel stratification of strata
