| 摘 要： | 伴随大型走滑断裂系的运动,可以产生出乎预料的铅直断距。由于大型走滑断裂的运动矢量只是近水平的,沿着大型走滑断裂系发生的数百公里的走滑使得微小的铅直运动分量积累成十几公里至几十公里之巨的铅直断距,足以使中-下地壳的岩石抬升出露。通常,大型走滑断裂系活动时,它的水平位移速率很大。因此,伴随它的垂直位移速率也非常可观。大型走滑断裂系复杂的几何特征和运动过程造成局部地段的隆升突出。大型走滑断裂系的运动对中国东部及邻区现今构造格局的形成和高压-超高压岩石的形成、抬升、剥露起了重要作用。

| Abstract: | Accompanying enormous strike-slip faulting, an unexpected amount of itsvertical slip can be achieved, which is because the displacement vector isapproximately horizontal in the fault planes of a huge strike-slip fault system, aseveral hundred km strike-slip displacement of the fault system causes its verticalslip to reach over ten kms or a few ten kms so that middle or lower crustal rocksmay be uplifted and exposed. The sophisticated geometry of a strike-slip fault system and its displacement process demonstrate uplift even 'more in someparticular segments of the fault system. Studies of famous huge strike-slip fault systems worldwide give strong backing to the conclusion of the present paper.The enormous sinistral slip in eastern China and its adjacent areas haveplayed an important role in formation of their present regional tectonic frameworkand uplift as well as exposure of high pressure-ultrahigh pressure metamorphicrocks. |
