| 摘 要： | 兴地断裂是塔里木盆地东北缘十分重要的大型控盆断裂,该断裂对塔里木盆地东北缘地层发育、构造古地理、库鲁克塔格断隆-满加尔坳陷的构造演化等具有重要的控制作用.根据断裂带中糜棱岩、构造角砾岩、构造透镜体、断层崖、断层三角面等不同构造形迹的性质,结合断裂对区域地层发育和构造古地理的控制作用,对断裂的变形期次和性质进行了划分,并讨论了断裂的演化历史及其形成的地球动力学背景.断裂经历了元古代—新生代漫长的构造演化历史,发生了多期次不同性质构造活动.其构造演化主要包括形成期(Pt2);伸展期(Pt3—O);挤压反转期(O2末期和O3末期);左旋压扭期(Pz2末期)、逆冲推覆期(E末期—Q3)和右旋张扭期(Q4)6个构造演化阶段. |

| Abstract: | The Xingdi fault is a large controlling basin fault which plays an important role in the northeast margin of Tarim basin.The fault controls the development of stratum and the tectono-palaeogeographic and tectonic evolution of Kuluketage uplifted block known as the Manjiaer depression in the northeast margin of Tarim basin.The periods of deformation,the evolutionary history and the geodynamic background are discussed in this article with reference to the diverse structural traces of mylonite,tectonic breccia,tectonic lens,fault cliff and terminal facet in the fault zone.The fault has gone through a long history of tectonic evolution from Proterozioc to Cenozoic and has produced periods of tectonic activity of diverse nature.The tectonic evolutionary history includes six main periods,namely,the formation stage(Pt2);stretching period(Pt3-O);compressive inversion period(the last stage of O2,O3);sinistral compressive-shear period(the last stage of Pz2);thrust-nappe period(the last stage of E-Q3) and dextral tenso-shear period(Q4). |
