| 摘 要： | 库车再生前陆盆地位于塔里木盆地的北缘,其沉积和构造特征具有典型的前陆盆地性质.库车再生前陆盆地开始形成于吉迪克组沉积早期(距今25Ma),叠置于晚二叠世-三叠纪前陆盆地之上,是始新世末印度-西藏碰撞的远距离构造效应所致.其中的前陆逆冲带是由浅部和深部两个层次的构造组成的,其构造特征具有不一致性和不协调性.库车再生前陆逆冲带内的台阶状逆断层及其相关褶皱都是伴随着中新世以来的造山运动形成的,由山前向盆地以背驮式渐次连续扩展,自渐新世晚期一直持续到现在.印度-西藏碰撞作用引起的陆内俯冲及壳内拆离-缩短作用是库车再生前陆盆地的形成机制.

| Abstract: | The Kuqa rejuvenated foreland basin (KRFB) is located along the northern flank of the Tarim basin. The characteristics of sedimentation and structure reveal a typical foreland basin. The KRFB, superimposed on the Late Permian Triassic foreland basin, was created from the early sedimentary period of Jidike formation (25Ma B.P.), and resulted from the remote tectonic effect of India Tibet collision. The thrusts in KRFB consisted of shallow and deep level structures which were inconsistency and disharmonic in varied levels. The flat ramp faulting and fault related folding in KRFB migrated from foothill of Tianshan Mountains to the basin in sequence of piggyback, and they were formed during orogeny from the Late Oligocene to now. The intercontinental subjection and intracrustal decollement shortening which resulted from India Tibet collision were effective forming mechanism of the KRFB. |
