摘　　要：运用古地磁学方法研究了库车坳陷第三系同沉积褶皱，同褶皱检验发现上新统和渐新统原生剩磁主要是同沉积剩磁，说明该区上新世和渐新世表现出较强的构造活动性；因而，对推断控制库车坳陷油气分布的构造格架和相关的构造形迹有十分重要的地质意义。The authors present here a brief introduction of synse dimentary deformational process obtained from latest paleomagnetic results of Tertiary System in Kuche Depression. The results from synfolding test imply that primary magnetizations of Pliocene and Oligocene are mainly synsedimentary remanent magnetization.According to pleomagnetical data, structural activity is intense during Pliocene and Oligocene.As a result, It has geological significance to deduce structural framework and corresponding structural trace which control distribution of oil and gas in Kuche Depression.
