| 摘 要： | 柴达木盆地古近纪处于弱伸展坳陷阶段, 发育河湖相为主的沉积; 新近纪上干柴沟组沉积时期由于幔源岩浆的活动使盆地以沉降作用为主, 达到全盆最大湖泛面, 发育湖相为主的沉积; 上新世以来盆地发生了多次构造运动, 构造变形的几何学和运动学表明: 盆地的沉积受走滑冲断构造的控制和改造, 发育河相、湖相、冲积、洪积、风积等多种类型的沉积体系。

| Abstract: | The Paleogene in Qaidam basin is in stage of weak-spreading depression, dominated by fluvial-lacustrine deposit. In Ganchaigou formation of the Neogene the active mantle source rock-magma resulted in widely depressed process, occurring the largest lacustrine overflow and deposit. The muhi-tectonic movements since Pliocene in this basin took place, causing the structural deformations in geometry and kinematics. It is concluded that the deposition in Qaidam basin is controlled and reconstructed by strike-slip thrust structures, thus developing such multiple sedimentary systems as fluvial, lacustrine, alluvial, pluvial and aeolian deposits. |
