摘要:
提要:柯坪断隆内断裂发育,笔者根据野外及地震数据对各主要断裂和二级断裂进行了分析,认为柯坪塔格断裂形成于晚第三纪,沙井子断裂早期与柯坪塔格具有不同的发育历史,阿合奇断裂形成于挤压而非走滑的背景下,皮羌断裂和印干走滑断裂其实是协调作用的捩断层。萨尔干断裂是一条假走滑断层,实际上应该是一条撕裂断层。在挤压背景下形成了二类主要的断裂构造组合样式:叠瓦推覆体、构造窗。笔者认为柯坪断隆上的构造其实是印度板块和欧亚板块远程碰撞造山和板内变形的一种表现。

Abstract:
Abstract: There are a lot of faults in the Kalpin fault uplift. Through field work and interpretation of seismic reflection profiles and Landsat images, the authors consider that the Kalpin Tag fault formed in the Neogene and had a different early evolutionary history from the Shajingzi fault. The Akqi fault formed by compression, rather than by strike slip. The Piqanlik and Yingan strike-slip faults are tear faults that exert concerted effect on the whole zone. In the field, the authors found that the Shargan fault is a false strike-slip fault and in fact should be an out-of-sequence fault. Under compression, two kinds of main fault combination were formed in the Kalpin fault uplift: imbricate thrust sheets and tectonic windows. From an analysis of the main faults in the Kalpin fault uplift, the authors consider that the Cenozoic structures in the Kalpin fault uplift are actually a manifestation of orogeny due to remote collision between the Indian plate and Eurasian plate and intraplate deformation.
