摘要
本文简要论述了牙哈断裂构造带的构造特征，认为牙哈断裂本身呈现雁列式断续分布，和在其上发育的一系列串珠状背斜、断背斜及在其两侧伴生的一系列与主断裂或成λ字型构造或平行的小正断裂的主要原因是由于喜马拉雅运动使处于塔里木地台边缘的库车拗陷与南天山断褶带发生挤压扭动，发生的逆时针方向水平扭动和构造运动幅度的差异而产生的。同时又分析了该构造带的构造发育史，认为其发育史有与整个塔里木盆地的发展史截然不同的三个主要时期。
This paper discusses the structural features of Yaha fault structural zone. It points out that the fault structural zone itself appears to be echelon-type and distributed over the area intermittently, a series of string-bead anticlines and fault-anticlines exist on it, and a series of A-type structures or parallel small normal faults are followed in both sides of the zone, the reason for which is that shearing countercloskwise and the discrepancy of the tectonic range were occured as the Kuche depression on Tarim massif margin and South Tianshan mountains fault--fold occured compression-shearing each other as a result of Himalaya orogency. At the same time, this paper analyzes the development history of the structural zone, and concluds that its development history is completely different from that of Tarim basin, having three main periods.
