Abstract: The study area lies in central Eurasian plate,prone to earthquakes.There were 655 earthquakes with a magnitude of 4.7 or more from 1600-1981.By the end of the Paleozoic,this continent had been formed.Since the Pliocene,large-scale uplift has occurred in the Tianshan mountian;the Kunlun mountians and the Qinghai-Xizang Plateau and molasse conglomerate (Q₁^X) have been piled upon the piedmont.In responding to the Early Pleistocene tectonic movement molasse conglomerate was de-formed to result in regional unconformity between Lower and Mid Pleistocene.Since the Miocene the crustal activity in this area has been charecteristic of intermittent uplifting,subsiding and faulting.

摘要： 本文论述了新疆地震构造特征。对活断层的类型、特征进行了讨论。提出了新疆第四纪构造应力场和现今应力场是一致的,为一近南北向水平压应力,这种压应力来自印度次大陆对欧亚大陆的碰撞。最后讨论了大陆内部断块边界的两种类型,走滑型块间边界和拗-断型块间边界,分别与转换型大陆边缘和陆壳板块互相碰撞的板缘力学机制、活动属性等均很类似,都是强震易于发生的场所。
