| 摘 要： | 对北天山山前四排褶皱丘陵的地貌特征、组成地层与构造特征进行了研究，在此基础上探讨了山前褶皱丘陵的演化历史。第一排褶皱形成于晚第三纪中新世。上新世晚期，早更新世初期，第二排褶皱开始形成。早更新世晚期，中更新世初期，第三排褶皱开始形成。晚更新世晚期，至全新世以来，第二排褶皱与第三排褶皱一直在持续隆升，同时第四排褶皱也开始形成。

| Abstract: | Four fold hills in the north margin of Tianshan Mountains are studied. Based on landform, stratum, and tectonic of fold, the evolution history of fold is discussed. The first fold came into being at the Miocene epoch of late Tertiary Period. The second fold developed between late the Miocene and the initial stage of Early Pleistocene. The third fold developed between late Early Pleistocene and early Middle Pleistocene. The second fold and the third fold had been uplifting from later period of Late Pleistocene to Holocene,and the forth fold came into being at the same time. |
