吉林省东部山区的北部地区,隶属天山一兴安地槽褶皱区。长期以来认为二迭纪末的华力西晚期构造运动是这一地区地槽全部活动的结束期,未曾有过争议与讨论。近年,我们在吉林省东部山区开展1:20万区域地质调查,构造地质基础实际资料表明,本区二迭纪末的华力西晚期运动并 The northern part of the eastern mountainous area of ​​Jilin Province is subordinated to the fold zone of the Anti-Tian-Tianshan Mountains. For a long time, it is considered that the Late Permian Late Waringian tectonic movement was the end of all the activities of the trough in the area, and no controversy or discussion was ever held. In recent years, we conducted a 1: 200,000 regional geological survey in the eastern mountainous area of ​​Jilin Province. The actual geological structural data show that the late Waringian Late Movement of the Late Permian
