| 摘 要： | 断裂带左旋运动起始于新构造运动。早更新世丽江盆地形成之后,斜向穿过丽江盆地的丽江-剑川断裂带对丽江盆地形成现今形态有很强的改造作用。丽江-剑川断裂带最新的一次活动应在早更新世后,以脆性变形为主,韧性变形为辅的断裂带,近期活动深度不很大。

| Abstract: | The cause of left-lateral movement is the neotectonics.After the formation of Early Pleistocene Lijiang basin,the Lijiang—Jianchuan fault zone which diagonally cuts through the Lijiang basin has a very strong reformation of the present morphology of it.The newest activity of Lijiang—Jianchuan fault zone must be after Early Pleistoncene.The Lijiang—Jianchuan fault zone is a fault zone formed by the major brittle deformation and the minor ductile deformation.Its recent activity range isn’t very deep. |
