| 摘 要： | 礼岷盆地是晚古生代在扬子板块北缘被动陆缘之上发育起来的前陆盆地。该盆地经历了早期的深海—半深海复理石沉积和晚期的陆相磨拉石沉积 ,其演化过程中主要遭受了三期构造变形 ,即 :早期固态塑性变形 ,中期区域褶皱及走滑变形和晚期逆冲推覆、剪切机制下的复杂变形

| Abstract: | Liming basin is a foreland basin developed on the passive continent margin of north margin of Yangtse platform during late Paleozoic Era. The basin experienced early deep marine semi deep marine flysch sedimentation and later continental molasses sedimentation and was subjected to three periods of tectonic deformations during its evolution. These were early solid plastic deformation, middle stage regional fold and sliding deformation and later complex deformation under thrust nappe and shearing mechanism |

| Keywords: | Liming foreland basin tectonic evolution tectonic deformation |
