摘要
松辽盆地是大型中- 新生代陆相沉积盆地,具下断上坳双重结构。基底形态继承了海西期近 E W 向构造面貌,基底断裂控制了盆地 N E 向展布,总体上形成了北东向分带、南北向分区的构造格局。基底断裂的多期活动和构造形变反映出应力场的演化特征,同时控制了盆地的沉积和岩浆活动,改变了盆地的内部结构。
Song Liao basin is a big model basin with the Cen ozoic EraCo-ntinental deposit, It has fault down and col up two entrely texture Basal form has inherited Hai xi Qi Jin EW tecto nic face; Basal rift has controlled NE unfold Total it has formed east-north divide in to group and South-north area' s tectonic pattern Permanently exercise and tectonic deformation of basal rift have reflected evolution feature s of field stress Meanwhile, It has controlled deposit and magma's exercise of basin It has changed inside texture of basin
