威尔逊循环(英语:Wilson cycle)是一个学说,它描述了在超大陆的合并和分离过程中海洋盆地的打开和关闭以及构造板块的俯冲和分离[1]。威尔逊旋回把板块构造运动分成六个阶段:大陆的分离形成大陆裂谷、新生海洋壳的形成、大陆漂移造成海洋盆地、俯冲开始、洋盆收缩,海盆的闭合造成大陆碰撞[2]。 前三个阶段代表了海洋的扩大,后三个阶段代表了海洋的闭合和山脉的形成[3]

威尔逊循环的阶段: From ten o'clock position clockwise: (10) initial pre-drift extension, (12) rift-to-drift phase, initial opening of an oceanic basin, (2 and 4) seafloor spreading, widening of the basin, (6) subduction of oceanic lithosphere, closure of the basin, (8) continent-continent collision
