根据沉积建造的类型、系列和体态认为楚雄盆地在晚三叠世经历了３个明显的发育阶段：第一阶段为早期聚敛碰撞阶段，发育了黑色页岩建造和碳酸盐复理石建造；第二阶段为构造相对静止期，发育了火山复理石建造和陆源复理石建造；第三阶段为盆地充填阶段，发育了海相磨拉石建造和陆相磨拉石建造。３个阶段中的沉积建造属于次稳定型和非稳定型两大类。 According to the type, series and body state of sedimentary construction, the Chuxiong basin underwent three distinct developmental stages in Late Triassic: the first stage was early convergence and collision stage, the development of black shale and carbonate flysch were developed; The second stage is the construction of relatively quiescent period, the development of volcanic flysch construction and the construction of terrain flysch; the third stage of the basin filling stage, the development of marine moss stone construction and continental moss stone construction. Sedimentary construction in the three stages belongs to sub-stable and non-stable two categories.
