| 摘 要： | 通化中生代断陷盆地（前人称三源浦盆地）以频繁的沉积作用和火山作用为特征，形成了多旋回的火山—沉积序列，表现为火山爆发相、溢流相与冲积扇相、湖泊相的反复交替，并发育了湖相火山碎屑浊积岩系〔１〕。盆地演化经历了早期非补偿阶段、早期熔浆充填期，火山喷发期后非补偿沉积阶段、晚期熔浆充填期，构成二个大的火山—沉积旋迥。

| Abstract: | The Mesozoic fault basin (named Sanyuanpu Basin by the formers),is characterized by the frequent sedimentations and volcanisms.So,multicycle volcanos sedimentary succession were formed.showing alternative volcnaic explosion facies,overflow facies,sedimentary fan facies and lake facies.And a developed pyreclastic turbidite serises were formed. The basin evolutions occurred in the early starved stage,early lava filling period.Post volcanic eruption starved sedimentary stage,and late lava filling period. Two large volcanic sedimentary cycles were formed. |
