摘　　要：通过对构造沉降、断裂活动、岩浆活动、构造应力场等分析，认为台西南盆 地晚新生代地质演化存在两个旋回，即渐新世一中中新世受南海扩张控制、陆缘主 动裂陷－沉降旋回和晚中新世－第四纪受台湾弧－陆碰撞影响、陆缘被动拉张－活化 旋回。By analyses of characteristics of tectonic subisdence, fault activity, magmation, and tectonic stress field, it is suggested that there are two cycles of geologic evolution of Taixinan Basin in lute Cenozoic Era. One is the active rifting-subodence cycle of continental margin which be controled by the spreadig of South China Sea in Oligocene -Middle Miocene. The other is the negative rifting-reactivity cycle of continental margin which be influenced by the collison between the arc and the continental margin of Taiwan in Late Miocene-Quaternary.
