| 摘 要： | 中晚泥盆世右江被动陆缘裂谷盆地北部发育北西向张性同沉积断裂和北东向走滑断裂.以层序充填动力学"构造控盆、盆控相,不同相带的时空配置形成层序的不同样式"的研究思想为指导,通过点、线和面相结合的方法,分析层序充填过程中充填物质组成和沉积相带演化特征.层序充填过程揭示了海侵期和高位期均发育两期脉动性的构造活动,且海侵期呈逐渐增强趋势,具有随北东向拉张作用增强诱发北西向同沉积断裂的时序性特征,并进一步佐证了右江盆地北部中晚泥盆世为盆地北缘台盆深入台地内,盆地中台、盆相间的沉积格局,且构造作用的时序性导致不同时期沉积格局展布的差异性. |
| 关 键 词： | 右江盆地 中晚泥盆世 层序充填 沉积格局 |

| Abstract: | Northern Youjiang passive continental margin rift basin developed NW-trending tensile synsedimentary faults and NE-trending strike-slip faults in Middle-Llate Devonian period.Guided by dynamics of sequence filling and combined with single profiles,profile correlation and plane changes,the authors analyzed filling material and evolution characteristics of sedimentary facies in the process of sequence filling.A study of the process of sequence filling reveals that there were two pulsing tectonic activities in... |
