| 摘 要： | 选取黔西南地区上扬子碳酸盐岩台地—右江盆地的三叠系剖面进行层序划分对比，并重点对台地边缘剖面进行研究，将三叠系划分为8个三级沉积层序。在此基础上，通过与Haq等列出的三叠纪生物地层时代进行对比，建立了黔西南地区三叠系层序充填格架。根据三级沉积层序自下而上的发育组合将三叠系划分出3个二级层序：SS1、SS2、SS3。本区层序充填特征亦反映了印支运动的3个幕次。印支Ⅰ幕，右江盆地为欠补偿型被动大陆边缘阶段，以构造沉降作用为主；印支Ⅱ幕，右江盆地进入过补偿型前陆发展阶段，由于南部板块碰撞的加强，沉积中心向西北迁移；印支Ⅲ幕，随着扬子陆块的全面隆升，西部盆地和东部台地区抬升消亡。

| Abstract: | The Triassic sections across southwestern Guizhou of upper Yangtze carbonate platform-Youjiang Basin are selected to correlate the consequences，the study also focuses on the sedimentary characteristics of the platform marginal facies.According to the research above，the Triassic is divided into 8 third-order sedimentary sequences.The Triassic sequence filling framework is established by comparing the Haq biostratigraphic data.Three second-order sequences are divided，SS1，SS2，SS3，which are in accordance with genetic stratigraphic combination of third-order sedimentary sequences.The sequence filling characteristics of studied area also reflect three Indo-China movement episodes.Youjiang Basin came to the stage of undercompensated passive continental marginal development during the Indo-ChinaⅠepisode，Youjiang Basin to the stage of overcompensated foreland development during the Indo-ChinaⅡepisode，the sedimentary center switched to the northwest as a result of the strengthening of southern plate collision,with all-round uplifting of the Yangtze block during the Indo-China Ⅲ episode，the western basin and eastern platform demised. |
