| 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 g... |
