| 摘 要： | 南盘江盆地中的大贵州滩为一个自晚二叠世末期开始发育,至晚三叠世初期停止生长的孤立型碳酸盐岩台地。早期的研究工作主要集中于台地内部、北部斜坡和盆地边缘,并认为大贵州滩下三叠统地层格架的几何形态近于对称。本次研究以下三叠统岩石地层对比为基础,借助早三叠世期间δ13C波动频繁且幅度较大的特点进行化学地层对比后发现：台地南缘二...

| Abstract: | The Great Back of Guizhou in Nanpanjiang basin is an isolated carbonate platform,which developed from the end of Late Permian Epoch to the early of Late Triassic Epoch.The early research mainly concentrated in the inside of platform,north slope and basin edge,it＇s also thought the geometry of the stratigraphic framework is almost symmetric.This study is basis on the rock stratum comparison of Lower Triassic Series,for the feature of the δ13C waved frequently and the amplitude is big,it＇s found that the stratums of Permian and Triassic in north edge of the platform is unconformity,the hiatus is terrible.It＇s different from the former acknowledgment.The geometry of the stratigraphic framework shows obvious uniformity of the north and south edge in Lower Triassic Series. |
