| 摘 要： | 那江盆地是十万大山盆地北侧的一个中小型断陷盆地之一。本文根据陆相盆地层序地层的构造背景、控制因素及层序边界和内部结构特征等方面对那江断陷地层进行层序地层初析，确定出４个层序边界，划分出２个超层序（二级旋回）和３５个层序（三级旋回）；识别出冲积体系域（ＡＳＴ）、湖泊扩展体系域（ＥＳＴ）和湖泊萎缩体系域（ＲＳＴ），初步探讨了断陷盆地层序地层的特征及其控制因素。

| Abstract: | The NaJiang basin is one of meddle and small--sized
erlian fault basins on north of Shiwandashan basin According to tectonic settings,
controlling factors,characteristies of the sequence boundary and interal stracture in the NaJiang
erlian fault basin, four sequence boundaries, two supersequences (second-scale cyclic) and
three point five sequences (third-scale cyclic) were determined. Three systems tiacts were
recognized, including the alluvial systems tract (AST), lacutrine expanding systems tract(EST)
and lacustrine receding systems tract(RST).Preliminary analysis for characteristies and
controlling factors of these sequences strat in the erlian fault basin. |
