| 摘要: |
| 本文对四川江油马鞍塘中晚三叠世地层剖面进行了详细描述,根据岩石组合特征,结合全国岩石地层清理方案将其划分为天井山组和马鞍塘组[1]。对天井山组和马鞍塘组进行了详细的沉积相及垂向变化规律研究,并将其划分为四个层序(相当于三级层序),同时讨论了各层序的体系域特征[2]。 |

| Abstract: |
| The present paper gives a detailed description of the Ma'antang Middle-Upper Triassic stratigraphic section in Jiangyou,Sichuan.The Middle-Late Triassic strata in the section are assigned,according to rock associations referenced from the national lithostratigraphic classification, to the Tianjingshan and Ma'antang Formations which are subdivided into four sequences including SQ1,SQ2,SQ3 and SQ4 corresponding to the third-order sequences.The systems tracts in each sequence are also discussed. |
