| 摘 要： | 通过岩心观察 ,结合测井曲线和地震反射资料分析 ,并根据层序地层和层序界面的识别标志 ,建立了苏里格庙地区的层序地层格架 ,并将上古生界划分为 3个二级层序 (超层序组 )和 15个三级层序 ,其中本溪组和太原组的层序具二元体系域结构 ,即由海进体系域和高位体系域组成 ;山西组、石盒子组和石千峰组的层序具三元体系域结构 ,包括低位体系域、湖进体系域和高位体系域。剖析了陆表海浅陷沉积、陆表海碳酸盐岩与碎屑岩混合沉积及近岸内陆河流—三角洲—湖泊沉积超层序组 (或层序组 )中层序的发育特征 ,论述了层序的演化过程。

| Abstract: | Based on analyzing of outcrops, well-logging and cores data, the framework of Permian-Carboniferous sequence stratigraphy is built in Suligemiao area. 3 supersequences and 15 sequences in Upper Paleozoic have been identified. The formation in Carboniferous consist of 2 sequences and in Permian consist of 13 sequences. The sequence in Benxi Formation and Taiyuan Formation have the tharacteristic of 2 traces which include transgressive system tract and highstand system tract. The sequence in Shanxi ation, Shihezi and Shiqianfeng Formations consist of 3 tracts which include lowstand system tract, transgressive system tract and highstand system tract. The evolutionary of sequences reflect the process from epicontinental deposition to river-delta-lacustrine deposition in Permian-Carboniferous. |
