| 摘 要： | 运用层序地层学的原理,在野外剖面沉积相、岩性、岩相和可容空间变化分析的基础上,对川东北地区宣汉县渡口镇羊鼓洞上二叠统剖面的层序地层进行研究,识别出3种类型6个层序界面,将上二叠统划分为1个Ⅱ层序和5个Ⅲ级层序,其中吴家坪组划分为3个Ⅲ级层序、长兴组划分为2个Ⅲ级层序。并在层序划分的基础上建立了川东北地区上二叠统的层序地层格架。将可容空间变化曲线与露头层序地层划分之间进行对比发现,二者之间存在着良好的对应关系。这不仅验证了层序划分的正确性,而且说明了Fischer图解旋回分析技术的实用性和客观性。

| Abstract: | On the basis of stratigraphic theory and the analysis of sedimentary facies,lithology and lithofacies and the changing of accommodation of field profile,sequence stratigraphy are researched to the upper Permian at Yanggudong profile in Dukou town,Xuanhan County,Northeastern of Sichuan Basin.Three types and six stratigraphic sequences boundary are discriminated.One 2-order sequence and five 3-order sequences in upper Permian,three 3-order sequences in Wujiaping Formation and two 3-order sequences in Changxin... |
