摘要
对廊固凹陷旧州-固安构造带沙三段(Es_3)的研究发现,根据高分辨率层序地层学原理进行的地层对比结果不同于传统“粗对粗、细对细”的岩性地层对比结果。经过重新建立层序地层格架,对旧州-固安构造带进行地层对比,改变了传统“粗对粗、细对细”的地层对比方法,并修正了原有的地质构造特征。
It is found from the study of Es3 in Jiuzhou-Gu'an tectonic belt of Langgu Depression that the result of starti-graphic correlation obtained with high resolution sequence stratigraphic principle is distinguished with that of traditional coarse to coarse grain rocks and fine to fine grain rocks. Through reconstruction of the sequence stratigraphic frame and the stratigraphic correction of Jiuzhou-Gu'an tectonic belt, the traditional methods of coarse to coarse and fine to fine grain stratigraphic correlation are changed and original geologic structural features are corrected.
