摘要
对济阳地区石炭-二叠系沉积特征、沉积相、沉积体系的研究表明,济阳坳陷上石炭统主要发育障壁-泻湖沉积体系。层序地层划分结果为:上石炭统陆表海充填沉积的三级层序为二元结构,即下部为海侵体系域,上部为高水位体系域,缺少低水位体系域,体系城的分界面为最大海泛面。二叠系的三级层序为三元结构,即下部为低水位体系域、中部为水进体系域、上部为高水位体系域。
A study on the sedimentary features, facies and systems of the Carboniferous - Permian in Jiyang area reviews that barrier bar - lagoon system is the main sedimentary system in the Upper Carboniferous in Jiyang depression. Sequence stratigraphy is divided. The third grade sequence of the Upper Carboniferous has binary structure - the lower part is transgression tract, the upper part is high water level tract, while low water level tract is absent, and the third grade sequence of the Permian has ternary structure - the lower part is low water level tract, the middle is transgression tract, while the upper part is high water level tract.
