| 摘 要： | 研究了济阳坳陷石炭-二叠系沉积体系特点，进行了层序划分。研究表明，在济阳地区晚石炭世到早二叠世的沉积序列中，障壁-泻湖沉积体系比较发育，尤其是障壁砂坝的多次出现，与鲁西区一般以潮坪体系为主的特征具有明显不同。微量元素及其分布规律在分析沉积环境中具有重要意义，着重讨论了利用微量元素的分布规律进行层序划分和确定层序相关界面。

| Abstract: | The characteristics of the sedimentary system of Permo-carboniferous system in Jiyang sag have been studied and sequences classified by the authors. The results show that there is well developed barrier-lagoon depositional system in the upper carboniferous and lower Permian sedimentary series in Jiyan area, and sand bar appeared several times, which exhibits a striking difference from that in Luxi area where the tidal flat system grew well. Microelement and its distribution law play an important role in sedimentary environment analysis. The paper concentrates on the application of microelement distribution law to the classification of sequences and determination of interfaces and sequences. |
