摘要
首先对济阳坳陷古近系层序地层学研究概况进行了系统的综述,并从层序地层界面的划分和层序地层发育控制因素及填充模式及高精度层序地层等方面叙述了济阳坳陷层序地层研究取得的主要进展。对济阳坳陷一、二、三级层序界面特征及体系域划分进行了引述,并记述了以气候变化、构造运动为控制因素的层序发育模式及干旱盐湖型、深水断陷湖盆型和浅水断陷湖盆型等三种层序填充模式。同时,对具有特色的陆相断裂坡折带和低位扇理论进行了阐述。在此基础上,针对济阳坳陷层序地层学的研究现状提出了今后的研究方向。
First,systematically summing up the general situation of the Paleogene sequence stratigraphic studies of the Jiyang Depression. An account of the chief advances in the sequence stratigraphic studies of the Jiyang Depression was given from the angles of the division of sequence stratigraphic interface and the sequence stratigraphic developmental controlling factors and filling models, as well as highly process sequence stratigraphy. Features of the first-.second-, and third-order sequence interfaces and division of system tracts were cited. Sequence developmental models taking climatic changes and tectonic movement as controlling factors and three kinds of sequence filling models such as dry saline lace,deep-water fault lake basin, and shallows-water fault lake types were recorded. At the same time, characterful continental slope-break Tone and theory of low fan are elaborated. On the basis, a direction is suggested for the present study of sequence stratigraphy of the Jiyang Depression.
