摘要
松辽盆地上侏罗统—白垩系层序地层学研究表明 ,由于海相环境与陆相环境之间存在着诸多差异 ,决定了海相层序与陆相层序在形成机制上 ,特别是在主控因素上显著不同。陆相盆地层序的形成主要受构造、气候因素的控制 ,也受沉积物供给和海平面升降的影响。上述诸因素通过综合作用影响着基准面和可容空间的周期性变化 ,进而控制着各级层序的发育和内部结构特征。
The research on Upper JurassicCretaceous sequence stratigraphy of Songliao basin indicate that obvious differences of mechanism of formation, especially in the main control factors, exist in between marine sequence and continental sequence related to the differences of their environment. The development of continental sequence are mainly controlled by tectonic and climate factors, sediments supply and sea-level change are secondary factors. All the above factors comprehensively interact each other which affect the periodical change of base-level and accommodation, in turn, control the development of continental sequence and the features of its internal structure.
