| 摘 要： | 莫里青断陷西部在始新世双阳组沉积时期发育ＮＥ，ＳＷ和ＮＷ方向三个浊积扇体，其中ＮＥ向浊积扇体仅发育于湖平面上升初期（双一段沉积时期），ＳＷ向浊积扇体在湖平面上升初期、上升早期和快速上升时期（双一，双二和双三段沉积时期）始终存在，而ＮＷ向浊积扇体形成于湖平面上升早期（双二段沉积时期），并一直持续到湖平面快速上升时期（双三段沉积时期）。目前在区内仅钻遇中扇水道、中扇过渡带和外扇沉积。

| Abstract: | The orogenic belt of the Late Palaeozoic in Jilin province was a part of the fold orogenic belt which belong to the system of divergence and convergence between the Siberia plate and Zhong chao plate. It was also a joint part of the circum Pacific tectonic region. By this reason its geological structure was very complex. Now the block of the rock strata were moved as a result of frequently tectonic movement. Based on the study of biostratigraphy, sedimentary geology, structural geology and geochemistry, the authers of this paper studed in detail the biogeo graphical area, lithofacies and palaeogeography. It has been for the first time found that the orogenic belts of Permian is composed of four migrated geobodies. ie, Yanbian, Jizhong, Songliao and Baicheg. According to the charaterestic of bio palaeogeography, judge of material composition and sedimentary sequence, we reconstructed the palaeolatitude and palaeotectonic history of each geobody. And finally with combination of geodynamic analysis anism, we reconstucted the prototype of tectonic palaeogeography of Early Late Permian. The basin was a complex maginal marine basin with active continental margin. |
